The software development process is a step-by-step process. The entire software development process is divided into four stages that are connected in sequence. Each stage completes all the specified tasks before entering the next stage. From the beginning to the end, a software needs the following: processes:
one. initial demand stage
● User put forward requirements: determine the goal and scope of project development and its feasibility.
● Analyze requirements specification: finalize main functional modules, determine development cycle and quotation.
● Requirement discussion and planning: two-way negotiation, detailed requirement analysis and adjustment of each function that the software needs to realize.
two. contract prototype stage
● Sign the development contract: both parties sign the contract, the customer pays the advance payment and provides manpower, material resources and related assistance.
● Prototype detailed design: The requirement analysis is transformed into the prototype design of the future system that meets the user's expectations.
● Hold a requirement review meeting: After the prototype design is completed, the customer reviews and confirms the specific design, and the supplier begins to write and implement it.
three. Personalized development stage
● Software development and design: Design the entire software system, such as system frame design, database design, etc., develop a robust structure for the system and adjust the design to match the implementation environment.
● Program development and coding: In the development and construction stage, the supplier's programmers develop and integrate all application functions into products according to detailed designs and plans.
● software testing phase: testing to verify the interaction between objects, verify the correct integration of all components in the software, verify that all requirements have been correctly implemented, identify and confirm that defects are raised and dealt with before software deployment.
Four. Delivery maintenance phase
● Product software deployment: The purpose of deployment is to successfully build and distribute the software to end users.
● Formal acceptance of delivery: To determine whether the software, environment, and users can start the operation of the system, the focus of the delivery phase is to ensure that the software is available to end users.
● Post-project maintenance: After the software product is released, modify the application program according to changes in requirements or changes in the hardware environment.
The above are the four stages of the software development process, but it is not necessary to follow this in the software development process. It can be adjusted according to the size and cycle of the project to find the development process that is closest to your company's situation.
