Introduction
The Management Information System (MIS)
is a concept of the last decade or two. It has been understood and described in
a number ways. It is also known as the Information System, the Information and
Decision System, the Computer based information System.
BASIC ELEMENTS OF MANAGEMENT INFORMATION SYSTEM
The three components in MIS gives a more
complete and focused definition, where System suggests integration and holistic
view, Information stands for processed data and Management is the ultimate
user, the decision makers.
Management information system can thus
be analyzed as:
Management:
Management covers the planning, control,
and administration of the operations of a concern. The top management handles
planning; the middle management concentrates on controlling; and the lower
management is concerned with actual administration.
Information:
Information, in MIS, means the processed
data that helps the management in planning, controlling and operations. Data
means all the facts arising out of the operations of the concern. Data is
processed i.e. recorded, summarized, compared and finally presented to the
management in the form of MIS report.
System:
Data is processed into information with
the help of a system. A system is made up of inputs, processing, output and
feedback or control. Thus MIS means a system for processing data in order to
give proper information to the management for performing its functions.
Management
Management is a vital aspect of the
economic life of man, which is an organised group activity. It is considered as
the indispensable institution in the modern social organization marked by
scientific thought and technological innovations. One or the other form of
management is essential wherever human efforts are to be undertaken
collectively to satisfy wants through some productive activity, occupation or
profession. It is management that regulates man's productive activities through
coordinated use of material resources. Without the leadership provided by
management, the resources of production remain resources and never become
production.
Management is the integrating force in
all organized activity. They also have to organize and utilize their resources
in such a way as to optimize the results. Not only in business enterprises
where costs and revenues can be ascertained accurately and objectively but also
in service organizations such as government, hospitals, schools, clubs, etc.,
scarce resources including men, machines, materials and money have to be
integrated in a productive relationship, and utilized efficiently towards the
achievement of their goals.
Thus, management is not unique to business
organizations but common to all kinds of social organizations. Management has
achieved an enviable importance in recent times. It is the most vital forces in
the successful performance of all kinds of organized social activities.
Composition
of MIS
MIS is a system or process that consists
of people, machines, procedures, data methods and database as the elements of
the system. Different components of MIS are discussed follows:
Physical
component
1) Hardware:
The hardware components of MIS are all
the input and output devices which helps the feeling and displaying the
information as per requirement. Different input devices are keyboard, scanners
and mouse etc. The output devices are monitor, printer, network devices etc.
Hardware devices are the physical parts of MIS. These can help in maintaining
the data of business.
2) Software:
Software are the programs and
applications which convert machine into readable language. Different software
generally used for processing the information of an organization are ERP and
CRP, ERP is software package that combines all data and processes of an
organization. In order to achieve the integration, it uses multiple components
of computer software as well as hardware. Advantage of ERP system is that it
uses a single, unified database to store data for various systems. Under ERP
system all functions of an organization can be controlled. On the other hand,
ORM is a software package which includes the capabilities, methodologies and
technologies to support an organization in managing the relationship with
customers. ORM can enable the organization to manage their customers through
the introduction of reliable systems, processes and procedures.
3) Procedures:
Procedure implies a set of sales and
guideline, which are established by an organization for the use of a computer
based information system, Procedure depends on the nature and purpose of the
organization. So procedures are different for different organizations. Moreover,
it may vary from one department to another department according to requirement.
As for example, production department requires information on raw materials,
quality of goods etc. But the sales department requires information on quality
of goods to be sold, the expenditure of sale etc. So, different departments
have to set their procedures in different ways so that the MIS can help in
retrieving the information as per requirement of a particular department.
4) Personnel:
Different personnel of MIS are computer
experts, managers, users of computer based information system. Majority of the
personnel use the computer based information for preparing plans and
programmes, rules and regulations, and for taking different decisions.
Information
System
1) Collection of Data:
The designing of MIS is based on the
collection of data. Generally, data are not collected independently for special
purposes, but they are collected for multiple uses; such as, data of inventory
can be used by managers in production, accounting and purchase department.
After collection of data, assembly is immensely important. Data should be
assembled according to needs and purposes of the management. There are mainly
two sources of data and information: Internal source and external source. The
company should use both these sources.
2) Processing:
In the second step, data should be
processed in a systematic manner. Processing of data implies editing of data,
their classification and summation. By the editing of data, correction and modification
can be done and classification should be done according to the need of
organization. Summation is the process of grouping the data on the basis of
similar nature as well as purpose.
3) Storage and Retrieval:
In this step of
MIS different activities such as indexing, coding, filing of data and
information are done. As a result of this step, the managers and directors of
the company can easily use and operate the data and information as per their
requirement.
4) Evaluation:
It is an important step, where accuracy
and relevance of data can be determined. Determination of relevance of data is
immensely important for taking effective decision at each level.
5) Dissemination :
By this step relevant information is
supplied in the proper form at the right time. Information should be supplied
according to the requirement of the top management. So, it may be different for
different companies and also may be different at different times of the same
company.
Steps of MIS can be changed by different
companies according to their nature of activities. So, the steps should be
determined as to provide the information systematically for taking effective
managerial decisions. According to Stoller and Horn the designing of MIS
consists of following steps
Ø
Defining the
operating and planning decisions that are required to manage the organizations.
Ø
Exploring the
types of policies available for making each decision.
Ø
Determining the
data requirement implied by each decision policy.
Ø
Developing
preferred processing techniques for desired data set.
Decision support system
The interrelationship of the sub systems
within an organization is fundamental to the systems approach. The different
components of the organization have to operate in a coordinated manner to
attain common organizational goals. This results in synergic effects. The term
synergy means that when different sub systems work together they tend to be
more efficient than if they work in isolation). Thus, the output of a system
with well integrated sub systems would be much more than the sum of the outputs
of the independent sub systems working in isolation.
The systems approach provides a total
view of the organization. It enables analysis of an organization in a
scientific manner, so that operating management systems can be developed and an
appropriate MIS.
By providing the required information,
an MIS can help interrelate, coordinate and integrate different sub systems
within an organization, thus facilitating and increasing coordinated working of
the sub systems, with consequent synergism. The interaction between different
components of the organization depends upon integration, communication and
decision making. Together they create a linking process in the organization.
Integration ensures that different sub
systems work towards the common goal. Coordination and integration are useful
controlling mechanisms which ensure smooth functioning in the organization,
particularly as organizations become large and increasingly complex. As
organizations face environmental complexity, diversity and change, they need
more and more internal differentiation, and specialization becomes complex and
diverse. The need for integration also increases as structural dimensions
increase.
Communication integrates different sub
systems (specialized units) at different levels in an organization. It is thus
a basic element of the organizational structure necessary for achieving the
organization's goals.
Organizational structure and MIS
MIS has been described as a pyramidal
structure, with four levels of information resources. The levels of information
would depend upon the organizational structure. The top level supports
strategic planning and policy making at the highest level of management. The
second level of information resources aid tactical planning and decision making
for management control. The third level supports day to day operations and
control. The bottom level consists of information for transaction processing.
It then follows that since decision making is specific to hierarchical levels
in an organization, the information requirements at each level vary
accordingly.
Thus, MIS as a support system draws
upon:
Ø
concepts of
organization;
Ø
Organizational theories,
principles, structure.
Ø
Motivation and leadership
behavior.
Approaches to MIS:
There are two
basic approaches for development of MIS:
a) System development life cycle:
The system
development life cycle have following steps of development:
i) Systems Planning
ii) Systems Analysis
iii) Systems Design
iv) Systems Implementation
v) Systems Operation and Support (System Maintenance)
b) Prototyping:
Prototyping is the process of creating
an incomplete model of the future full featured system, which can be used to
let the users have a first idea of the completed program or allow the clients
to evaluate the program.
Advantages:
i) The
designer and implementer can obtain feedback from the users early in the
project development.
ii) The client
and the contractor can compare that the developing system matches with the
system specification, according to which the system is built.
iii) It also
gives the engineer some idea about the accuracy of initial project estimates
and whether the deadlines can be successfully met.
The process of prototyping involves the following
steps :
i) Identify basic requirements.
ii) Develop initial prototype.
iii) Review: The customers, including end users,
examine the prototype and provide feedback for additions or changes.
iv) Revise and Enhance the Prototype: Using the
feedback both the specifications and the prototype can be improved.
Contemporary approaches to MIS
When an information system is being
developed, much importance should be given to the structure of the
organization, culture of the organization, etc. But along with these, especial
attention should also be given to the technical side of MIS. The various
contemporary approaches to MIS development can be summarized as
1. The Technical Approach
a) Based on the mathematical and the normative models.
b) Physical technology forms the back bone of such an
approach.
c) Such an approach mainly finds much needed
contributions from the disciplines like computer science, management science,
operations research etc.
2. The Behavioral Approach
a) Based on the impact of the behavior and also on the
response of the people in the organization.
b) Motivational Feasibility forms a very important and
demanding part of such an approach towards MIS development.
3. The Socio Technical Approach
a) In the beginning, this approach was finding it hard
to survive – but now it is being accepted worldwide and is also being
implemented at a very large scale.
b) Involves key involvement of both of the above
explained approaches.
c) Improves the performance of the information system
as a whole.
