8. Management Information System
 MIS provides information to the users
in the form of reports and output from
simulations by mathematical models
 The report and model output can be
provided in a tabular or graphic form

9. Structure of MIS
Difficult concept to understand as there is no universally accepted framework

Basic Structural Concepts
o Formal and informal information systems
o Public and private information systems

11. Formal Information Systems
 There is very clear work-flow system, communication flow-down and the
authority
 The information flows in terms of policies, goals, strategies, rules and
regulations from the top level management to the bottom level of
management
 The information also flows from the bottom level management to the top
level in terms of feedback, results of work done etc.
11

12. There are three categories of information related to the Formal Information Systems:
• Strategic Information - relates to long-range planning policies. This information
is achieved using the Decision Support System
• Managerial Information - helps the middle level management in policy
implementation and control. This information is achieved using the
Management Information System
• Operational Information - is the daily information needed to operate the
business. This information is achieved using the Data Processing System
12

13. Informal Information Systems
 Informal Systems is the systems created by ad hoc, informal work
groups to support information needs that cannot be met by formal
systems
 These are powerful systems that meet unique needs and thrive in
many organizations
 Informal systems do not follow any formal or pre established rules
for collecting, processing, storing, or disseminating data

14. Depending on the accessibility of information
Some files are shared with all and some files are restricted with the
management only
Private information System (Some private information)
• Certain files not available to all in the organisation
• Shared only with limited and trusted persons
• Created and maintained by a manager
• For their own private use
Public information System:- Access to the information available to
everyone
• Utilized by all personnel
14
Private & Public Information Systems

15. Informal public information system
• In addition to the public formal system ,there also exist informal public system in
order to provide benefits to all persons in the organization who really need such
information .strict rules and procedures may not be found in such systems.
Electronic mails, telephone calls, conversation at public places in the organization
etc are examples of public informal information system
Formal private information system
• Besides these formal and informal public information system, there are also
formal and informal private system in an organization. In the case of formal
private system information is under the custody of the individual owner and his
staff.
• For eg, a marketing manager might have been collected information regarding
sales data relating to a purticuler sales district through his sales staff .In addition
to that the secretary to the manager may also collect and maintain information
relating to sales from some private sources .This information is available only to
the marketing manager and anybody else.

16. Private informal information system
• Many individuals may maintain their own private informal information system for
discharging their duties more effectively and efficiently. It is normally found that
certain executives in an organization may collect valuable information from
informal sources to make their decisions more accurate.
• They collect such type of information through their personal contacts with people.
Such information might be very important and useful for decision making in
certain occasions

of different approaches.

19. Synthesis of MIS
• There are various approaches to describe the structure of MIS
• The structure of MIS has been explained in terms of decision making,
management activity, organizational functions and operating elements
• These different approaches of MIS can be combined to get an overall
perspective of MIS structure
• This process of combining these different approaches of MIS is called
Synthesis of Management Information System
• This can be of two ways
• Conceptual Structure
• Physical Structure
