Applying CMMI to Implement the Expert System of Software Project Management

[[abstract]]In recent years, due to the function structure complexity and the scale of software systems are getting more complicated, software development is not only required to fulfill the software function requirements, but also the quality requirements to reduce the costs of software development life cycle. Under the fast changing software market, to keep strong competitiveness, agile decision-making and good software development techniques are very important. Also, the risk of software development will reduce. Therefore, complete software development processes and auxiliary tools are apparently important. Capability Maturity Model Integration (CMMI) can help software development organization to improve the software project development. Moreover, it can explore the standard software engineering model to assure software quality and shorten the software project development life cycle. In this research, the features of CMMI are applied to the inference mechanism of the inference engine of an expert system using the Process Areas, Goals, and Practices of CMMI. The inference engine uses the facts of the database and the rules of the knowledge base to perform the diagnosis and reasoning. Thus the organization can control the problems of software project management through this mechanism. Furthermore, the solutions obtained from the expert system are applied to improve the problems of the software development project. Eventually, it can establish better project development processes to increase success rate of the project development in an organization
