State the factors to be considered for designing an effective Managing Information System (MIS) Definition of MIS
An organized approach to the study of the information needs of an organization's management at every level in making operational, tactical, and strategic decisions. Its objective is to design and implement procedures, processes,and routines that provide suitably detailed reports in an accurate, consistent, and timely manner. MIS is a general term for the computer systems in an enterprise that provide information about its business operations. It's also used to refer to the people who manage these systems. in a large corporation, "MIS" refers to a central or centrally-coordinated system of computer expertise and management, often including mainframe systems but also including by extension the corporation's entire network of computer resources.
Managing Information System
Management Information Systems (MIS) is the study of people, technology, organizations and the relationships among them. MIS professionals help firms realize maximum benefit from investment in personnel, equipment, and business processes. MIS is a people-oriented field with an emphasis on service through technology Businesses use information systems at all levels of operation to collect, process and store data. Management aggregates and disseminates this data in the form of information needed to carry out the daily operations of business. MIS professionals create information systems for data management (i.e., storing, searching and analyzing data). OBJECTIVES OF MIS:-
An effective MIS has the following objectives
1. Facilitate the decision - making process by furnishing information in the proper timeframe. This helps the decision - maker to select the best course of action. 2. Provide requisite information at each level of management to carry out their functions. 3. Help in highlighting the critical factors to the closely monitored for successful functioning of the organization. 4. Support decision-making in both structured and unstructured problem environments. 5. Provide a system of people, computers, procedures, interactive query facilities, documents for collecting, and sorting, retrieving and transmitting information to the users.
The business application system demands designing of systems suitable to the application in project. The major steps involved in the design are the following: Input Design -
Input design is defined as the input requirement specification as per a format required. Input design begins long before the data arrives at the device. The analyst will have to design source documents, input screens and methods and procedures for getting the data into the computer. Output Design
– The design of the output is based on the requirement of the user – manager, customer etc. The output formats have to very friendly to the user. Therefore the designer has tonsure the appropriateness of the output format. Development
– When the design and its methodology are approved, the system is developed using appropriate business models. The development has to be in accordance to a given standard. The norms have to be strictly adhered to.
Exhaustive and thorough testing must be conducted to ascertain whether the system produces the right results. Testing is time consuming: Test data must be carefully prepared, results reviewed and corrections made in the system. In some instances, parts of the system may have to be redesigned. The purpose of such testing is to guarantee that programs are error free, but this goal is realistically impossible. It tries to determine if discrete modules will function together as planned and whether discrepancies exist between the way the system actually works and the way it was conceived. Acceptance testing provides the final certification that the system is ready to be used in a production setting. Systems tests are evaluated by users and reviewed by management.
