Process of MIS


2/13

1. Plan for MIS development

2. Ascertaining the class of information

3. Determining information requirement

4. Development & implementation of MIS

5. Management of information quality in MIS

Steps for development


3/13

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


4/13

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


5/13

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


6/13


7/13

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


8/13

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.


9/13

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.
