Contents of MIS Plan
1. Decide goals & objectives for development of MIS.
E.g. to provide online information on stock, markets &
accounts balances.
2. Decide the strategy for plan achievement.
e.g. Development strategy, resource utilization strategy
etc.
3. Architecture of MIS
4. System Development Schedule
5. Hardware & software Plan

Following classes of information should be confirmed and
information is gathered:
1. Organizational: Number of employees, product,
services, turnover2. Functional: purchases, sales, production, stocks
3. Decision Support: Status information on a particular
aspect, e.g. profitability standard, inventory. Used by
middle management & operational management
4. Operational: Information on production, sales,
monitoring of execution schedules. Used by operational
management & supervisors.
Ascertaining the class ofinformation

Four methods of determining information
requirements:
1. Asking or interviewing
2. Determining from existing system
3. Analyzing critical success factors
4. Experimentation & modelling
Determining informationrequirement

The knowledge of system can be available on
handbooks, research studies which can determine the
information requirement.
Existing system can be studied by observation,
referring all documents.
For observation, the things to be observed should be
decided prior and planned.
Determing from existing system

Analysing critical success factors
Critical factors are studied separately.
Those are identified first, criticality is determined by
designers.
Information of effects of critical factors are studied
and if required contingency planning is done.

Experimentation & modelling
If there is uncertainty in some information, it can be
fixed by experimenting or modelling.
For experimentation proper method is designed. After
implementation of this method, the information will
be gathered which can be considered certain & fixed.
Sometimes the models are designed for experiments.
Due to this technique, the users get benefit oflearning and experience and facts may change or get
replaced completely.

Development & Implemenation ofMIS
Two approaches can be used here:
1. Prototype Approach:
Prototyping is the method of assuming some
information needs, developing methodology and
allowing the user to use it.
After use the users feedback is important to modify the
methodology.
This process when it identifies the loopholes in
methodology it also takes the feel of actual
implementation. Hence, user feedback is more

2. Life Cycle Approach:
Some systems of MIS have life cycle i.e. system is
initialized and ended.
Such systems are very much structured and rule-
based.
They have clearance about inputs their sources and
outputs. Examples of such systems are pay roll, financial
accounting, order processing etc.
