Information Requirement
InformationInformation
Information can be defined as meaningfully
interpreted data.
From a system analyst's point of view,
information is a sequence of symbols that
can be construed to a useful message.
Information SystemInformation System
"Information is a data that has been
processed into a form that is meaningful to
recipient and is of real or perceived value in
the current or the prospective action or
decision of recipient.”
Management Information SystemManagement Information System
A MIS is an information system that
evaluates, analyzes, and processes an
organization's data to produce meaningful
and useful information based on which the
management can take right decisions to
ensure future growth of the organization.
Information/Data Collection TechniquesInformation/Data Collection Techniques
The most popular data collection techniques include:
Surveys: A questionnaires is prepared to collect the data
from the field.
Secondary data sources or archival data: Data is
collected through old records, magazines, company website
etc.
Objective measures or tests: An experimental test is
conducted on the subject and the data is collected.
Interviews: Data is collected by the system analyst by
following a rigid procedure and collecting the answers to a
set of pre-conceived questions through personal interviews.
Classification of InformationClassification of Information
Information can be classified in a number of
ways, two most important ways to classify
information are-
Classification by Characteristic
Classification by Application
Classification by CharacteristicClassification by Characteristic
Based on Anthony's classification of
Management, information used in business
for decision-making is generally
categorized into three types:
Strategic Information
Tactical Information and
Operational Information
Strategic Information:Strategic Information:
Strategic Information: Strategic
information is concerned with long term
policy decisions that defines the objectives
of a business and checks how well these
objectives are met.
For example, acquiring a new plant, a new
product, diversification of business etc,
comes under strategic information.
Tactical InformationTactical Information
Tactical Information: Tactical information
is concerned with the information needed
for exercising control over business
resources, like budgeting, quality control,
service level, inventory level, productivity
level etc.
Operational InformationOperational Information
Operational Information: Operational
information is concerned with
plant/business level information and is used
to ensure proper conduction of specific
operational tasks as planned/intended.
Various operator specific, machine specific
and shift specific jobs for quality control
checks comes under this category.
Classification by ApplicationClassification by Application
In terms of applications, information can be
categorized as:
Planning Information
Control Information
Knowledge Information
Organizational Information
Functional/Operational Information
Database Information
1. Planning Information:1. Planning Information:
These are the information needed for
establishing standard norms and
specifications in an organization. This
information is used in strategic, tactical, and
operation planning of any activity.
Examples: Time standards, Design standards.
2. Control Information:2. Control Information:
This information is needed for establishing
control over all business activities through
feedback mechanism. This information is
used for controlling attainment, nature and
utilization of important processes in a system.
When such information reflects a deviation
from the established standards, the system
should induce a decision or an action leading
to control.
3. Knowledge Information3. Knowledge Information
Knowledge is defined as "information about
information". Knowledge information is
acquired through experience and learning,
and collected from archival data and research
studies.
4. Organizational Information:4. Organizational Information:
Organizational information deals with an
organization's environment, culture in the
light of its objectives.
Karl Weick's Organizational Information Theory
emphasizes that an organization reduces its
uncertainty by collecting, managing and using
these information prudently. This information is
used by everybody in the organization;
Examples : Employee and payroll information.
5. Functional/Operational Information:5. Functional/Operational Information:
This is operation specific information. For
example, daily schedules in a
manufacturing plant that refers to the
detailed assignment of jobs to machines or
machines to operators. In a service oriented
business, it would be the duty roster of
various personnel. This information is
mostly internal to the organization.
6. Database Information6. Database Information
Database information construes large
quantities of information that has multiple
usage and application. Such information is
stored, retrieved and managed to create
databases.
For example, material specification or
supplier information is stored for multiple
users.

Designing of MISDesigning of MIS
Developing MIS is Long term Plans
The plan for development and its implementation is a
basic necessity for MIS.
In MIS the information is recognized as a major
resource like capital, time and capacity.
It is necessary to link its acquisition, storage, use
and disposal as per the business needs for meeting
the business objectives.
So we need MIS flexible enough to deal with the
changing information needs of the organization. It
should be open system. The designing of such an
open system is a complex task.
It can be achieved if MIS is planned, keeping in
view, the plan of the business management of the
organization.
1. System Approach- 1. System Approach-
For Developing MISFor Developing MIS
When the systems approach to problem
solving is applied to the development of
information systems solutions to business
problems, e-business systems and
applications can be developed that meet the
business needs of a company and its
employees and stakeholders.
What is the Systems Approach?What is the Systems Approach?
A problem solving technique that uses a systems
orientation to define problems and opportunities and
develop solutions.
Analyzing a problem and formulating a solution involves
the following interrelated activities:
–Recognize and define a problem or opportunity using systems
thinking
–Develop and evaluate alternative system solutions
–Select the system solution that best meets your requirements
–Design the selected system solution
–Implement and evaluate the success of the designed system
What is Systems Thinking?What is Systems Thinking?
Seeing the forest and the trees in any
situation by:
–Seeing interrelationships among systems
rather than linear cause-and-effect chains
whenever events occur
–Seeing processes of change among systems
rather than discrete snapshots of change,
whenever changes occur

Quality in MIS
Quality in MISQuality in MIS
Information is a corporate resource, as
important as the capital, labor, know-how,
etc. and is being used for decision making.
Its quality, therefore, is required to be very
high.
Low quality information would adversely
affect the organizational performance as it
affects decision making.
The quality of information is the result of -
quality of the input data, processing design,
system design, system procedure which
generate such a data, and the management.
Quality, is not an absolute concept. Its
level is determined with reference to the
context and its use, and the user.
Perfect quality just as perfect
information is non-achievable and has
cost benefit implications.
Quality of information can be measured on
certain parameters.
All these parameters need not have a very
high value in terms of the unit of measure.
Some parameters may have lesser
importance in the total value on account of
their relevance in the information and its
use.
The quality of the parameters is assured if the
following steps are taken:
1. All the input is processed and controlled.
2.All updating and corrections are completed
before the data processing begins.
3.Inputs (transactions, documents, fields and
records) are subjected to validity checks.
Precautions for better Quality:Precautions for better Quality:
The access to the data files is protected and
secured through an authorization scheme.
Intermediate processing checks are introduced.
Due attention is given to the proper file
selection.
Back-up of the data and files are taken to
safeguard corruption or loss of data.
The system audit is conducted from time to
time to ensure that the computer system
specification is not violated.
The system modifications are approved
by following a set procedure which begins
with authorization of a change to its
implementation followed by an audit.
Systems are developed with a standard
specification of design and development.
Computer system processing is controlled
through programme control, process control
and access control.
The principle of the organization and
structuring the organization to the specific
needs of the function is a prime necessity.
In MIS, number of issues come up and they
are not the same in all the organizations.
Hence, the organization structure of the MIS
would differ from one organization to the
other.
Quality in Humanware-
For handling the MIS function and management alternatives
proper - type, the size and the structure of corporate
organization should be there.
The major issues involved are:
Whether the function should be handled as a centralized or
decentralized activity.
The allocation of the hardware and software resources.
The maintenance of the service level at an appropriate level.
Fitting the organization of the MIS in the corporate
organization, its culture and the management philosophy.
The management of the database becomes
the centralized responsibility and its use
becomes the responsibility of users.
The MIS functions in any organization
would vary on account of the issues.
