In systems engineering, software engineering, and computer science, a function model or functional model is a structured representation of the functions ( activities, actions, processes, operations) within the modeled system or subject area. That is the simple definition of MIS that generally sums up what a Management Information System is, and what Definition of Management Information Systems: 1. Unformatted text preview: DEFINITION OF CROSS FUNCTIONAL INFORMATION SYSTEM A cross-functional information system is the third era of information systems, after calculations systems and functional systems.Cross-functional systems were designed to integrate the activities of the entire business process, and are called so because they 'cross' departmental boundaries. Functional area in SAP, is an organizational unit that classifies the operating expenses of company according to functions administration, sales and distribution, marketing, production and research & development. A functional system consists of a set of functions and a set of operations that are applied to the functions. It can be a calculation, data manipulation, business process, user interaction, or any other specific functionality which defines what function a system is likely to perform. A management information system (MIS) is a computer system consisting of hardware and software that serves as the backbone of an organizations operations. Who is the antagonist in love in the cornhusks? A function is nothing but inputs to the software system, its behavior, and outputs. Invented in time to process the 1890 U.S. census, Holleriths machine represented a major step in automation, as well as an inspiration to develop computerized information systems.
