| Software producing is a very complex process. Since several years ago that computer appeared first, searching for new software method and technology to improve software production has always been a focus in software engineering research area. During nondisciplined and disordered software processes, time plan and budget are badly followed. In 1987, according to the problems arise in software production, the SEI of American Carnegie Mellon University put forward a software Capability Maturity Model(CMM).It is mainly used to evaluate and improve the software developing process and software developing capability. Then, because of the success of CMM, many similar models appeared. In order to integrate these model, SEI put forward another model—CMMI(Capability Maturity Model Integration).In our country, software industry is still a new but potential industry. Software companies are facing not only the troubles coming from the company, but also the competing pressure in Chinese even international markets. So it's very important and urgent for our software companies the find a proper way to improve the software production. This paper is mainly to study a proper way for Chinese software companies to improve software process, and advise something needed to pay attention to when applying CMMI.Chapter one is the summarization. We introduce software Characters, problems found in software production. And then, we elaborate how CMM and CMMI begin to come to being.Chapter two begins with the basic notion, including the system framework of CMMI and the difference between CMM and CMMI.Chapter three is mainly about the process area—measurement and analysisChapter four shows the design and the realization of a measurement system module.The last chapter summarizes my work and plans in the future. |
