The Definition of Management Information System

According to Computing Dictionary, the definition in term of noun is a computerized information-processing system designed to support the activities and functions of company management. The standard abbreviation used widely is ‘MIS’.

Meanwhile the definition in term of application is a computer system, usually based on a mainframe or minicomputer, designed to provide management personnel with up-to-date information on an organization’s performance, such as inventory and sales. These systems output information in a form that is useable by managers at all levels of the organization used in strategic planning, tactical, and operational.

And according Wikipedia.com MIS provides information that organizations need to manage themselves efficiently and effectively. Management information systems are typically computer systems used for managing five primary components: hardware, software, data (information for decision making), procedures (design, development and documentation), and people (individuals, groups, or organizations). Management information systems are distinct from other information systems, in that they are used to analyze and facilitate strategic and operational activities.

Academically, the term is commonly used to refer to the study of how individuals, groups, and organizations evaluate, design, implement, manage, and utilize systems to generate information to improve efficiency and effectiveness of decision making, including systems termed decision support systems, expert systems, and executive information systems

Based on my understanding and some reading the simple example of an MIS report is an company annual report that consists of balance sheets and income statement.
