The Cmm & Cmmi Based Software Process Improvement

During the development of Software Industry, the"software crisis"is still the sticking point. Management problem has been the most important problem instead of technical problem during the software development.Software process is a set of activities, methods, practice and converse process, which can use to develop and maintenance software and related product. The quality of software development and maintenance process has high influence on product's quality and productivity. The goal of software process technology is to manage the software development process through engineering, standardization and formalization.Software Capability Maturity Model (CMM) and Capability Maturity Model Integration (CMMI) developed by SEI provide a conceptive framework for improving the management and development of software product congruously and effectively. Implementing process control base on this framework gives a successful base for continuous process improvement.This paper has described what is process, the importance and necessary of process management and process improvement, the main contents of Software Capability Maturity Model and Capability Maturity Model Integration。Base on my experiences on process improvement for my company, this paper also described how to implement process improvement, how to migrate from CMM to CMMI.The research and practice has proved that software process improvement is not only raising software productivity, improving software quality, reducing development cost, but also shorting development cycle. Much attention has now being paid to this technique in the field of software engineering and will be the effective methods of making the organization's maturity improve continuously.
