Research and practice of ministry-level software process improvement based on SW − CMM model

With the continuous innovation of computer software technology, the e-government and other related information work of government departments has received increasing attention. Ministry-level information software projects are characterized by large scale, wide range of users, complex business logic, long project cycle, and large amount of post-operation and maintenance. In order to guarantee the quality of software projects, improve work efficiency, strengthen software process management capability, and effectively deal with software project risks, the article takes SW-CMM model as the basic framework, starts from three management models: project management process, engineering management process, and support activity process, and splits them into 12 sub-process domains according to the actual needs, and elaborates and analyzes the software process improvement of ministry-level information projects The main points of software process improvement for ministry-level information technology projects are elaborated and analyzed. Combining with the software engineering process improvement practices of actual software organizations, the corresponding implementation strategies are elaborated in six aspects, including controlling key links, covering the whole life cycle, promoting development standards and specifications, strengthening requirements management, enhancing project asset management and strengthening risk management, which provide an optimal solution for the process improvement of ministry-level software projects.
