Improvements In Research, Based On The Cmmi Sf Company's Software Development Process Management

In recent decades, as computers are applied in all spheres of social production and life, the software plays an increasingly prominent role. The successful project has given us the great economic benefits, but some problems were exposed in software projects and products. With the further exposure of problems, a so-called"software crisis"arises. Therefore, the"software engineering"concept is proposed to solve the"software crisis". With the guidance of seven principles of software engineering, the project management of software engineering has made progress. However, it is pity that the essential problems have not been solved. Then it is realized that the lack of the project management capacity throughout the software project process is the fundamental problem.Capability Maturity Model Integrated (thereinafter referred to as CMMI) is developed and perfected on the basis of Capability Maturity Model (thereinafter referred to as CMM), which is the important achievement in the software area. CMMI has integrated the comprehensive quality management ideas, providing the standard for the software process improvement of enterprise. CMMI rating appraisal of American Camegic Mellon University Software Engineering Institute (thereinafter referred to as SEI) can be used to introduce the standard for different types of software enterprises, in order to effectively carry out the software work and upgrade the level of software quality.The Paper introduces historical background and major parts of CMMI, stepwise approach and the appraisal method of software process capability maturity. The paper adopts the Paleto and the causal analysis theory to analyses the product quality problem and find out three key factors in the software development of SF Company. In Chapter Four, five CMMI key processes of "demand developing", "demand management", "system design", "design realization", "project monitoring"and"project control" have been discussed related to these three key factors. A set of standard processes of SF company software process betterment based on CMMI is proposed accordingly.Although the model of key process management framework discussed in the paper is pertinent, lots of thoughts in the model are summarized from the practice and even better than the practice. So it is very useful and can be referred during the quality management of small and medium level software companies in China.
