What are the steps in the development process of management information system?

The development process of the information system usually includes the following stages: requirements analysis: clarify the purpose, function and requirements of the system, and communicate with customers to ensure the correctness of the requirements. System design: design in detail the functions, data structure, system architecture, etc. of the system.

Basic idea: Introduce the theories and methods of software engineering and system engineering into the research and development of computer systems, and adopt structured and modular top-down analysis and design of the system in accordance with the principle of user-first.

Software system development, information system development, application software system development, etc., are developed by writing code.Software system refers to a computer software system composed of system software, supporting software and application software. It is a part of the computer system composed of software.

Its main process should also be researched and developed according to the idea of software engineering. It can be roughly divided into the following steps: user requirements analysis, overall design of information system, detailed design (code writing), system testing (including black box testing, white box testing, etc.), putting into use, system maintenance and updating.

Development steps of the information system Write the function manual of the screen. The manual describes the business functions of each screen in a standard format and the relationship between the screen and other screens, reflecting the user's views.

The main development methods of information systems include structured methods and prototypes.Law, enterprise system planning method, strategic data planning method, information engineering method and object-oriented method, etc. Structured method Structured method is an information system development method composed of structured system analysis and design.
