With the rapid development of the mobile Internet and the advent of the intelligent era, various industries are gradually transforming to intelligent management, which cannot be separated from software.
Affected by the current epidemic, many companies are struggling on the verge of life and death, and software companies are no exception. There are many software companies, and different software companies have different research and development strengths and focus on development services. How can I select the company that suits me from many software companies? What is the specific development process of software development?
The following will introduce the specific process of software development. Only by understanding the development process can the quality of software products be guaranteed.
1. Feasibility and planning research stage
Feasibility study report: In the stage of feasibility study and planning, it is necessary to determine the development goals and general requirements of the software, conduct feasibility analysis, investment-benefit analysis, develop a development plan, and complete the documents that should be prepared.
Project development plan: The purpose of preparing the project development plan is to record the arrangements for the responsible personnel, development progress, required budget, required software and hardware conditions and other issues in the development process in the form of documents , in order to carry out and check the development work of this project according to this plan.
2. Requirements analysis stage
Software requirements specification: The compilation of software requirements specification is to enable both users and software developers to have a common understanding of the initial requirements of the software, making it the basis of the entire development work. The content includes the regulation of function and the regulation of performance, etc.
Data Requirements Specification: The Data Requirements Specification is prepared to provide technical information on the description of the processed data and data collection requirements throughout the development period.
Preliminary user manual: the compilation of the user manual is to use non-technical language to fully describe the functions and basic usage methods of the software system. Through this manual, users (or potential users) can understand the purpose of the software, and be able to determine how to use it under what circumstances.
3. Design stage
Outline design specification: The outline design specification can also be called the system design specification, and the system mentioned here refers to the program system. The purpose of compilation is to explain the design considerations of the program system, including the basic processing flow of the program system, the organizational structure of the program system, module division, function allocation, and interface design. Operational design, data structure design and error handling design, etc., provide the basis for the detailed design of the program.
Detailed design specification: The detailed design specification can also be called the program design specification. The purpose of compilation is to explain the design considerations of each program (each module or subroutine) in each level of a software system. If a software system is relatively simple and has few levels, this document does not need to be written separately, and the relevant content is incorporated into the outline design manual.
Database design specification: The purpose of compiling the database design specification is to make specific design regulations for all the identification, logical structure and physical structure of the database under design.
The first draft of the test plan: The test mentioned here mainly refers to the assembly test and confirmation test of the entire program system. This document is compiled to provide a test plan for the software, including the content, schedule, design considerations, test data collation methods and evaluation criteria for each test activity.
4. Implementation stage
Module development dossier (begin writing): The module development dossier is gradually compiled during the module development process, and a copy is written every time a module or a group of closely related modules is reviewed, and all the module development dossiers should be brought together . The purpose of writing is to record and summarize the progress and results of low-level development, so as to facilitate the management and review of the entire module development work, and provide very useful technical information for future maintenance. User manual completed
Operation manual: The operation manual is compiled to provide the operator with the specific process and related knowledge of each operation of the software, including the details of the operation method.
5. Testing phase
Module development dossier (must be completed in this stage)
Test analysis report: The test analysis report is written to document the results, findings and analysis of the assembly test and confirmation test.
Project development summary report: The project development summary report is compiled to summarize the experience of the project development work, explain the actual development results obtained and evaluate all aspects of the entire development work.
6. Operation and maintenance phase
The purpose of compiling the monthly development progress report is to report the progress and situation of the project development to relevant management departments in time, so as to discover and deal with problems in the development process in a timely manner. Generally, the monthly development progress report is prepared on a monthly basis by the project team. If the scale of the software system being developed is relatively large, the entire engineering project is divided into several sub-project teams to undertake, and the monthly development progress report will be prepared on a monthly basis with the sub-project team as the unit.
