Management information system analysis, referred to as System Analysis, is also known as requirements analysis or logical design. System analysis must investigate, study, decompose, and analyze the internal and external situation of the existing system from a system standpoint, in order to provide a scientific foundation for determining the objectives of the new system and the program of the new system, to lay a solid foundation for future system design and system implementation, and to provide a basis for system acceptance.
System analysis is guided by system planning, in-depth and detailed investigation and study of the existing system to determine the logical model of the new system, and logically define the functions of the new system, but it does not involve physical implementation of the new system, that is, to solve the system "what" but not "how to do it." That is, to address the issue of "what" the system does rather than "how" it does it. The primary goal of the system analysis phase is to comprehend the user requirements and create the logical model of the new system.
The system analysis phase's main contents are a detailed investigation of the existing system, requirements analysis, and the establishment of a new system logic model.
Sending questionnaires, holding survey meetings, interviewing, and participating in business practices are the main methods of system survey.
Business process is the process of handling each business activity in the existing system. It is possible to understand the specific processing of a business, discover possible errors or omissions in the business process of the original system, modify and delete unreasonable parts of the original system, and optimize the business process of the new system through detailed investigation of the business activities of each link in the system, mastering the content, role, and information input, output, storage, processing, and handling of each business.
A business flow diagram (TFD) is a diagram that describes the business relationships, sequence of operations, and information flow between departments, departments and personnel, and personnel in an organization.
Because data is the primary carrier of information and the primary object of MIS processing, collecting and organizing data is the foundation of data flow analysis.
Official documents within each department, such as various documents, cards, reports, business processing flow charts and work procedures, and so on; external data from each department, such as documents from superiors, bills from outside units, and other related information, are among the data collected. The large number of original documents collected, statistical tables, summary statements, questionnaires, and other information gathered by investigators based on organizational structure and business processes typically only partially reflect the data needs of a specific business and data management in a single department.
