Measuring and Managing In-process Software Quality

Abstract: In this paper we described the effort/outcome model for in-process metrics and quality management. The model goes beyond the traditional way of interpreting metrics and assessing quality when a software development project is underway. We illustrated the use of the model for the testing phase as well as for the front end of the development process with regard to design and code inspections. Improvement paths were discussed and possible effort and outcome indicators that can be used along the phases of software development life cycle were provided. The effort/outcome model and the metrics thus established, used, and interpreted, are clearly an effective way for quality management.
