CMMI In Samll And Medium-sized Software Company

In the IT industry, there are many models for software process managing andimproving, and the most influential is the Capability Maturity proposed ModelIntegration-CMMI (Capability Maturity Model Integration), which put forward byCarnegie Mellon University Software Engineering Institute (SEI). It provids a range oftarget, witch the project manager can establish a standard system of processmanagement based on. And solve the problems of software quality unstable, progressuncontrollable.The topics to CMMI implementation process in small and medium enterprises asthe research object, in view of the present situation of small and medium enterprises inChina, such like small-scale, lack of human resources, focused on technology andcontempt management. Carried out in-depth analysis on the management architecture ofCMMI, combines the advantages of management, software engineering and technicalabout CMMI. Made the key practices of CMMI combines process of softwaredevelopment. CMMI-2level in the company commissioning projects and review project,for example, Start from analysising the status of the company’s software management,then find the suitable maturity model from CMMI. Expound the methods, process andeffect about CMMI implementation of small and medium-sized software projects. Baseon the ongoing operation project and cycle of software development.As test and PPQA role in this implementation, the author made a detaileddescription of the process of testing related works. And made conclusions from theperspective of testing. From the effect of implementation, it seems small and mediumsoftware enterprises to implement CMMI process can effectively improve the softwareprocess capability and improve software quality.This thesis describes the whole implementation process which is based on theactual software development project–Document Security System version2. Thesystem is mainly for all kinds of enterprise document provides automatic encryptionfunction, through powerful user group management, enabling departments toindividual-level access control. And provide online use, offline use, USB Key use means of access management.
