Casting Forging
d) Jig is a device designed for holding the job and grinding the path of tool for a particular
operation on a number of similar operations. A fixture is used to hold and support the work
piece in a predetermined position for a particular machining operation.
Uses of jigs and fixtures are as follows:
1) Jigs quickly and accurately guide the tools .Difficult operations are rendered easier,
speedier, and yet more accurate by using jigs.
2) Jigs help in mass production by producing accurately machined interchangeable parts.
3) Fixtures are essential in all machine work, because work must be firmly held at the time
of working of tools.
4) Fixtures used along with jigs increase the speed and accuracy of work.
Q6. (a) Discuss the points to be considered while designing a Maintenance programme for
an organization?
(b) Product A has a Mean Time Between Failures(MTBF) of 30 hours and has a Mean Time
To Repairs (MTTR) of 5 hours. Product B has an MTBF of 40 hours and has an MTTR of 2
hours.
(i) Which product has higher reliability?
(ii) Which product has greater maintainability?
(iii) Which product has greater availability?
(c) The probabilities of failure pn of an equipment in the nth period after maintenance have
been estimated as follows :
n 1 2 3 4
pn 0.1 0.2 0.4 0.3
Cost of preventive maintenance : Rs.150
Cost of breakdown maintenance : Rs 1000
Determine the optimum frequency of preventive maintenance.
Answer 6.
(a) While designing a maintenance programme the main objective of management should be to
educe the total cost of maintenance without sacrificing the efficiency and effectiveness of
the plant. The following points are to be considered while designing a maintenance programme:
(i) The maintenance operation should increase the life of the asset at affordable cost.
(ii) The maintenance programme should not affect the normal working of the plant. This involves
proper planning, having spare machines etc.
(iii) Manpower required for maintenance plan should determined and proper training should be
imparted to them.
Forging is a process of heating the metal into
red and then hammering it into shape.
Examples ,drop forging, press forging etc.
Casting is a process of pouring a molten metal
into prepared cavity or mould and allowing it to
solidify. Examples , sand casting, centrifugal
casting.
Group-II : Paper-9 : Operation Management and Information Systems 81
(iv) The equipments may be classified according to their criticality.
(v) Lubrication schedules should be prepared, spares and equipment replacement policy should
be decided.
(vi) The maintenance plan should be communicated to all concerned.
(vii) Modern techniques like OR, PERI to be employed in carrying out maintenance.
(viii) Maintenance standard time may be fixed.
(ix) The programme itself may have to be modified in light of the experience gained.
(b) (i) The product having higher MTBF will be more reliable, as it will have a lesser chance to
fail during service. Product B has higher MTBF (40hrs.) So it is more reliable.
(ii) MTTR means time by which the machine can be repaired and put to use. Since MTTR of B
is less than that of A , it has a greater maintainability.
(iii) The availability may be computed as follows :
Availability of A= MTBF/(MTBF+MTTR)*100
=30/(30+5)*100
=30/35 *100
=85.7%
Availability of B = MTBF/(MTBF+MTTR)*100
=40/(40+2)*100
=40/42*100
=95.2
(iii) (a) It has been assumed that equipments that fail are replaced just before end of the
week.
(b) Actual percentage of failures during for equipments of same age is same as the expected
percentage of failure during the period for them.
Period Prob. of No. of replacements Cost of Cost of Total cost Cost

(0.1*0.2)=0.4+ =441 =901 =300.3
0.021+0.02
=0.441
Therefore optimum frequency of preventive maintenance is once in 2 periods and expected cost
of maintenance is Rs.230.
Q7. (a) Define work sampling. Write down the formula indicating terms used for determining the
sample size.
82 Revisionary Test Paper (Revised Syllabus-2008)
(b) In a sampling study, a machine is found to be idle 20% of the total time available for
operation. Find out how many observations are required to arrive at a more accurate
estimate with a confidence level of 95% and +/- 5 % error limit.
Answer 7.
(a) Work sampling is a work measurement technique in which a sufficient large number of
instantaneous observations of an worker or machine are taken over a period of time to
obtain a reasonably accurate picture of the time spent on different activities. It is based on
statistical theory of sampling. Work sampling is thus a method of finding out percentage
occurrence of a certain activity or delay by statistical sampling. The procedure of work
sampling consists of following steps:
i) The purpose of study to be determined first.
ii) The worker or machine to be identified.
iii) The operations to be observed to be decided.
iv) The number of observations to be made to be decided.
v) The activity performed at each visit to be recorded.
vi) Percentage of total time spent on each activity to be calculated.
vii) Standard time is established by adding allowances.
The formula deciding the sample size is as follows:
n={4p(1-p)}/s2p2 where,
n=sample size
p=extent of activity being observed.
s=accuracy of sample results.
(b) n={4p(1-p)}/s2p2
p=0.2
1-p=0.8
s=0.05
n=4*0.2*0.8/(.05)2*(.2)2
=.8*.8/.0025*.04
=6400
Q8. (a) Distinguish between Quality of Design and Quality of Conformance
(b) What causes variations in Quality?
(c) AB Ltd. manufacturer of floppy disks inspects a sample of 50 disks from each days
output. Data relating to number of defectives over past 20 days is given below:
Date No. of defectives
18.2.08 3
19.2.08 10
20.2.08 13
21.2.08 4
22.2.08 12
23.2.08 14
24.2.08 8
25.2.08 7
26.2.08 19
Group-II : Paper-9 : Operation Management and Information Systems 83
27.2.08 1
28.2.08 0
1.3.09 4
2.3.09 9
3.3.09 22
4.3.09 7
5.3.09 6
6.3.09 18
7.3.09 3
8.3.09 9
9.3.09 7
As per production manager variation in quality was due to deputation of inexperienced substitute
operator instead of regular one on 3 days during this period. With use of control charts specifying
upper and lower control limits, determine the days of poor quality which can be assigned to the
inexperienced operator. Do the number of such days match the number of points indicating out of
control situation ?
Answer 8.
a) Difference between Quality of Design and Quality of Conformance :
Quality of design Quality of conformance
Refers to manufacturing specification of Refers to degree to which the product
product. It consists of appearance, life, actually conforms to design specification.
safety and other features of product.
Higher quality means higher cost. Higher quality means lower cost.
b) Variation in quality occurs due to chance causes and assignable causes. Chance causes are
inherent in the process .It is difficult and uneconomical to detect and eliminate them. They are
random and independent of each other and are natural and permissible.
Assignable causes are due to improper raw material, bad working, or negligence on part of the
worker. They are non random, identifiable, and controllable.
c) Proportion of defectives = Total no. of defectives/No. of observations.
= 176/(20*50)
= 76/1000
= 0.176
Sd = square root of p(1-p)/n
= square root of 0 .176*(1-0.176)/50
= square root of 0 .0029
= .054
84 Revisionary Test Paper (Revised Syllabus-2008)
p=proportion of defective
n=sample size
Therefore UCL= p+3sd=0.176+3*0.054=0.176+0.162=0.338
LCL =p-3sd=0.176-3*0.054=0.176=0.162=0.014
CL=p=0.176
Plotting the chart datewise, we find data outside the chart on 26/2, 28/2, 2/3 and 5/3 respectively.
Ignoring 28/2, on other three days poor quality may be assigned to inexperienced operator. So
production manager’s assertion is right.




































Q9. Describe in brief the concept of FMS. What are its advantages and disadvantages?
Answer 9.
A Flexible Manufacturing System is a hybrid between continuous and intermittent flow of production.
Here, using computer controlled machine and automated material handling equipment, a continuous
flow is instilled in otherwise high variety, low production volume flow. Thus FMS is builds on the
Group-II : Paper-9 : Operation Management and Information Systems 85
programmable automation of NC and CNC machines. Programs and tooling set up can be quickly
changed and production can be switched on from one job to another without any loss of changeover
time.
Key components of FMS are :
i) Several computer controlled workstations having CNC machines and robots for loading and
unloading.
ii) Computer controlled transport systems for moving materials and parts from one machine to
another.
iii) Computer controlled robots for loading and unloading stations.
iv) An automated storing and retrieval system.
The above subsystems of FMS are controlled by a central computer with the needed software.
Advantages of FMS can be broadly divided into following :
i) Flexibility: With slight changes in programs the system can be used with less recurring
capital investment.
ii) Adaptability: With little training the supervisors can take up family of jobs earmarked to the
system.
iii) Wider scope: Advanced manufacturing technology continuously opens newer application
areas.
iv) Lesser human effort results in less amount of human error.
v) Improved productivity through better quality, effective control of a small area.
Disadvantages of FMS are as follows:
i) High initial capital investment.
ii) Limited ability to adopt to production changes.
iii) Substantial preplanning, tooling and fixture requirements.
iv) Standardisation of part design required to reduce the number of tools.
v) Long planning required to install FMS.
Q10. (a) Two alternative methods X and Y using different tooling set-ups may be employed to
manufacture a component on a particular on a particular machine tool whose operating
cost is Rs. 20 (including wages of operator) per hour.
Particulars Method X Method Y
Component 4000 pieces 3000 pieces
Cost of tooling Rs. 320 Rs.1500
Production rate per hour 10 pieces 15 pieces
Justify with suitable calculation which of the two methods would you choose as being more
economical for regular production? Would your answer be different if only 1000 pieces of particular
component are required?
(b) Perfect Machine Tools Ltd. requires 4000 pieces of a bought out component in a year.
Price of the item is Rs. 3 and it has been estimated to cost Rs. 60 to place an order. If
carrying cost is 25% of the value of inventory held, find the optimum size of order.
86 Revisionary Test Paper (Revised Syllabus-2008)
Answer 10.
a) The unit cost of two methods are as follows:
Method X Method Y
Cost of tooling Rs. 320 Rs.1500
Hours required 4000/10=400 3000/15=200
Operating cost 400*20=Rs. 8000 200*20=Rs. 4000
Total production costs Rs. 8320 5500
No. of pieces 4000 3000
Cost per piece Rs. 2.08 Rs.1.83
Therefore Method Y is more economical.
If only 1000 pieces are required the cost would be as follows:
Method X Method Y
Cost of tooling Rs. 320 Rs. 1500
Hours required 1000/10=100 1000/15=66.67
Operating cost 100*20=2000 66.67*20=1333.4
Total cost of production 2320 2833.40
Cost per unit Rs. 2.32 2.83
In this case X is cheaper.
b) The formula for calculating economic order quantity is as follows:
EOQ=Square root of [2*Annual Requirement*Ordering Cost]/Cost per unit*carrying cost
= Square root of[2*4000*60]/3*0.25
= Square root of 640000
= 800
Thus optimum ordering cost is 800 pieces.
Q11. (a) Explain the meaning of plant layout.
(b) What are the principles to be borne in mind while designing a plant layout.
Answer 11.
(a) Plant layout implies physical arrangement of machines, equipments and other facilities on
the factory floor in such a manner that they may be handled efficiently. Plant Layout, also
known as layout of facility refers to the configuration of departments, work-centres and
equipment and machinery with focus on the flow of materials or work through the production
system. Plant layout or facility layout means planning for location of all machines, equipments,
utilities, work stations, customer service areas, material storage areas, tool servicing areas,
tool cribs, aisles, rest rooms, lunch rooms, coffee/tea bays, offices, and computer rooms
and also planning for the patterns of flow of materials and people around, into and within
the buildings. Layout planning involves decisions about the physical arrangement of economic
activity centres within a facility. An economic activity centre can be anything that consumes
space, a person or group of people, a machine, a work station, a department, an aisle, a
Group-II : Paper-9 : Operation Management and Information Systems 87
store room and so on. The goal or layout planning is to allow workers and equipments to
operate more effectively.
(b) Plant Layout- Principles :
The layout selected in conformity with layout principles should be an ideal one. These principles
are :
• Principle of Minimum Travel: Men and materials should travel the shortest distance between
operations so as to avoid waste of labour and time and minimise the cost of materials
handling.
• Principle of Sequence: Machinery and operations should be arranged in a sequential order.
This principle is best achieved in product layout, and efforts should be made to have it
adopted in the process layout.
• Principle of Usage: Every unit of available space should be effectively utilised. This principle
should receive top consideration in towns and cities where, land is costly.
• Principle of Compactness: There should be a harmonious fusion of all the relevant factors
so that the final layout looks well integrated and compact.
• Principle of Safety and Satisfaction: The layout should contain built in provisions for
safety for the workmen. It should also be planned on the basis of the comfort and
convenience of the workmen so that they feel satisfied.
• Principle of Flexibility: The layout should permit revisions with the least difficulty and at
minimum cost.
• Principle of Minimum Investment: The layout should result in savings in fixed capital
investment, not by avoiding installation of the necessary facilities but by an intensive, use
of available facilities.
Q12. (a) What is Human Resource Planning? Explain the steps involved in HRP.
(b) State the importance of HRP to an organization.
Answer 12.
(a) HRP is a process of striking balance between human resources required and acquired in an
organisation. In other words, HRP is a process by which an organisation determines how it
should acquire its desired manpower to achieve the organisational goals. Thus, HRP helps an
organisation have the right number and kind of people at the right places and right times to
successfully achieve its overall objectives. Human resource planning is a process of
determining and assuming that the organisation will have an adequate number of qualified
persons, available at the proper times, performing jobs which meet the needs of enterprise
and which provide satisfaction for the individuals involved.
HRP is the process- including forecasting, developing and controlling-by which a firm ensures
that it has the right number of people and the right kind of people at the right places at the
right time doing work for which they are economically most useful.
HRP can be defined as the comparisons of an organisation’s existing labour resources with
forecast labour demand, and hence the scheduling of activities for acquiring, training,
redeploying and possibly discarding labour. It seeks to ensure that an adequate supply of
labour is available precisely when required.
88 Revisionary Test Paper (Revised Syllabus-2008)
HRP could be seen as a process, consisting of the following series of activities:
1. Forecasting future personnel requirements, either in terms of mathematical projections
of trends in the economy and developments in the industry, or of judgements estimates
based upon specific future plans of the company.
2. Inventing present manpower resources and analysing the degree to which these re-sources
are employed optimally.
3. Anticipating Manpower Problems by projecting present resources into the future and
comparing them with the forecast of requirements, to determine their adequacy, both
quantitatively and qualitatively.
4. Planning the necessary programmes of recruitment, selection, training, employment,
utilisation, transfer, promotion, development, motivation and compensation so that future
man power requirements will be duly met.
(b) Human resource planning is important to organisation because it benefits the organisation in
several ways.
The important ones are mentioned below :
1. By maintaining a balance between demand for and supply of human resources, human
resource planning makes optimum use of human resources, on the one hand, and reduces
labour cost substantially, on the other.
2. Careful consideration of likely future events, through human resource planning might
lead to the discovery of better means for managing human resources. Thus, foreseeable
pitfalls might be avoided.
3. Human resource planning compels management to assess critically the strength and
weaknesses of its employees and personnel policies on continuous basis and, in turn, take
corrective measures to improve the situation.
4. Human resource planning helps the organisation create and develop training and succession
planning for employees and managers. Thus, it provides enough lead time for internal
succession of employees to higher positions through promotions.
5. Human resource planning meets the organisation need for right type of people in right
number at right times.
6. It also provides multiple gains to the employees by way of promotions, increase in
emoluments and other perquisites and fringe benefits.
7. Last but no means the least, with increase in skill, knowledge, potentialities, productivity
and job satisfaction, organisation becomes the main beneficiary. Organisation is benefited
in terms of increase in prosperity /production, growth, development, profit and, thus, an
edge over its competitors in the market.
8. Manpower shortfalls and surpluses may be avoided, to a large extent.
9. Some of the problems of managing change may be foreseen and their consequences
mitigated. Consultations with affected groups and individuals can take place at an early
stage in the change process. This may avoid resistance for change.
10. Through human resource planning, duplication of efforts and conflict among efforts can
be avoided, on the one hand, and coordination of worker’s efforts can be improved, on
the other.

of business.
v) Calls for change in conditions if that leads Aims at lowest possible cost under given
to lowering in cost. conditions.
vi) The programme can be finished It is ongoing or never ending process
ii) Production and productivity
Production and productivity are not synonymous. Production refers to the volume, value or quantity
of goods and services produced during a given period by a worker, plant, firm or economy. It is the
sum total of results achieved by the various factors used together. Productivity, on the other
hand, is not concerned with the volume of production. It is the ratio of output and input factors of
an enterprise. It shows the efficiency of production or the efficiency level of input factors. In
other words, productivity is relative to the resources used in turning out a certain amount of
physical output, while production is used, more or less, in absolute sense. The distinction between
two terms becomes more clear when we find that increase in production does not necessarily
mean the increase in productivity. If increase in production is attributed to the increase in the
inputs of production in the same proportion, the production will have increased but productivity
may have declined or may remain constant because the ratio of output and inputs has shown a
decline or has not shown any improvement.
iii) Job Analysis and Value Analysis
Job Analysis Value Analysis
a) Process of determining task components Systematic application of established techniques
or work content of a job so as to access to identify functions of product or component
relative worth of different jobs. and to provide those functions at lowest possible
cost.
b) Technique of merit rating Technique of cost reduction
Q14. (a) How do you classify Waste? Discuss the features of an effective Waste Disposal System.
(b) How can an organization control pollution?
90 Revisionary Test Paper (Revised Syllabus-2008)
Answer 14.
(a) There are various ways in which one could categorise waste. However, the generally
accepted classification is given below:
(i) Classification on the basis of Resources, i.e., how much of a particular resource has
been wasted.
(ii) Classification on the basis of property i.e. whether the materials that have been wasted
are hazardous to life and environment or whether they fall in the category of non-hazardous.
(iii) Classification on the basis of the recoverability of resources.
(iv) Classification on the basis of origin of waste, i.e., whether it is commercial waste or
industrial waste, residential waste or office waste and construction waste or agricultural
waste.
The salient features of an effective waste proposal system are as follows:
1. Easy to install and operate.
2. Economical from the cash outflow point of view.
3. Convenient and not highly complex.
4. Within the budgetary constraints.
5. Approved by the legislation and other statutory authorities in force.
6. Flexibility and not rigidity in operations.
7. Economies of scale.
8. Does not require highly skilled labour force for its operation.
9. Adaptability in the context of the needs and objectives of the organsiation.
(b) Pollution cannot effectively be controlled by the use of a single technique. Since the causes
and the effects of different types of pollution are diverse and distinct from each other,
there cannot be any thumb- rule or golden rule which could be applied in the present context.
However, in general, a prudent use of the techniques given below, in conjunction with other
appropriate measures, is bound to bring in the desired results. These are :
1. Controlling at source.
2. Controlling during processes, operations and other activities.
3. Control by suitable enclosures.
4. Control by protection.
5. Control by preventions.
6. Control by absorption.
7. Adhering to regulations laid down by the following authorities:
(a) Respective state governments.
(b) Central Government.
(c) Guidelines issued by the global bodies representing individual pollution control measures.
(d) Ensuring compliance with any other law for the time being in force.
Q15. Write short notes on:
a) Input-Output Analysis.
b) Factors affecting business forecast.
Answer 15.
a) Input-Output Analysis.
Input-output analysis reflects a general theory of production based on the idea of economic
interdependence. Many input - output models are useful in forecasting. Input - output analysis
Group-II : Paper-9 : Operation Management and Information Systems 91
takes into consideration the interdependence of the different sectors in the economy. This is
because; the input to one sector is output of another sector. For example, the output of coal
industry will be an input to the steel plant and the output of steel industry is an input to the
construction industry and so on. There are many such cyclic relations within the various sectors of
economy. Taking the data of outputs and inputs and studying the relationship between these two,
we will be in a position to analyse the total demand for a product and the output required from
industrial units. This type of analysis is very important because it takes into account all the intricate
relationships in the economy. One of the limitations in this method is that the utility of an output is
restricted to economic analysis, not considering the other business, governmental, technological
and internal factors. It is limited but useful analysis. The analysis need not be limited to macrolevel,
speaking only in terms steel sector and coal sector etc. It may be mote ‘micro’, by considering
the inputs and outputs within a general product group in the total economy. This type of analysis
is very much used and is found more beneficial and useful. Three major assumptions in developing
this technique are:
1. The total output of an industry is consumed as input by all industries for a time period, under
consideration.
2. The input bought by each industry has usually been made dependent only on the industry’s
level of output.
3. The ratio of an industry’s input to its output, once established is fixed. This ratio is known as
input output number or production coefficient.
Input-output analysis is a mathematical study of an economy in which different production sectors
such as agriculture, industry and services etc. have interdependence. Thus, in input-output analysis,
we try to analyse quantitatively the interdependence of inputs and outputs of various industries
and find the equilibrium between the inputs and output of each industry, plant, sector or economy.
The output of any industry depends very much on its inputs and these inputs are the outputs of
other industries. This analysis signifies to foretell the total production per sector and its demand in
other industries.
It can be presented as: Total output of all sectors = Total inputs of all sectors.
or, output of an industry = Total inputs of that industry.
This input-output analysis is also known as ‘analysis of inter-industry or inter-sector flows or
deliveries or analysis of inter-industry relations.’
Input-output analysis can be used in the following cases :
1. The input-output analysis can be used for the study of variation in productivity of an enterprise.
This analysis is based on index-numbers, using value added measure for output and the
measures of inputs all at constant prices. The value added in each industry can be obtained
by subtracting the value of inputs used from the value of gross output.
2. Input-output table has a historic importance showing a record of past and can be a very
useful instrument in economic analysis and framing economic policy. In developed countries,
this analysis is used for economic forecasting and in developing countries, for economic
planning or programming. In business world, business forecasting can be done by this analysis.
3. This analysis can be very usefully used for a comparative study of growth by examining. By
examining country-wise or sector or region-wise or plant, firm or industry-wise differences
in input-output coefficients, the process of growth can be more easily interpreted.
4. This analysis can be utilised to determine the impact of some major exogamous changes in
the economy on other factors of production.
92 Revisionary Test Paper (Revised Syllabus-2008)
b) Factors affecting business forecast.
Forecasting means peeping into the future. As future is unknown and is anybody’s guess but the
business leaders in the past have evolved certain systematic and scientific methods to know the
future by scientific analysis based on facts and possible consequences. Thus, this systematic
method of probing the future is called forecasting. In this way forecasting of sales refers to an act
of making prediction about future sales followed by a detailed analysis of facts related to future
situations and forces which may affect the business as a whole. Foresight is not the whole of
management, but at least it is an essential part of management and accordingly, to foresee in this
context means both to assess the future and make provisions for it, that is forecasting is itself
action already. Forecasting as a kind of future picture wherein proximate events are outlined with
some distinctness, while remote events appear progressively less distinct and it entails the running
of the business as foresee and provide means to run the business over a definite period.
Various factors that influence the forecast are:
(i) Environmental changes,
(ii) Changes in the preference of the user,
(iii) Number of competitive products,
(iv) Disposable income of the consumer.
In forecasting the production important factors to be considered are:
(i) Demand from the marketing department,
(ii) Rate of labours absenteeism,
(iii) Availability of materials,
(iv) Available capacity of machines,
(v) Maintenance schedules,
(vi) Delivery date schedules.

Q5. Distinguish between :
i) Hardware and software
ii) Third generation and Fourth generation languages
Answer 5.
i) Hardware and Software
Hardware Software
ii) Third Generation and Fourth Generation Languages
Third Generation Languages are called procedural languages and they are procedure oriented.
They employ plain English like and mathematical expressions. They are intended for professional
programmers, and require specification of how to perform task. Programmes written in third
generation languages are also difficult to debug and usually translated through compiler.
Code is difficult to learn, understand and maintain. These languages were originally developed
for batch operations and are typically file oriented. FORTRAN, COBOL etc. are examples of
third generation languages.
Fourth Generation Languages(4GLs), on the other hand, can be used by both programmers
and non-programmers. 4GL uses English like instructions, has limited mathematical manipulation
capability. It offers automatic report formatting, sequencing and record selection by user
given criteria. However, 4GLs are less efficient than third generation languages. They require
specification of what task to perform and the system determines how to perform that task.
Physical components of a computer system
are called hardware.
Collection of programs designed for specific needs
is called software.
Input devices, processing unit, output devices
and auxiliary storage devices are different
categories of hardware.
Software can be divided into three typesapplication
software, system software and
general-purpose software.
Keyboard, mouse, printer, CPU, RAM are
examples of hardware
Financial Accounting software, operating system,
MS-WORD etc. are examples of software.
Hardware is manufactured/assembled by
hardware manufacturing companies/
hardware vendors.
Software is developed by softwaredevelopment
firms.
Hardware is independent of software. Software cannot be developed/used without
hardware i.e. software is dependent on hardware.
Hardware repair requires hardware engineer. Software development/modification requires
software professionals like application programmer
and system programmer.
It is bulky and requires more storage space. Software can be copied on CD/DVD, which is
lightweight and transportable.
Hardware is supported by uninterrupted
power supply (UPS).
Software operation requires requisite hardware.
Hardware can be assembled, Indian branded
or of MNC brand.
Software can be licensed or pirated.

4GL requires fewer instructions, code is easy to maintain and understand. Many features of
4GLs can be learned quickly. 4GLs are more structured and are data base oriented. Generally,
these are available in two types (i) Production Oriented and (ii) User Oriented
Q6. (a) What is Information? How does it differ from Information System.
(b) Describe the characteristics of an Information System.
(c) Explain why information system die.
Answer 6.
(a) Information is data that has been processed into meaningful form so that it can be effectively
interpreted and help the user in decision making. Information consists of data, text, images,
voice etc. On other hand, Information System is the vehicle that supplies necessary
information for decision making. The information system is to feed the management for
control purpose. The activities in an information system are :
(i) collection, storing and processing of data.
(ii) generation of information reports.
(iii) dissemination of information to right users.
(b) Characteristics of an Information System : The following are the general characteristics of
an Information system :
(i) Specific objective : The information system should have some specific objective. An
Information System in highly scientific research centre will have an objective to accumulate
date from different activities, display of some information instantly for controlling
acitivities and son on. In a business environment, the objective will be sharing information
from different functional areas and smooth flow of information for management decision
making.
(ii) Structured : An information system have a definite structure with all modules of subsystems.
The structure depends on the sub-modules, their interactions and integration
requirements, operational procedure to be followed and the solution sets. The structure
of the information system refers to diagrammatic representation of the system showing
sub-systems, their inter-relation and the procedure to be followed to fulfill the process
requirements.
(iii) Components : The sub-system are the components. The sub-systems should be
distinguishable amont themselves but have well-defined relation among. For example, a
Sales system may be sub-systems like Invoicing, Delivery monitoring, and Sales Proceeds
Collection system. The inter-link between these systems must be well defined.
(iv) Integrated : An Information System should be designed in such a fashion that proper
integration among sub-systems are taken care to establish correct linkage an generate
meaningful information. An information in isolation may not be that meaningful but its
usage is improved if it is integrated with information of other closely related issues. For
example, Sales information of a region becomes more meaningful if other information
like previous period sales, sales in other regions, sales of competitive products are also
combined in the information set.
(v) Life-Cycle : An Information system will have its won life-cycle. The duration of life cycle
varies from the system to system. An information system has the similar stages of lifecycle
as seen in any other system. Every information system will have distinctly phases
— Initial, Growth, Maturity and Decline.
Group-II : Paper-9 : Operation Management and Information Systems 99
(vi) Behaviour : A system has its own set reaction and outcome depending on the environment.
A well managed business information system behaves nicely with its users by satisfying
them with correct andtimely information. The design of the system plays a good role in
setting its behaviour pattern.
(vii) Self-regulatory : An Information System which may have different sub-systems interacting
with the each other in a desired fashion to be operative smoothly and in the process they
regulate themselves. This is what is self-regulatory nature of the system. A payroll
system involves three activities—first, maintaining attendance of employees, second,
pay calculation and third pay disbutsement. It the target date for pay disbursement is
last date of a month, the second adjusts its start time accordingly and the first one is
also regulated in such a fashion that it can provide input to the second in time.
(c) Information Systems die due to changes in information requirement and information becoming
outdated due to :
(i) changes in business environment
(ii) changes in users’ expectation
(iii) changes in technology
(iv) deterioration in software quality due to passage of time
Q7. Write short notes on:
a) ALU
b) Virtual Memory
c) Bootstrapping
d) Virus
e) HLL
Answer 7.
(a) ALU-Arithmetic and Logical Unit is a component of Central Processing Unit of Computer
Hardware. It has three gates –mathematical gates, logic gates and register. Mathematical
gates perform mathematical function, logic gates are involved in logical operations and
register acts as temporary storage for data. Arithmetic operations means addition only,
whereas subtraction is addition of complements, multiplication is repetitive addition and
division is repetitive addition of complements. Logical operations basically involve comparing,
selecting and matching of data.
(b) Virtual Memory: Virtual Memory is a secondary storage facility acting as primary memory
in a Computer System. When the size of main memory is less than required size for a
program to run, the operating system enables it with the help of hard disk (main storage
media). The system followed is breaking the programs and accommodating the part according
to the size of main memory available and rest is stored in hard disk. When a part of program
stored in hard disk is required for running the program, a part of the program stored in the
main memory is transferred to hard disk and the required part is brought to main memory.
This process is called swapping.
(c) Bootstrapping: Bootstrapping means loading Operating System in Computer after switching
on the power. Bootstrapping instructions are stored in RAM. Once the power is on the
computer takes bootstrapping instructions from ROM and loads the OS from Hard-disk into
RAM and the computer is put in operation.
(d) Virus : It is a software which is directed to destroying software or information in a computer.
It is generally carried along with a program or data through a device without the knowledge
100 Revisionary Test Paper (Revised Syllabus-2008)
of the user. The virus software is activated at encountering a particular situation either in
terms of time or action. It gets multiplied automatically that means it gets copied from one
file to other in an attempt to make the damage wider. There are varieties virus and their
actions are different. It destroys software, data file and even file allocation table ( FAT).
The virus software was developed to interfere with free exchange of program in order to
make the users to buy software by paying due price for it to protect the interest of software
developers. But its subsequent indiscriminate use has gone beyond ethics to affect the
resources and free exchange of programs among the users.
(e) High Level Language (HLL) : High Level Languages were developed in such a fashion that
the instructions are alike to English Language so that following the instruction codes and
writing programs become easier. This helped the programmers to overcome the shortcomings
of low level languages to a great extent. The following are the features of High Level
Languages :
• They are English like Languages and easy to learn.
• Standard sets of words and well defined structures are used.
• Program development effort is less.
• Debugging is easy.
• Portability is high.
• It is not machine dependent.
• It was procedure oriented thereby reducing programming effort.
Q8. What is:
i) CBA of a system.
ii) Debugging.
iii) Flow Chart
Answer 8.
(i) Cost - Benefit Analysis: This is basically to justify the financial feasibility of a system.
Before a new system is proposed, the benefits derived out of it should be weighted with the
cost in it. Cost components which should be covered in the analysis are :
• Investment requirement in hardware procurement /rent
• Cost of software development
• Maintenance of hardware
• Cost of creation/conversion of data files
• Manpower cost
• Cost of computer stationery including floppies, tape etc
• Training cost
• Cost of maintenance of software
• Overhead cost – power, air-conditioning, rent etc
Group-II : Paper-9 : Operation Management and Information Systems 101
Financial and non-financial benefits from the system are assessed.
Tangible benefits :
• Decrease in data processing cost
• Saving through better information system
Intangible benefits : It is difficult to estimate them. They are like:
• Increased operational efficiency
• Good working environment
• Better information system etc.
Cost and benefits are weighted and observations are made accordingly for proper decision making.
Generally System objectives outline the following :
• How the new system meets the changes in requirements
• Technological improvement envisaged
• Skill improvement plan for manpower
(ii) Debugging a program means eliminating errors in the program. Errors may be of two types
- a) Syntax error and b) logical errors
Syntax errors : These are errors due to mistake in following the syntactical structure of the
language in which the program is developed or there may be spelling mistake in the use of
words and instruction codes. These errors are detected at the time of compilation with the
help of a compiler. Unless the syntax errors are corrected, object program will not be
generated.
Logical Errors : These are errors in program logic. These are generally detected at the time
of execution or testing the program. Due to logical errors, program may fail to run or will
generate wrong output report.
(iii) Flow Chart is the diagrammatic representation of the algorithm i.e. program logic. It uses a
unique set of symbols to describe the conditions and actions.
Technique of in drawing flow chart
• Starting with the input for main decision factor
• Putting the condition in the decision box
• Branching the condition into different path of decision box
• Branching should be done without ambiguity
• To remove ambiguity, more than one decision box may be used
• Writing the statements under each branch
• Avoiding crosses in the flow chart
• Using connectors to reduce the number of flow lines, if required.
Advantages of Flow Charts :
• Logical representation of problem steps
• Flow chart helps to make the complex logic simpler
102 Revisionary Test Paper (Revised Syllabus-2008)
• A visual aid in conceptualization of the problem
• It is tool for efficient programming
• Helps in debugging
• Support program documentation
Q9. (a) What is a Decision Support System? Illustrate with diagram.
(b) Mention the main components of DSS.
Answer 9.
(a) According to CIMA, Decision Support System (DSS) is a collective term to describe the
various types of software, principally modelling or simulation, which provide input into
management’s decision making process. The ‘what if?’ analysis produced by spreadsheets
is a typical example.
Decision support system is an IT tool based on models for interpretation and analysis of data
and presenting the same for facilitating decision making. An expert system is within the
DSS so that unstructured problems are also taken care.
Decision Support System has the following three characteristics:
i) Support semi-structured and unstructured decision making
ii) Use model for solutions
iii) Flexible to respond the changing need of the decision maker
Structured or Programmed decision making is with the help of using data in a simple related
decision making program which is based on technical knowledge on a particular area.
Unstructured or semi-structured decision making process involves a great technical expertise
of the all subjects of all related fields and building model to handle the information to derive
solution set.
Decision Support System









Group-II : Paper-9 : Operation Management and Information Systems 103
(b) A DSS has the following three components :
(i) Databases – A DSS must have one or more databases containing all relevant information.
The system will extract the set of information from database with data-mining tools.
(ii) Model base – Model base is the brain of a DSS. For example, mathematical models on
Time Series analysis, Linear Programming, Statistical Quality Control will be tools used
to solve many financial problems.
(iii) Technical Expertise – A DSS system must have technical expertise in the domain field to
understand the nature of information, nature of problems, appropriateness of model and
additional intelligence required to handle the unstructured or semi-structured problem
situations.
Q10. (a) Explain the terms management, information and system. In this context define MIS.
(b) State the steps involved in implementation of MIS.
Answer 10.
(a) Management is the process of getting things done through human efforts to achieve the
objectives of the organisation.
Information is data that has been processed into meaningful form so that it can be effectively
interpreted and help the user in decision making.
A system is a set of interrelated elements that function as a whole.
MIS is the system of collection, processing, retrieving and transmission of data to meet the
information requirement of different levels in an organization.
(b) For establishment of MIS in an organization, the following steps are followed :
Analytical study on information requirement: A joint efforts by systems experts and
management experts is required to understand the exact need of information at different
levels of management and how to assimilate them from data flow from different sources.
The anticipated change in the need of information may be kept in mind while planning the
design in order to provide sufficient flexibility in the system.
Determine the sources of information: Once the first step is understood, it is to see how to
get the required information and their sources. If required, data recording system may be
changed at different points so that exact data flow is ensured and the same can be done
without much hazards. For the sake of simplicity of the system reorientation in the physical
flow of data has to be done.
Establishment of right kind of data processing environment: The important step involved in
MIS designing is arranging the right kind of tools for processing i.e Computer System and
infrastructure in terms of software and skilled manpower. The proper scheduling of processing
is equally important to ensure smooth flow of information.
Selection of software: One of the important factors of success for MIS is quality of software.
Software must fulfill the following criteria :
• Compatibility of hardware
• Capable of taking load of data volume
• Have the support of software for required database
• Capable of supporting the communication network
• Satisfy the design specification of system architecture – Central data processing or
distributed data processing
104 Revisionary Test Paper (Revised Syllabus-2008)
Database design : In database design the important issues involved are sub-systems in the
organization and the logic of integration. Technical knowledge of database and knowledge
of application systems, their control requirements and designing of reports are essential for
efficient designing of database.
Support of top management : To ensure the smooth functioning of MIS top management
support is required. Top management will support only when they are convinced about the
benefit of MIS of the organization and confident of efficient performance of processing and
regular reporting. Thus, for support of top management, efficiency of MIS has to be
established.
Manpower: Arrangement of right kind of manpower with proper skill is the most consideration
for successful operation of the system. Proper planning for training of manpower involved in
transaction processing and report generation under an MIS system is required to take care
of future development of the system.
Integration of information: At the time of designing the data bases, provision for integration
of information from different sub-systems is essential so that comprehensive information
flow can be of great use for strategic planning.
Evaluation, maintenance and Control: The effectiveness of an MIS system is evaluated by
the capacity of its fulfillment of requirement of information by the management. Evaluation
is done by ascertainment of the views of the users. Maintenance is needed to take care of
the gaps, if any, for further growth and for regular smooth functioning of the system.
Control means establishment of checks for input data, processing and output to ensure
correctness of reports. Proper maintenance and control on effective operation of MIS required
to ensure protection from hazards and smooth functioning on a routine basis.
Q11. Explain the terms:
(a) ‘Going live’ in relation to ERP implementation.
(b) EIS
(c) Data Warehouse.
(d) AI
Answer 11.
(a) Going Live : In this phase, the system is to be finally implemented in new environment with
real life data set and to the satisfaction of the end-users. In ERP systems, the integration of
all the modules is the critical part. The end-users must understanding the sequence of
operations, how one module interact with the others and what are the restrictions in operation
in terms of priority so as to establish proper checks at all levels in the process. The coordination
among project members for different modules is very essential for smooth and
successful implementation.
(b) An Executive Information System (EIS) is special type MIS meant for top management of an
organization. In other words, it is a Decision Support System (DSS) for Executives. Executive
decisions are of three types – strategic planning, tactical planning and ‘fire-fighting’. According
to CIMA – An Executive Information System (EIS) is a set of procedure designed to allow
senior managers to gather and evaluate information relating to the organization and its
environment.
Naturally, the EIS takes care of the requirement of information depending upon the type of
decisions taken at different levels of managers in an organization. In fact, EIS acts as a tool
specially designed for different executives to feed their information need in useful formats.
Group-II : Paper-9 : Operation Management and Information Systems 105
A manager can navigate a particular format with some amount of computer skill. The EIS is
not only limited to internal data source rather facilities to easy access to common sources
of external data is also arranged.
Following are the special features of an EIS :
• It a specially designed tool to feed executives information need.
• It is an easy - to - use and screen based software .
• It provides the executives to facilities of on-line analysis tools like time series analysis,
regression analysis etc.
• It is not limited to internal data only. Access to external sources of data is also provided.
• It provides the facilities to connect to internet
• Information is presented in summary format
• It is a comprehensive information system and work in conjunction with DSS.
For an Executive Information System, information requirement varies widely according to
the requirement to understand the impact of different variables on the issue. For example,
for decision of pricing of a product, information requirement may be summed up as follows :
• Recent history of price changes
• Demand for the product
• Graph showing the relationship between demand and price exhibited by recent results
• Effect of demand of changing price over time
• Prices of substitute products
• Price of similar products
• Cost of sales etc.
(c) The data warehousing is the concept of data integration by way specialized data storage
and retrieval technique. The core of data warehousing is multi-dimensional databases. The
basic objective of data warehousing is to give right kind of expert analysis of data and feed
the decision makers with right kind of information for effective decision to run the business
efficiently.
The need for data warehousing has come from increased competition and demand for more
and accurate information for precise decision making. Data warehousing can translate the
data in common format and store them scientifically for faster access. Combining the related
data is the crux in the approach of data warehousing. Thus, database design has a definite
key role in making the storage efficient. Providing sensible information is only possible through
analysis of related data.
Steps involved :
• Development of hardware and software infrastructure
• Building sound corporate database
• Establishment of communication network
• Managing smooth data flow from multiple operational points
• Building proper check and security measures from misuse
106 Revisionary Test Paper (Revised Syllabus-2008)
Critical factors involved in data warehousing:
• Heterogeneous data set and their translation in common format
• Organization of database
• Capability of software tool
• Judgement on transactional period for storage of data
Advantages:
• Effective, efficient and convenient data storage
• Elimination of duplication
• Lower cost of storage
• Faster navigation through related information
• Reliable data
• Consistency in reporting
• Better decision making
Strategic use of data warehousing in different business environments:
• Customer Service
• Sales Promotion
• Market analysis of new products
• Trend Analysis
• Inventory Control
• Sales decisions
(d) Artificial Intelligence refers to behaviour of computer system which seems to be intelligence
of the computer itself. As we know, the computer does not have power to act on its own,
the intelligent solutions from a computer system is termed to be Artificial Intelligence. In
fact, this phenomena is exhibited by a computer system out of the expertise of the software
which has the capability to interpret the problem situation and use the knowledge base to
evolve intelligent solutions. The artificial intelligence is closely associated with expert system.
It is only the expert system which can exhibit artificial intelligence.
Q12. Differentiate Between :
(a) Ring network and Star network
(b) Client-Server Model and Peer- to -Peer Model
(c) MODEM and Multiplexer
(d) The Internet and the Intranet
(e) Intranet and Extranet
(f) Internet and World Wide Web.
Answer 12.
(a) Ring network and Star network
Ring network and Star network: In Ring network, the network cable passes from one node
to another until all nodes are connected in the form of a loop or ring. There is a direct pointto-
point link between two neighboring nodes. These links are unidirectional which ensures
that transmission by a node traverses the whole ring and comes back to the node, which
made the transmission. Ring networks offer high performance for a small number of
workstations or for larger networks where each station has a similar workload. These
networks can span longer distances than other types of networks and are easily extendable.
Group-II : Paper-9 : Operation Management and Information Systems 107
1. In this model, number of computers,
known as clients are connected to a single
host computer known as server.
In this model, all the computers are
interconnected with each other. There is no
concept of server and clients. All computers
behave as server as well as clients.
2. It uses a dedicated server which provides
various services to clients like hardware,
software and data access. Different types
of servers can be File, Fax, Print or Database
server.
It uses non-dedicated server. Non-dedicated
server can also be used as a node for data
entry, processing and output operations.
3. Clients can share disk storage and printers
attached with the server.
All computers can share the data/resources
of each other.
4. It is suitable for large organization having
large number of nodes.
It is suitable in small organization having less
number of nodes upto ten.
5. Data transfer speed is more. Data transfer speed is less which decreases
even further with the increase in number of
computers.
6. Failure of server results in break-down of
entire network.
Failure of one computer will not affect the
working of other, only the data stored on the
faulty computer will not be accessible to other
computers.
7. Server can not be used for data entry/result
purposes, hence it can be said that all the
computers are not fully employed.
All the computers are fully employed.
8. Clients are required to be connected with
server in a particular structure like Star
Network.
Computers can be connected at any
convenient point in the network like Ring
Network.
9. Clients can be dumb terminal or Intelligent
terminals.
All computers are intelligent terminals.
10. This architecture is employed where data
security is of prime importance.
This architecture is used when security is not
a bigger issue.
The Star network structure, on the other hand, is very popular for LANs. In this topology,
the network is characterized by communication channels emanating from centralized
computer system. That is, processing nodes in a star network interconnect directly with a
central system. Each terminal, small computer, or large mainframe can communicate only
with the central site and not with other nodes in the network. If it is desired to transmit
information from one node to another, it can be done only by sending the details to the
central node, which in turn sends them to the destination. A star network is particularly
appropriate for organizations that require a centralized data base or a centralized processing
facility. In a Star network, it is easy to add new nodes and also remove nodes. A node
failure does not bring down the entire network. It is easier to diagnose network problem
through a central hub.
b) Client-Server Model and Peer- to-Peer Model
Client-Server model Peer-to-Peer model
108 Revisionary Test Paper (Revised Syllabus-2008)
(c) MODEM and Multiplexer:
Modem stands for Modulator/Demodulator. It is a device that converts a digital computer
signal into an analog telephone signal (i.e. it modulates the signal) and converts an analog
telephone signal into a digital computer signal (i.e. it demodulates the signal) in a data
communication system. Modems are required to telecommunicate computer data with
ordinary telephone lines because computer data is in digital form but telephone lines are
analog. Modems can be categorized into internal and external modems.
Multiplexer is a device that enables several devices to share one communication line. A
number of devices are connected to the multiplexer. Multiplexer scans each device to collect
and transmit data on a single line to the CPU. It also communicates transmission from the
CPU to the appropriate terminal linked to the multiplexer. Devices connected to the multiplexer
are polled and periodically asked whether there is any data to transmit. Data collected from
all terminals are transmitted on same communication line.
(d) The Internet and the Intranet:
The Internet is a global network of computer networks that was initiated in the year 1960’s
by a team of scientists under a U.S. Government contract. There are approximately 1,40,000
small networks in more than 200 countries connected through Internet. These networks
are formed by various educational, commercial, Government, non-profit and military
organizations. These networks are individually owned and operated that are all interconnected.
Internet is a combination of number of computers, linked together, sharing same resources.
There are thousands of databases containing information of all sorts in addition to the facilities
like e-mail, chatting, games, message boards and free software.
Networks comprise addressable devices or nodes (computers) connected by communication
channels. Any node can transmit a message to any other node, along with communication
channels, via the intermediate nodes. Internet uses are many; some of them are given
below:
(a) Communication – It could be on-line or off -line.
(b) Data Retrieval – As large number of databases exists on Internet, one can make use of
data according to his/her requirements.
(c) Data Publishing – Data publishing is a new opportunity that Internet has made possible.
The information can be forwarded to any one.
The intranet, on the other hand, is a type of information system that facilitates communication
within the organization, among widely dispersed departments, divisions and regional locations.
Intranet connects people together with Internet technology using Web Browsers, Web Servers
and Data Warehouses in a single view. Within an Intranet, access to all information,
applications and data can be made available through the same browser. We can perform
the following works :
• Easily accessible information.
• Reduced information searching time.
• Share and reuse of tools and information.
• Reduced set up and update time.
• Reduced documentation cost etc.
• Several applications of Intranet include :
Group-II : Paper-9 : Operation Management and Information Systems 109
• Supplier management.
• Inventory management.
• Distribution management.
• Channel management.
(e) Intranet and Extranet:
Intranet is a type of information system that facilitates communication within the organization,
among widely dispersed departments, divisions and regional locations. Intranets connect
people together with Internet technology, using web browsers, web servers and data
warehouses in a single view. With an Intranet, access to all information, applications and
data can be made available through the same browser. The objective is to organise each
individual’s desktop with minimal cost, time and effort to be more productive, cost efficient,
timely and competitive.
An Extranet is an extension of an Intranet that makes the latter accessible to outside
companies or individuals with or without an Intranet. It is also defined as a collaborative
Internet connection with other companies and business partners. Parts of an Intranet are
made available to customers or business partners for specific applications. The Extranet is
thus an extended Intranet, which isolates business communication from the Internet through
secure solutions. Extranets provide the privacy and security of an Intranet while retaining
the global reach of the Internet. An Extranet extends the Intranet from one location to
another across the Internet by securing data flows using cryptography and authorization
procedures, to another Intranet of a business partner.
(f) Internet and World Wide Web:
Internet is a global network of computer networks formed by various educational, commercial,
Government, non-profit and military organizations linked together, sharing same resources.
They exchange data and information by packet switching and using the standard ‘Internet
Protocol’ (IP). Besides data exchange, it also provides the facilities like e-mail, chatting,
games, message boards, etc.
World Wide Web (WWW) is a component of the Internet that provides access to large
amounts of information located on many different servers. It also provides access to many
of the services available on the Internet. It contains collection of interconnected documents
and other resources which are linked through hyperlinks and URLs.
Q13. Explain the working principle of Electronic Data Interchange (EDI).
Answer 13.
Electronic Data Interchange (EDI): EDI is the transmission of business information in standard
format between computers of independent organizations. There is no need to change the database
structure by the companies for implementation of EDI. However, EDI software is required to be
developed for translating the format used by one organization to the format being used by another
organizations. So EDI is computer-to-computer communication using a standard data format to
exchange business information electronically between independent organizations.
Working Principle of EDI – EDI is the electronic exchange of business documents such as invoices,
purchase orders, shipping notices etc. EDI is a three step process :
1. First of all, sender data is converted into standard format as defined by EDI translation
software.
110 Revisionary Test Paper (Revised Syllabus-2008)
2. Data in standard format is transferred to the receiver using communication lines.
3. Finally, standard format data is converted according to the format of receiver data base
files.
EDI consists of three components:
(i) Communication - To make EDI work, one needs communication software, translation software
and access to standards. Communication software moves data from one point to another,
flags the start and end of the document. Translation software helps the user to build a map
and shows him how the data fields from his application corresponds to the elements of EDI
standards. It also converts data back and forth between the application format and the EDI
format.
(ii) Mapping - To build a map, the user first selects the EDI standard for the kind of data he
wants to transmit. Usually the trading partner tells about the kind of standards to be used.
Next, he edits out parts of the standards, which do not apply, to his application. Next, he
imports a file that defines the fields in his application, and finally he makes the map to show
where the data required by the EDI standards is located in his application. Once the map is
built, the translator will refer to it during EDI processing every time a transaction of that
type is sent or received.
(iii) Profile - The last step is to write a partner profile that tells the system where to send each
transaction and how to handle errors or exceptions. Whereas the user needs a unique map
for every kind of documents he exchanges with a partner, he should only have to define
partner information once.
Q14. Explain the concept of communication protocols.
Answer 14.
Communication protocols are sets of rules or conventions that must be adhered to by both the
communicating parties to ensure that the information being exchanged between them is received
and interpreted correctly. A protocol defines the following three aspects of digital communication.
(i) Syntax – The format of data being exchanged, character set used, type of error correction
used, type of encoding scheme being used.
(ii) Semantics – Type and order of messages used to ensure reliable and error-free information
transfer.
(iii) Timing – Define data rate selection and correct timing for various events during data transfer.
Communication protocols are defined in layers, the first of which is the physical layer or the
manner in which node in a network are connected to one another. Both the network software and
network-interface card have to adhere to a network protocol. The RS-232 C connector is the
standard for some communication protocols. Subsequent layers, the number of which vary between
protocols, describe how messages are packaged for transmission, how messages are routed through
network, security procedures and the manner in which messages are displayed.
A number of different protocol codes are in use. For example, X.12 is the standard for electronic
data interchange (EDI) X.75 is used for interconnection between networks of different countries,
and XMODEM is used for uploading and downloading files. The set of most common protocols
used on the Internet is called TCP/IP.
Group-II : Paper-9 : Operation Management and Information Systems 111
Q15. Which areas of DBMS should be addressed while maintaining a database? Explain.
Answer 15.
Following five areas of DBMS managements are be considered when trying to maintain a welltuned
database:
(i) Installation of database
Correct installation of the DBMS product.
Ensuring that adequate file space is available.
Proper allocation of disc space for database.
Allocation of data files in standard sizes for I/O balancing.
(ii) Memory Usage – One should know about following memory management issues:
How the DBMS uses main memory ?
What buffers are being used ?
What needs the programs in main memory have?
Knowledge of above issues can help in efficient usage of memory.
(iii) Input / Output (I/O) contention
Achieving maximum I/O performance is one of the most important aspects of tuning.
Understanding how data are accessed by end-users is critical to I/O contention.
Simultaneous or separate use of input and / or output devices.
Clock speed of CPU requires more time management of I/O.
Spooling/Buffering etc. can be used.
Knowledge of how many and how frequently data are accessed, concurrently used
database objects need to be striped across disks to reduce I/O contention.
(iv) CPU Usage
Multi programming and multi processing improve performance in query processing
Monitoring CPU load.
Mixture of online/back ground processing need to be adjusted.
Mark jobs that can be processed in run off period to unload the machine during peak
working hours.
Q. 16) Explain the terms:
i) Firewall
ii) Disaster Recovery
iii) Risk in information systems
Answer 16.
(i) Firewalls offer an effective system to protect access by unauthorized user from outside.
The main feature of firewall is packet-filtering router so that vital information does not pass
to any unauthorized intruder, even if he manages get access to the network system. It is a
112 Revisionary Test Paper (Revised Syllabus-2008)
system of security in the network with the help of hardware and software. A software
checks all incoming and outgoing internet traffics. The firewall routes the massages to a
safe area to avoid any danger in the in forward transmission of messages. The screening by
firewall software may delay the transmission process but ensures proper security.
Limitations of Firewall
• Passing on information by internal employees through internet can not be checked.
• Firewall can not protect the system from virus.
(ii) Disaster Recovery : Disaster means sudden great misfortunate happening which can not be
prevented. Disaster may be of two types – i) Natural like flood, earthquake, hurricane
damage etc. ii) Technological like failure of computer, electrical fire etc.
The damage under disaster is generally enormous. The question of recovery in case of disaster
comes from data. Data may be categorized as critical, vital, sensitive and non-critical. Recover
plan may be devised accordingly to given priority of recovery of data of different importance.
Emergency Action : In the first stage the notification of damage is to be given to the appropriate
agency/authority like fire service, police, insurance company etc. Then following action may be
taken depending in the situation to save personnel, equipment, data etc like:
• sounding alarm bell
• use of fire extinguisher
• saving the back-up of software, data etc.
Recovery Action: There needs an advanced planning for recovery of data under disaster. Generally,
the disaster recovery planning is done by a Recovery Committee and execution of recovery
programmes is done under its supervision and control. These are:
• Backup Application software and backup of databases at a regular interval to be preserved in
some other location.
• Mirror imaging of disk.
• Selection of alternative computer system.
• Restoration of application software and databases in the new computer system.
• Critical evaluation of performance of the application software.
• Assessment of loss of databases.
• Plan for recovery of data loss etc.
(iii) Risk is the probability of happening something adverse. An information is vulnerable to many
risk factors which are categorized below.
Risk Management is a process of assessing risk and reducing it to an acceptable level. Steps
involved in it are:
• Understanding the sources and causes of risk.
• Collection of data related to risk to analyse their nature and frequency.
• Evaluation of magnitude of risk.
• Develop policy to minimize the risk.
• Develop methodology to prevent their occurrence.
• Implementation of the methodology.
Group-II : Paper-9 : Operation Management and Information Systems 113
Q17. Define :
i) Audit Charter
ii) Audit Trail
iii) Outsourcing in Information System
Answer 17.
i) There is a need for an audit charter for properly organising the information system audit
function within an organisation. An audit charter covers legitimacy and role of the internal
audit function inclusive of information system audit function and deals with three issues viz.
1. Place of audit function within the organisation and its role in contributing towards fulfilment
of organisational goals.
2. Authority of the audit function to gain access to records, facilities and personnel including
Board of Director’s audit committee or to the Board itself.
3. Responsibility of the audit function to advice the management about the quality of
attainment of the four objectives viz. asset safeguarding, data integrity, system
effectiveness and system efficiency.
The rights and responsibilities of both the internal audit function and the information systems
audit function within an organisation should be clearly defined to prevent disputes over the
issue and ensure effectiveness and efficiency of the audit function. It is also to be determined
whether information system audit should have line function or staff function after considering
the arguments for each strategy in the overall organisational perspective. Another issue
concerns about centralisation as against decentralisation. This issue is to be dealt with also
in the case of external auditors. Much depends on whether the organizational function is
centralised or decentralised.
ii) Audit trail refers to a system of designing of an information system in a manner that the
historic data and information at any processing stage may be traced to verify the origin,
correctness, authenticity, flow and destination including the stages of security procedures
for establishment of integrity of data and information.
iii) Outsourcing may be defined as the use of parties, external to the organisation, to provide
goods or services to the organisation. Outsourcing in today’s economic environment is
considered as an important means of improving an organisation’s competitiveness and
profitability. By outsourcing an organisation can pay more attention to its core competitiveness
and take advantage of other organisation’s core competencies.
Any organisational function may be a point of consideration for outsourcing e.g. legal services,
security, any manufacturing process, supply of components for the products, and even the
information system itself.
The reasons for outsourcing of information system function are:
1. Exercising greater control over the information system function if it is outsourced e.g. vendors
being more responsive to user needs, sharing economies of scale achieved by the vendor
and restricted consumption of information system resources which are no longer free.
2. Innovative approach because of access to new technology and expertise expected from the
vendor.
114 Revisionary Test Paper (Revised Syllabus-2008)
There is some preparatory work before a decision on outsourcing of information system services
can be taken. Such work is of the following nature:
1. It should be determined what part of information system activities can be outsourced, what
are strategic to the organisation, and whether suitable (expert, dependable, financially viable
and reliable) vendors exist.
2. Terms and conditions of the contract including termination clause for outsourcing should be
determined incorporating scope of work, audit rights, performance criteria, responsibilities
etc.
3. Monitoring compliance with the terms and conditions.
4. Impact on the organisation.
5. Procedures for outsourcing disaster recovery control.
