Development, advantages and disadvantages of management information system?

Step 1: Demand investigation and analysis 1. The product manager makes a preliminary understanding of the needs from users, conducts market research, and then lists the main functional modules to be developed by the system in word, and what small functional modules each main functional module has. When some requirements are clear, you can initially define the design in this step. 2. The product manager and the project manager deeply understand and analyze the requirements, and then make detailed functional requirements documents with office tools and prototype design tools according to their own experience and market conditions. This document will clearly list the general main functional modules of the system, which secondary functional modules are included in the main functional modules, and also list the related interfaces and interface functions. What functions should be given priority in the first step of reviewing the overall requirements of the project? What functions are difficult to implement? 3. The product manager reconfirms the demand to the user, signs the contract and enters the research and development.

Step 2: Design 1. Summary design: First, developers need to design the software system, that is, system design. Summary design needs to consider the design of software system, including basic processing flow, organizational structure, module division, function allocation, interface design, operation design, data structure design and error handling design, so as to provide basis for detailed design of software. 2. Detailed design: On the basis of general design, developers need to design the software system in detail. In the detailed design, it is necessary to describe the main algorithms, data structures, hierarchical structure of classes and call relationships involved in the implementation of specific modules, and explain the design considerations of each program (each module or subroutine) at all levels of the software system for coding and testing. You should ensure that the requirements of the software are completely distributed throughout the software. The detailed design should be detailed enough to be coded according to the detailed design report.

Step 3: Coding Development In the software coding stage, according to the design requirements of data structure, algorithm analysis and module realization in the detailed design scheme of the software system, developers start to write specific programs to realize the functions of each module respectively, so as to realize the requirements of the target system in terms of function, performance and interface.

Step 4: Product testing is software testing. The test process is divided into four steps, namely unit test, integration test, confirmation test, system test and release test. Test the written system and prepare for delivery if there is no problem.

Step 5: Preparation for Software Delivery After the software test proves that the software meets the requirements, the software developer should submit the developed target installation program, database data dictionary, user installation manual, user guide, demand report, design report, test report and other products agreed by both parties to the user.

Step 6: Check and accept the delivery of the delivered items, delivered items and final payment. The two sides cooperate happily!

Step 7: After-sales service According to the demand of the demander and the provisions of the contract between the two parties, the developer performs the contract to operate and maintain the product. The above is a rough introduction to the software system development process, which was compiled by Shen Da Bian Xiao according to the industry situation and network information. Shen Da is a global professional platform for the ecological chain of software collaborative industry. Professional product managers in different fields will help you solve the problems of software system development.

The development mode of MIS is 1), which is self-developed and easy to use, but it needs relevant technicians. 2) Entrusted development is convenient, but the cost is high and it is not developed well. 3) Joint development has advantages and disadvantages. 4) Buy several forms of secondary development from ready-made software packages. The cost is low, but because it is not customized, there may be some problems in universality. Generally speaking, it depends on the technical strength, resources and external environment of the enterprise. It is best to recruit a person who knows the system development technology for the statistical post, which not only meets the needs of the post, but also saves the system development cost.
