The main activities of the system analysis phase are: preliminary investigation of the system, feasibility study, detailed investigation of the system, and the proposal of the new system logic scheme. Preliminary investigation of the system: The preliminary investigation of the system focuses on the overall objective, overall function and development direction of the system. Feasibility study: The feasibility study is to further clarify the system's objectives, scale, and functions, to investigate and analyze the system development background, necessity, and significance, and to propose a preliminary plan for the development of the system as needed and possible. Detailed investigation of the current system: on the basis of the feasibility study, further comprehensive and in-depth investigation and analysis of the current system, clarify the current system operation status, find its weak links, find out the essence of the problem to be solved, and ensure the new system is more effective . Propose the logic scheme of the new system: Mainly clarify the information needs of users, determine the logic function of the new system, and propose the logic scheme of the new system.
