MANAGEMENT INFORMATION SYSTEMS
UNIT-1
Section-A
1. Write a short note about management information system (MIS).
DEFINITION:
Management information system is a system consisting of people, machines, procedures,
databases and data models, as its elements. The system gathers data from the internal and
external sources of an organisation.
MEANING:
Management information system is an acronym of three words, viz., Management,
information, system .in order to fully understand the term MIS, let us try to understand these
three words.
Management:
Management is the art of getting things done through and with the people in formally
organised groups.
Managerial function:
Planning
Organising
Staffing
Directing and
Controlling

Management hierarchy:
Information:
Information is data that is processed and is presented in a form which assists decision-
making.it may contain an element of surprise, reduce uncertainty or provoke a manager to
initiate an action.
Data usually take the form of historical records. In contrast to information, raw data
may not be able to surprise us, may not be organised and may not add anything to our
knowledge.
DATA-------→PROCESSING-------→INFORMATION
System:
The term system is the most loosely held term in management literature because of its
use in different contexts. However, a system may be defined as a set of elements which are
joined together to achieve a common objective. The elements are interrelated and
interdependent.
The set of elements for a system may be understood us input, process and output. A
system has one are multiple inputs; these inputs are processed through a transformation
process to convert these input into outputs. The three elements of a system are
INPUT------→PROCESS--------→OUTPUT
strategic
management(top
management)
management
control(middle
management)
operational control(bottom
management)

2. What are the various functions of information systems?
One of the mostly widely used bases for organising activities in almost every
organisation is the business function. Business activities are grouped around functions
such as production, marketing, finance and personnel etc... Resulting in the respective
department or an area of the business organisation. These departments or functional areas
are commonly known as the functional areas of business.
There is no standard classification of such sub-system in an organisation, but a
typical set of functions in a manufacturing organisation includes:
Production
Marketing
Finance and accounting
Materials and
Personnel systems
Production:
Production planning and control
Engineering standards
Quality control
R & D etc
Marketing:
Sales order
Forecasting
Sales analysis
Billing
Distribution
Stock availability
Sales quota control
Pricing
Product promotion

Finance and accounting:
Financial planning
Budgeting
Cost accounting
Asset accounting
Accounts receivable
Payroll
Accounts payable, etc...
Materials:
Material planning
Bill of material
Cost estimate
Warehousing planning etc...
Personnel:
Employee recruitment
Employee selection
Employee development
Employee transfers
Employee retirements etc...
3. Discuss about information system resources.
In information system includes four major resources, hardware, software, people
and data. Let’s briefly discuss some basic concepts and examples of how these resources
contributes to the information processing activities of information system.
Hardware---- it includes all physical devices
Software-----it includes all set of information processing
instructions.
People -------people are required for the operation of all
information systems. These people resources include specialists
and end users.

Data-----data is more than the raw material of information
systems. The concepts of data resources have been broadened by
managers and information system professionals.
4. List out the different types of information.
Information could be classified on the basis of the purpose for which it is
utilised, into three main categories:
 Strategic information-----it is required by the managers at the strategic level
of management for the formulation of organisational strategies.
 Tactical information -----information in this category is used in short term
planning and is of use at management control level.
 Operational information-----it applies to short periods which may vary from
an hour to a few days.
5. Discuss about need for in information system.
Meeting global challenges
Capturing opportunities in marketplace
Supporting corporate strategy
Linking departments whose functions are different
Enhancing worker productivity
Increase in quality of goods and services
Section-B
1. List and explain the classification of information system.
The discipline of MIS is in its evolutionary stage. MIS is a concept, which is a
matter of degree rather than an absolute one. The classifications of information system are
Transaction processing system.
Management information system.
Decision support system.
Executive support system.
Office automation system.
Business expert system.

Transaction processing system:
It represents the automation of the fundamental, routine process used to support
business operations. It does not provide any information to the user for his/her decision
making. Previously Transaction processing system was known as MIS. Prior to computers,
data processing was performed manually or with simple machines.
(INPUT) DATA--------→PROCESSING--------→DATA (OUTPUT)
Management information system:
MIS is an information system which process data and converts it into information.
A MIS uses TPS for its data inputs. The information generated by the information system
may be used for control of operations, strategic and long range planning, short range
planning, management control and other managerial problem solving.
It has some functional business areas. They are
Marketing
Production
Human resources
Finance
Accounting etc...
TPS------→DATA------→INPUT------→PROCESSING-------→OUTPUT-----
---→INFORMATION
Decision support system:
The Decision support system (DSS) is an information system application that assist
decision making. Decision support systems tend to be designed primarily to serve
management control level and strategic planning level managers.
The data in the database typically is a combination of master files (internal
corporate data) and from external sources.

Database←-------------→model base

Executive support system:
Executive support system (ESS) is an extension of the management information
system which is a special kind of DSS. An ESS is specially tailored for the use of chief
executive of an organisation to support his decision making.
An ESS is designed to cater to the information needs of a chief executive keeping
in view not only his requirements but also taking into account his personality and style of
functioning etc.,
Office automation system:
Office automation refers to the application of computer and communication
technology to office functions. Office automation systems are meant to improve the
productivity of managers at various level of management by providing secretarial assistance
and better communication facilities. Office automation systems are the combination of
hardware, software and people in information systems, that process office transactions and
support office activities at all levels of the organisation.
These systems include a wide range of support facilities, which include word
processing, electronic filing, electronic mail, message switching, data storage, data and voice
communication etc...
In the first category, the following is a list of activities.
Typing
Mailing
Scheduling of meetings and conferences
Calendar keeping and
Retrieving documents

In the secondary category,
Conferencing
Production of information
Controlling performance
Business expert system:
Business expert system (BES) is a knowledge based information system that uses its
knowledge about a specific, complex application area to act as an expert. This system is
one of the knowledge based information system.
Expert system provides decision support to managers in the form of advice from an
expert in a specific problem area. Expert systems find application in diverse areas,
ranging from medical, engineering and business.

2. Discuss about cost benefit analysis.
Every legitimate solution will have some advantages is benefits and some
disadvantages or costs. These advantages and disadvantages are identified when each
alternative solution is evaluated. This process is typically called cost/benefit analysis.
Examples: ↑ in sales or profits.
↓ in operating costs.
↓ in required investment
Selecting the best solution:
Once all alternative solutions have been evaluated the process of selections the best
solution can begin. Alternative solutions can be compared to each other because they have
been evaluated using the same criteria. It is possible that to decide to select the best solution
to the problem.

Implementing a solution:
Once a solution has been selected it must be implemented. An implementation plan
may be developed. An implementation plan specifies the activities, resources and timing
needed for proper implementation.
Post implementation review:
The final step of the system approach recognized that an implemented solution can
fail to solve the problem for which it was developed. The results of implementing a solution
should be monitored and evaluated. This is called a post implementation review process.
Global business strategies:
MNC is a firm that operates across products, markets, nations and cultures. It consists
of the parent company and a group of subsidiaries. They are geographically disresed and each
one may have its own unique goals, policies and procedures.
Multinational strategies:
It was a type of “hands off” strategy in which the parent allowed the subsidiaries to
develop their own products and practise. The information flows are primarily from the
subsidiaries to the parent in the form of financial reports.
Global strategy and international strategy is also comes under cost/benefit analysis.
3. Components /resources of information system.
An information system depends on the resources of people, hardware, software,
data and networks to perform input, processing, output, storage and control activities that
convert data resources into information.
IS consists of 5 major resources:
People resources:
People are the essential ingredient for the successful operation of all information
systems. This people resource includes:
End users are also called users or clients are people who use an
information system or the information it produces. They can be
customers, salespersons, engineers etc... Most of us are IS end
users.

IS SPECIALISTS are people who develop and operate
information system. They include system analysis, software
developers, system operators and other managerial, technical and
clerical IS personnel.
Hardware resources:
It includes all physical devices and materials used in information processing.
Examples of hardware in computer based information system are:
Computer system which consists of central processing units
containing microprocessors and a variety of interconnected
peripheral devices. Example: handheld, laptop, midrange computer
systems and large mainframe computer systems.
Computer peripherals which are devices such as a keyboard or
electronic mouse for input of data and commands a video screen or
printer for output of information and magnetic or optical disks for
storage of data resources.
Software resources:
It includes all set of information processing instructions. It includes not
only the set of operating instructions called programs. Examples are
System software such as an operating system program which
controls and supports the operations of computer system.
Application software which are programs that direct processing for
a particular use of computers by end users. Example sales analysis
program, a payroll program and a word processing system.
Data resources:
Data resources of information systems are typically organised, stored and
accessed by a variety of data resources mgt technologies into:
Database that hold processed and organised data.
Knowledge bases the hold knowledge in variety of forms such as facts,
rules, and case.

Network resources:
Telecommunications technologies and networks like the internet, intranets and
extranets. The concept of network resources emphasizes that communications technologies
and networks are a fundamentals resource component of all information systems. Network
resources include:
Communications media is includes twisted pairs wire, coaxial and fiber
optic cables and microwave, cellular and satellite wireless technologies.
Network infrastructure this generic category emphasizes that many
hardware, software and data technologies are needed to support the
operation and use of a communication networks.
4. Write about the fundamentals and dimensions of information system.
It shows the 3 major roles of the business applications of information systems.
Example: consider a retail store as a good example of how these three fundamental roles can
be implemented by a business.
 Support business processes and operations
 Support business decision making
 Support strategies for competitive advantage
Support business processes and operations:
As a consumer you have to deal regularly with the information systems that support
the business processes and operations at the many retail stores where you shop. Example:
most retail stores now use computer based information systems help them record customer
purchase, keep track of inventory, pay employees, buy new merchandise and evaluate sales
trends.
Support business decision making:
IS also help store managers and other business professionals make better decisions
and attempt to gain a competitive advantage.

Support strategies for competitive advantage:
Gaining a strategic advantage over competitors requires innovative use of
information technology.
DIMENSIONS:
The major dimensions of information systems are:
1. Organisation: IS are integral parts of organisations. The key elements of an
organisation are its:
People
Structure
Business processes
Politics
Culture
2. Management: management’s job is to make sense out of many situations faced by
organisations, make decisions and formulated action plans to solve organisational
problems.
3. Technology: information technology is one of many tools managers use to cope with
change in various resources of technology involved in IS are:
Computer hardware
Computer software
Data management technology
Networking and telecommunication technology

UNIT -2
Section-A
1. Discuss about the marketing information system (MKIS).
The role of MKIS is to assess the marketing managers information needs then
develop the framework for collecting information and distribute the information
gathered to the end users in time. The marketing information system is generally
carried out marketing need analysis, planning, and implementation and control
functions of marketing managers.
The needed information is developed through internal company records,
marketing intelligence activities, marketing research and marketing decision support
analysis.
Different parts of MKIS:
accounting information system
marketing , sales and customer services
sales force automation
saves company labours hours and telephone expenses
capture customer data
response time to customer inquiries
market research and intelligence information system
customer research
market research
competitor intelligence
Competitor’s products.
“ Operating strengths and weaknesses.
“ Customer service level and customer
policies.
“ New product line.

2. Discuss manufacturing information system.
Manufacturing information system is a complete set of tool for managing the
flow of manufacturing production data throughout the enterprise. This IS was designed to
provide tools for both IT and operations personnel who would deliver services to anyone in
the plant.
Manufacturing consists of many different disciplinary areas including product
engineering, facility design and scheduling, fabrications, and quality control management.
Each of them can be dramatically improved by using information systems.
A manufacturing system takes material, equipment, data management and
information systems technology as the input and uses manufacturing and information
processes to generate better final product as output. The manufacturing designed around the
transaction process of raw materials into usable components or materials. These systems are
value added processes such as materials processing or support systems such as scheduling.
3. Discuss business information system.
Business information system in marketing, manufacturing, and human resources
with a special emphasis on computer integrated manufacturing. It describes the most widely
used types of accounting information systems as well as information needed for the effective
financial management of a firm.
Functional Business information systems:
Marketing
Production/operations
Accounting
Finance
Human resource management
4. Discuss accounting information system.
Accounting information system is the part of organisations information system.
The information system processes a mixture of quantitative and qualitative data but the
accounting information system focuses almost entirely on processing quantitative data. The

accounting system and information system must work together in an effective and efficient
way.
Accounting information system provide efficient delivery of information needed
to perform necessary accounting work and to assist in delivery of accurate and informative
data to users especially those who are not familiar with the accounting and financial reporting
areas itself. A high value of data processing characterizes these applications. Data processing
consists of 4 major tasks- data gathering, data manipulation, data storage, and document
preparation.
Section-B
1. List and explain in detailed about transaction processing system?
Transaction processing system:
Transaction processing systems are information system that process data resulting
from the occurrence of business transactions. Transactions are events that occur as part of
doing business such as sales, purchase, deposits, withdrawals, refunds and payments.
For example:
The data generated whenever the business sells something to a customer on credit.
Data about the customer, product, salesperson, and store and so on must be captured and
processed. This in turn causes additional transactions such as credit checks, customer billing,
inventory changes, and increases in accounts receivable balances, which generate even more
data. Thus, transaction processing activities are needed to capture and process such data, or
the operations of a business world grind to a halt. Therefore, transaction processing systems
play a vital role in supporting the operations of an organisation.
The Transaction processing cycle:
Transaction processing systems capture and process data describing business
transactions. Transaction processing system has five stages of cycle. They are
Data entry activities
Transaction processing activities
File and database processing

Document and report generation
Inquiry processing activities
The data entry process:
The input activity in transaction processing systems involves a data
process. In this process data is captured or collected by recording,
coding and editing activities.
Data may be converted to a form that can be entered into a computer
system.
It has always been a problem getting data into computers accurately and
quickly enough to match their awesome processing speeds.
These methods are more efficient and reliable and are known as source
data automation.
Traditional data entry:
Traditional methods of data entry typically rely on the end users of an
information system to capture data on source document such as
purchase order, payroll time sheets and sales order forms. The source
documents are subjected to one of the following additional data entry
activities.
The data is converted into a machine – readable medium, such as
magnetic tape or magnetic disks. Typically this means using such
devices as key to tape machine and key to disk system.
The data from source documents could alternatively be directly entered
into a computer system using a direct input device without the use of
machine readable media.
Source of data automation:
 The use of automated methods of data entry is known as source data
automation several methods have been developed to accomplish this
automation though very few completely automate the data entry
process.

They are all based on trying to reduce or eliminate many of the activities,
people and data media required by traditional data entry methods.
Batch processing:
Transaction processing system process data two basic ways:
Batch processing where transaction data is accumulated over a period
of time and processed periodically.
Real time processing where data is processed immediately after a
transaction occurs.
Transactions processing systems still make heavy use to batch processing.
Batch processing activities:
In a batch processing system transaction data is accumulated over a period of time and
processed periodically. Batch processing usually involves.
Gathering source documents originated by business transactions such a sales orders
and invoices into groups called batches.
Recording transactions data on an input medium such as magnetic disk or magnetic
tape.
Sorting the transactions in a transaction file in the same sequence as the records in a
sequential master file.
Processing transaction data and creating an updated master file and a variety of
documents and reports.
Real time processing:
It process transaction data immediately after they are generated and
can provide immediate output to end users.
Data is fed directly into the computer system from online terminals
without being stores and it is always stored online in direct access
files.
Files and database are always upto date since they are updated
whenever date is originated regardless of its frequency.

Real time processing depends as telecommunications networks of
online terminals and computers.
Conclusion:
Transaction processing systems are operations information systems that process
data resulting from business transactions. They involve the basic activities of data entry,
transaction processing, file and database etc.
2. Discuss about financial information system.
Financial information system is a sub system of organisational management
information system. This sub system supports the decision making process of financial
functions at the level of an organisation.
A brief description of each of the financial decisions that a financial manager has
to take is given below.
Capital budgeting decision----in this decision funds are allocated to long term asset
which would yield benefits in the future. Example: funds allocated for land, building,
machinery, etc...
Financial decision----the financial manager has to decide about the proportion of
equity and debt capital.
Dividend decision-----this decision relates to the dividend policy of the organisation.
A decision whether the organisation should distribute all profits or retain them or
distribute a portion and retain the balance has to be taken by the financial managers.
Current asset management-----in order to safeguard the org against liquidity or
insolvency current assets of the organisation are also required to be efficiently
managed.
3. Discuss about human resources information system.
This functional information system supports the functions of human resource
management of an organisation. The function involves:
Manpower planning:
It is about deciding the present and future needs of manpower in the
organisation.

Staffing:
This function includes recruitment, selection and placement of employees.
Recruitment refers to attracting qualified and competent people for different jobs.
Training and development:
The need to train and develop the employees is felt due to
A gap between the job requirements and competence of the employee.
The need to develop lower level managers to assume higher level
responsibility when required.
Performance evaluation:
This task is concerned with evaluating employee performance at work in terms
of pre determined standards and norms. Evaluation or performance appraisal
includes the formulation of performance appraisal plans, development of appraisal
techniques and programmes etc...
Separation activities:
The employee employer relations may come to an end due to the resignation
of an employee, layoff, death or retirement. HRM besides the above mentioned
functions is also responsible for the wages and salary administration, sustaining and
maintaining the work force in the organisation and maintaining of healthy and
peaceful labour management relations. It contains 3 function flow of human resource
information system.
Transaction data-----is a basis for various types of output
information or analysis. The data includes employee number, name,
qualification, experience, joining data etc... Categories and grades of
posting and daily performance etc...
Environmental data----includes data about the availability of
personnel, trends in the labour force, competition, market offering to the
employees, government and labour laws etc...
Organisational plans------also provide an important input in
human resource information system, on the basis of which future planning
for recruitment, job assignment, etc...

4. Discuss accounting information system.
Accounting information system is the part of organisations information system.
The information system processes a mixture of quantitative and qualitative data but the
accounting information system focuses almost entirely on processing quantitative data. The
accounting system and information system must work together in an effective and efficient
way.
Accounting information system provide efficient delivery of information needed
to perform necessary accounting work and to assist in delivery of accurate and informative
data to users especially those who are not familiar with the accounting and financial reporting
areas itself. A high value of data processing characterizes these applications. Data processing
consists of 4 major tasks- data gathering, data manipulation, data storage, and document
preparation.
Characteristics of accounting information system:
Performs necessary task
Adheres to relatively standardized procedures
Handles detailed data
Has a primarily historical focus
Provides minimal problem solving information
Sources of accounting information system:
Procedures manual
Management accounts / balance sheets
Financial data
Accounting policies
Tax details
Working capital

Types of accounting information system:
 General ledger system: this module helps organisations leverage the GL
processing speeds available streamline accounting processes and reduce the
period end close cycle.
 Asset management: this module help streamline tracking, depreciation and
maintenance scheduling of asset improve productivity with easier access to
critical information derive maximum tax benefits and minimize risk of loss or
damage to capital assets. It maintains an inventory of the company’s long
term assets.
 Order entry system: it captures and manages different kinds of data relating
to a transaction such as number of units sold customer billing.
 Account receivable and payable system: this module helps organisations
bill customers automatically from any sales channel, streamline accounts
receivables processing and automate the invoicing process.
 Inventory control system: it captures processes and manages all issues
related to the company’s inventory such as items in inventory, inventory cost,
lost items and damages items.
 Payroll system: it captures and processes data related to salaries including
taxes, other deductions, benefits, overtime and other related data.
 Cash management: this module helps organisations forecast cash flows in
any currency and in multiple time periods, streamline the reconciliation
process, monitor exceptions and fraud and manage the cash cycle efficiently
with control.

UNIT -3
Section-A
1. Discuss about components of DSS?
Following are the components of the DSS:
Data management sub system: Data management sub system includes a database that
contains relevant data for the situation and is managed by software called Database
management system (DBMS).
Data management sub system is composed of the following elements:
DSS database
Database management system
Data directory
Query facility
Model management sub system: this is a software packages that includes financial,
statistical, management science or quantitative models that provide the systems analytical
capabilities and appropriate software management
Model management sub system is composed of the following elements:
Model
Model base management system
Modelling language
Model directory
Model execution, integration and command processor.
User interface sub system: the user communicates with and commands the DSS through the
sub system. The user is considered part of the system.
Knowledge base management sub system: this sub system can support any of the other sub
systems or act as an independent component.

1. Discuss the role of DSS in business?
The roles of DSS are as follows:
What if analysis: in what if analysis an end user makes changes to variables or
relationships among variables and observes the resulting changes in the values of
other variable.
Goal oriented: it is a process of determining the input values required to achieve a
certain goal.
Risk analysis: risk is important factor which affects the business enterprises. It can be
classified as low, medium and high risk. A DSS is particularly useful in medium risk
and high risk environments.
Model building: DSS allows decision markets to identify the most appropriate model
for solving the problems.
Graphical analysis: this helps managers to quickly digest larger volumes of data and
visualize the impact of various courses of action. They recommend the use of graph
when:
 Seeking a quick summary of data.
 Forecasting activities
 Detecting trends overtime
 Composing points and patterns at different variables.
2. What are the applications can be used in DSS?
Application of a DSS can be classified into following three categories:
Independent problems- the independent problems are “Standalone problems” whose
solutions are independent of other problems. The goal is to find the best solution to
the given problem.
Interrelated problem- in interrelated problems solutions are interrelated by each
other to find the most effective solution to the group of interrelated problem. These
types of problems usually require team effort.
Organisational problems- in Organisational problems all departments within an
organisation are included. Such problem required team effort. TQM is a good
example of an organisational effort because for it to be effective it requires a joint
effort from all departments units in the organisation.

3. What are all the capabilities of executive support system (ESS)?
An effective ESS should have the following capabilities:
Support for defining an overall vision: one of the key roles of senior
executive is to provide a broad vision for the entire organisation.
Support for strategic planning: EIS also support strategic planning. It is
also planning the acquisition of new equipment, analyzing merger
possibilities and making difficult decisions concerning downsizing and
the sale of assets if required by unfavourable economic conditions.
Support for strategic organizing and staffing: top level executive are
concerned with organisational structure .overall direction for staffing
decisions and effective communication with labour unions are also
major decision areas for top level executives.
Support for strategic control: another type of executive decision relates
to strategic control, which involves monitoring and managing the
overall operation of the organisation.
Support for crisis management: even with careful strategic planning a
crisis can occur. Major disasters, include hurricane, tornadoes, floods,
earthquakes, fires and terrorist activities can totally shut down major
parts of organisation.
4.Discuss about advantages and disadvantages of EIS?
Advantages:
Ability to analyze trends
Augmentation of managers leadership capabilities
Enhanced personal thinking and decision making
Contribution to strategic control flexibility
Ease access to existing information
Instruments of change
Better reporting system
Better understanding of enterprise operations.
Disadvantages:

Functions are limited cannot perform complex calculations.
Hard to quantify benefits and to justify implementation of an
EIS.
Executives may encounter information overload.
System may become slow, large, and hard to manage.
Difficult to keep current data.
May lead to less reliable and insecure data.
Small companies may encounter excessive costs for
implementation.
Section-B
1. What do you mean decision support systems (DSS)? What are the characteristics of
decision support systems?
Meaning:
The term DSS refers to a class of systems, which supports the process of making
decisions. The Emphasis is on “support” rather than on automation of decision. DSS allow
the decision maker to retrieve data and test alternative solutions during the process of
problem solving.
Definition:
According to Scott Morton, “DSS as interactive computer based systems, which help
decision makers utilize data and model to solve unstructured problems”.
Examples of DSS:
Group DSS
Computer support Co-operative work
Logistics systems
Financial planning system
Characteristics of decision support systems:
Provide rapid access to information: some DSS provides fast the dashboard of a
car or truck are used to see how the vehicle is running.

Handle large amount of data from different sources: advanced database
management systems and data warehouses have allowed decision makers to search
for information with a DSS even when some data resides in different databases on
different computer systems or network.
Provide report and presentation flexibility: managers can get the information they
want presented in a format that suits their needs. Produce text, tables, line
drawings, pie charts, trend lines, and more.
Support drill down analysis: a manager can get more levels of detail when needed
by drilling down through data.
Perform complex, sophisticated analysis and comparisons using advanced
software packages: marketing research surveys.
2. Discuss about classification of DSS and steps in constructing a DSS?
Classification of DSS:
File drawer systems: these allow immediate access to data item. They are
basically online mechanized versions of manual filing systems.
Data analysis systems: these allow the manipulation of data by means of either
analysis operations tailored to the task or setting or general analysis operations.
Analysis information systems: these provide access to a series of data base and
small models.
Accounting models: these calculate the consequences of planned actions on the
basis of accounting definitions. They typically generate estimates of income,
balance sheets, etc., based on variation in input values to the definitional
formulas.
Representational models: these estimate the consequences of action on the basis
of models that represents some non-definitional characteristics of the systems
such as probabilities of occurrence.
Optimization models: these provide guidelines for action by generating the
optimal solution consistent with a series of constraints.
Suggestion models: these compute a specific suggested decision for a fairly
structured and repetitive decision.

Steps in constructing a DSS:
Choosing the project or problem to be solved.
Selecting hardware and software.
Data acquisition and management.
Model subsystem acquisition and management.
Dialogue subsystem and its management.
Knowledge component.
Packaging.
Testing, evaluation and improvement.
User training.
Documentation and maintenance.
Adaptation.
3. Discuss about advantages and disadvantages of DSS?
Advantages:
Improving personal efficiency: many DSS do not do anything. A person
could not do himself or herself. People prepared budgets for centuries
before spreadsheet software came in to use. DSS help them do it faster and
with less change of error.
Improving problem solving: a DSS can make it possible for a person or a
group to solve problem faster or better, than they could without it.
Facilitating communications: after found that DSS facilitating
interpersonal communication in several ways. In addition technology
developments that have occurred since his or her research have opened up
for DSS to provide this benefit.
Promoting learning or training: using a DSS can also help people learned
more about using computers and about software package that are in the
DSS although this is seldom a specific objective of developing the DSS it
can be valuable by project.
Increasing organisational control: some DSS can also control information
about an individual’s decision to his or her managers.

Disadvantages:
Limited storage capability: due to its small memories and limited storage
capabilities, DSS has definite computational constraints.
Slow: it is slow compared to the speed of large mainframes.
Limited information sharing: most DSSs are designed for individual use
but they can be designed so that several computers can be linked for
limited information sharing.
Difficult: it is difficult to know interdependencies of functions provided by
system.
Require extensive knowledge: there are applications that require
extensive knowledge of specific problem domain or technical knowledge.
Translation problems: users have to deal with several databases and
model each with different data models and resulting translation problems.
Confliction: users may have to work on several decision scenarios at same
time. As a consequence they have to keep track of what they done for each
of them.
4. Discuss about executive information system (EIS) and its characteristics.
Meaning:
ESI are information systems that combine many of the features of MIS and DSS. When
they were first developed their focus was on meeting the strategic information needs of top
management. In some cases and EIS also called executive support system.
Definition:
According to Matthews and Shoe Bridge, “EIS is a computer based information delivery
and communication system designed to support the needs of top executives”.
Characteristics of EIS:
The main characteristics of EIS are as follows:
Drill down capabilities: This capacity of an EIS allows the executives
look for details on any specific information. Each level of detail that is
accessed by the user may involve submenus if the system is menu driven.

Designed with management critical success factors in mind: every
organisation has certain critical factors that are important for achieving the
organisational goals.
Status access, trend analysis, and exception reporting: this feature
allows executives to access the current executives to examine. The timing
and relevance of information is very important.
Personalized analysis: This capability of an EIS allows executives to use
built in functions to analyze problematic situations.

large amounts of data in a quick and efficient manner.
5. Discuss about EIS critical success factors.
A committed and informed executive sponsor: a top level executive,
preferable the CEO should serve as the executive sponser of the EIS by
encouraging its implementation.
An operating sponsor: the executive sponcer will most likely be too busy
to devote much time to implementation.
An appropriate information services staff: information specialist should
be available who understand not only the information technology but also
how the executive will use the system.
Appropriate information technology`: EIS implements should not get
carried away and incorporate unnecessary hardware and software.
Data management: it is not sufficient to simply display the data or
information. the executive should have some idea of how current the data
is.the analysis can be accomplished by drill down by following up with data
managers or both.
A clear link to business objectives: most successful EIS are designed to
solve specific problems or meet needs that can be addressed with
information technology.
Management of organisational resistance: when an executive resists the
EIS efforts should be taken to gain support. A good strategy is to identify a
single problem that the executive faces and then quickly implement an EIS
using prototyping to address that problem.

Management of the spread and evolution of the system: experience has
shown that when upper level management begins receiving information
from the EIS lower level managers want to receive the same output.
