Sub System of MIS

What are the different Sub-System of MIS?
Ans.: The system approach applies equally to management information system as well. The management information system receives input form various internal and external sources. These inputs are processes through the MIS to produce the desired output, which may be in turn used for different managerial task within the organization. MIS has several subsystems which are interdependent, interrelated and interacting.
The Sub-Systems within the MIS are :
Computer System : The computer system as a subsystem of MIS includes the Hardware, the operating system and the software.
Management : The management system as a subsystem of MIS includes the managerial task relating to the effective functioning. It includes planning, control and co-ordination, human resource development etc.
System Engineering : The system engineering subsystem of MIS includes system design and development as well as system maintenance. The synergistic combination of hardware and system engineering is evolved into software engineering. Software engineering as defined by Fritz Baucer, as the establishment and use of engineering principals in order to obtain economically feasible software that is reliable and works efficiently on real machines.
Application : The application subsystem of MIS includes various application system, which are developed and implemented to the desire outputs.
This process of integration of business system with management information system involves three key elements. They are :
a) Technology
b) People
c) Business
Technology : Technology provides the bridge between the business systems, their information needs on one side, the means of providing these information needs on the other. Technology provides the tools and techniques that help to generate the information that are required for the business system. Selection of the appropriate technology has got bearing on effectiveness of the bridge.
People : People generate the required information and apply the same for business planning, control and decision making. The attitude and aspiration of the people involved in generating and utilizing the information has a bearing on effective use of integrated system.
Business : The business function and the environment in which the business organization have an impact on the entire integration exercise.
