10. MIS Basic Structural Concepts Formal and informal information systems Public and private information systems 10

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 13

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. 15

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 16

17. MIS structure can be can be described by variety of different approaches. Based on Physical Components IS processing Functions Levels of management activities Organisational functions 17 Public & Private Formal & Informal

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
