Study Of CMM-Based Software Projects Process Metrics And Control Optimization

This article proposes a core metrics model orientated to software project management. According to practical reforms on present software process, a process model for software process metrics is presented, which defines the roles, contents, activities and related supporting tools and methods for the implementation of software process metrics. The architecture of a process metrics tool supporting software process control with the characteristics of open and adaptability is designed.This article describes and analyzes the tracking and controlling strategies based on the metrics software process; After considering the characteristics of software process projects and CMM, process control theory, It also describes the software process controlling process, produces the tracking and controlling strategies, proposes a software project process controlling optimization model, and designs a optimized algorithm of a dynamic program. When the actual process deviates from the planned tracks, superintendent can use this method to carry on the optimization for available plans and choose the best controlling strategies rapidly.The above-mentioned method after being used in a large-scale software enterprise indicated that process controlling optimization proposed in this article can remarkably promote the superintendent's controlling ability of the software project process, promote reasonable mixing of resources and improve the success rates of software as well. More than a year later, the statistical data demonstrated that this company's project progress controlling ability improved averagely over 30%. The project cost increased in the first 6 months, but it declined a great deal according to the whole year's statistics.
