The Research And The Application Of Testing Management And Improvement Model On CMM

Nowadays, software testing which is critical in quality management is thought highly. But in China, many software companys misunderstand the testing process, and there is no enough testing model for application. So they need a good testing model for managing their testing process and for improving their software quality.A good testing is not overall, but lowering the software risk. So risk analysis is necessary in testing design. In TQM(Total Quality Management) theory, testing is no more after the coding process, instead, Testing should be parallel with the software development. And it can find defects as early as possible, which can shorten the development cycle and lower the risk to increase the software quality.To get a effective testing, software companys need testing process management methods like CMM to restrain the activities, but CMM and CMMI neither have the KPA specially for testing. In order to promote testing process, the papers analyse the testing mangement and improvement model on CMM both in theory and practical.The papers describe the defects of v model and testing management tools. To make up CMM's defects, it design a testing management and improvemet model on CMM, it not only tell company what to do when testing, but also how to do system testing. So after research on many latest testing technologies, the papers analyse the methods for requirement testing, risk analysis, defects statistics and testing process improvement. This testing model standardizes the testing management and improve the testing efficiency. Especially for the testing in different builds, the testware can be reused, and software can be compared to different builds.Otherwise, the papers give a example of a real testing project, it introduces every step and correlated documents in testing process. The requirement testing and system testing aiming at the highest risk can guarantee the software quality. Defects which can indicate the problems of developing process are helpful for process improvement.The TPI model can integrate with the CMM model, so company can improve the testing process maturity in the CMM process improvement.
