SOME ISSUES OF MIS STRUCTURE

1)Formal Vs Informal information

system.2)Extent of Integration.

3)Extent of User-Machine

Interaction.

Formal Vs Informal information

systemAn organizations complete information

processing system consists of,

1)Public system.2)Private system.

Within the public and private systems we

have both formal and informal informationsystems.

Effect of MIS on relative sizes of information system components


8/15

The public information system of an

organization tends to be larger than theprivate system, but the latter includes a

significant portion of organizational

information flows.By increasing the scope of the formal public

system we can reduce the need for

private, formal system and probablyreduces the need for both public and

private informal systems.


9/15

Increasing the scope of the public formalsystem also has associated costs.

These includes the cost of elicitingrequirements, designing the system,programming, testing, and writing

procedures for operating and using thesystem.

Because of the high cost of developingsystems, tendency has been to only

automate systems that can be justified aspublic systems so that the costs areshared over many users.


10/15

Increasing the scope of the formal public

system we can reduce the time spent by

managers in informal communication, theirproductivity will increase and thus benefit

the organization.


11/15

Extent of Integration

Information systems tend to have a modular

design with integration only whererequired.

Inconsistencies among the subsystems are

reduced by the use of standards and the

common database.


12/15

Data integration is accomplished by the use

of a common database.A common database does not necessarily

eliminate the need for separate files.

Some files are significant only to oneapplication and therefore may be designedfor and maintained by that application.

Data requirements for different levels of

management activity also suggest theneed for more than one database ratherthan complete integration.


13/15

Extent of User-Machine

InteractionThe information system structure does not

specify online user machine interaction: it

indicates only to support for various

operational and management activities.

Online processing of transactions is often

desirable because the transaction is

completed immediately.

Inquires are generally more effective if

immediate response is available.


14/15

The computer system that supports online

transaction processing may not be able to

support interactive models.

However, having an information system

does not imply that a simple computer

system must be used.These approaches encourage managers

and staff specialists to develop their own

support models, rather than depending onthe staff of the information processing

function to provide them.
