Research And Application For Software Process Mprovement Measurement Model Based On CMMI

Currently, the21st century, with the rapid development of the computer software industry, software process improvement has become a hot international software engineering research. In software projects, always encounter such as cost overruns, schedule delay, the quality does not meet the requirements of other issues, which need to have a global control of the software process, software process measurement is an effective software process improvement methods.Software Process Improvement (SPI, Software Process Improvement) to help software change or improve their software processes for planning, formulation and implementation of the measures is to establish enterprises for their own standardized, automated processes only way, however, for software process theory and there is still a gap between research and application of technology, software process improvement process is tailored to the theoretical and model as the basis, fully integrated software characteristics and status of the organization itself, cutting out the software for their own development process characteristics improved model for their own development in order to find a good efficiency improvements received fruit. And to understand software features and status of the organization itself, the software process metrics is the basic means. Software process measurement is a means to measure the deviation between the actual performance of the organization and acceptable performance, but also an important way to improve the organization the opportunity to get. Currently, the measurement and analysis has become an independent process CMMI process areas, more and more importance in enterprises.CMMI is a successful, widely-used software process improvement model for enterprises to implement software measurement, process control and improvement, from disorder to provide a standardized process. But the CMMI model SMEs in the implementation process, there are still many problems. For example, CMMI model describes the objectives and requirements of software metrics and analysis, but did not specify how to create and implement these measurement process; And, in the beginning stages of software process improvement, process control software to implement greater cost metrics.CMMI model for the current situation in the actual application process and the problems of SMEs in China, feature article for the implementation of software process improvement for guiding the direction to software process measurement as a means to measure and analyze from the perspective of research and analysis on the line CMMI model, combined with GQM measurement model and the actual needs of SMEs, SME propose a suitable measure process improvement model GQIM, and the model is a formal description.To validate the model of scientific, measure the results of objectivity in data collection and analysis phase, by introducing SPC statistical process control methods to verify the results of the analysis, to establish a set of organizational process performance baseline model for enterprise decision-makers in the implementation of software process improvement to provide effective support and guidance to lower defect rates, control risk and improve product quality to meet the companies hope to lower the cost of improvements to achieve good results in demand, especially for SMEs more practical significance.
