Research And Application Of Software Process Measurement Model Based On Process Model

Software process measurement is conducive to real-time provide reliable optimization strategy for software development, testing, maintenance, upgrading and re-development.It can reduce the cost of each phase of the software life cycle, find software function invalid module,and improve the efficiency and reliability of the software.It is the key for software process measurement to select the appropriate software metrics, build a reliable and efficient measure model. If you input all the software metrics, then you will cause the curse of dimensionality. On the basis of other measurement model, this paper does the following study about how to extract suitable measure and to establish quantitative measurement model.Firstly, this paper analyzes the existing software process measurement model, and summarizes the advantages and disadvantages of them. On this basis, it puts forward a P-GQIFD (Prepare-Goal Question Indictor Function Data) software process model based on software process model, BP neural network and the traditional measurement method, in order to infiltrate every phase of the software life cycle, to strengthen quantitative measurement capability and to optimiz the process measurement method.Secondary, in order to regulate the experession and description symbol of the metric elements, this paper sets up a unified metric database, according to the P-GQIFD model.The enterprise can expand and improve the metric database in order to meet their own requirements, which simplifies the measurement method and facilitates the accumulation of measurement experience.Finnaly, the P-GQIFD model was tested by college educational management system. It proves that the P-GQIFD can achieve good results by the measurement results.The research shows that, the P-GQIFD model is a kind of intelligent and quantitative measurement method, compared with CMM, CMMI etc.It can extract effective software metrics and intermediate data, and can provide a reliable strategy for software development management.
