1. STRUCTURE OF MIS MIS UNIT III

2. DIFFERENT APPROACHES Structure of MIS is a difficult concept to understand because there is no standard or universally accepted is no standard or universally accepted framework for describing management information framework for describing management information system . For example , A car may be perceived in a system . For example , A car may be perceived in a number of different way; by describe the physical number of different way; by describe the physical characteristics , i.e. its shapes, colour , seating capacity , characteristics , i.e. its shapes, colour , seating capacity , door etc. MIS structure be described by following a door etc. MIS structure be described by a variety of different approaches.

3. DIFFERENT APPROACHES Decision support Information system processing functions Physical components Outputs for users Organizational functions Levels of management activities

4. STRUCTURE OF MIS

5. BASED ON PHYSICAL COMPONENTS HARDWARE: CPU, Monitor, Keyboard etc . SOFTWARE: System, operating system etc. DATABASE: Data stored in files PROCEDURE: Manuals etc. OPERATING PERSONAL: Computer operators, programmers, system analysts, system managers ect . INPUT & OUTPUT: Printouts, reports etc.

6. BASED ON PROCESSING FUNCTIONS To process Transactions To maintain Master files To produce Reports To process Enquiries To process Interactive Support Applications

7. BASED ON OUTPUTS FOR USERS Transaction documents or screens Preplanned reports Preplanned inquiries responses Adhoc reports & inquiry responses User-machine dialog results

8. BASED ON DECISION MACKING Structured/programmed Decisions Unstructured/Non-programmable Decisions Semi-structured Decisions

9. ROLL OF MIS IN AN ORGANIZATION The roll of MIS in an organization can be compared to the role of heart in the body. Management information system (MIS) is one of the major computer based information systems. Its purpose is to meet the general information need of all the managers in the firm or in some organizational subunit of the firm. There are many definitions for MIS, but one of the most appropriate definitions describes management information system (MIS) as " an organizational method of providing past, present and projected information related to internal operations and external intelligence . It supports the planning, control and operation functions of an organization by furnishing uniform information in the proper time frame to assist the decision makers" The information in MIS describes the firm or one of its major systems in terms of what has happened in the past, what is happening now and what is likely to happen in the future. The information is made is available in form of periodic reports, special reports and output of mathematical simulations. All managers use the information output as they make decisions to solve the firm’s problems

10. MIS - Implémentation, Evaluation, and Maintenance To increase the operating efficiency of the system, employees should also be trained in terms of operating the MIS in their specific functions. The implementation process is easy to carry out if the employees accept the changes in the organization. The process starts with planning for implementation where relationships among various tasks have to be identified and established , schedules for completing all the tasks should be prepared, cost estimates for various tasks have to be drawn up, and a reporting and control system has to be established.

11. MIS - Implémentation, Evaluation, and Maintenance Once the planning is done, the implementation process can be executed smoothly. The steps in the process include: organizing for implementation, developing procedures for implementation, training the users, acquiring hardware and software, developing forms for data collection, developing files for storage of data, testing the system, cutover, and documenting the system. The implementation process should be followed by evaluation of the implementation. The MIS can be evaluated for the efficiency with which the allocated resources are utilized in the development / implementation and the effectiveness of its usage after the implementation.

12. MIS - Implémentation, Evaluation, and Maintenance The top management's commitment toward the MIS implementation is the strongest defense that can be built up against all these challenges. The top management's support helps the organization to win over the different challenges and problems that can surface during the implementation.

13. Steps Involved in Implementing MIS Plan the implementation. Assign Implementation tasks Planning the implementations tasks. Establish Relationship among tasks. Establish a schedule. Cost schedule to task and time. Acquiring & Layering out Facilities and Offices. Organizing the Personnel for Implementation. Developing procedure for installation and testing. Developing the training program for operating personnel.

14. Steps Involved in Implementing MIS continu… Completing the system’s software. Acquiring required hardware. Generating files. Designing forms. Testing the entire system. Completing cutover to the new system. Documenting the system. Evaluating the system. Providing system maintenance.

15. Plan the implementation The initial installation. The test of the system as a whole. The evaluation, maintenance & control of the system.

16. Establish Relationship among tasks In a project many task are interrelated. Many tasks can be carried out concurrently. Some tasks are sequential. Good planning is to perform concurrent tasks simultaneously.

17. Establish a schedule Estimate the time required to implement MIS. Specify the starting date and end date for all the tasks.

18. Cost schedule to task and time Cost estimation for completing each task required to complete the plan. Financial personnel prepare report format to show cost and technical progress relationship as well as cost and time.
