Colloquium - Cangussu

A State Variable Approach for Feedback Software Process Control
Department of Computer Sciences, Purdue University

A novel approach to model the system test phase of the software life cycle is presented. This approach is based on concepts and techniques from control theory and is useful in computing the effort required to reduce the number of errors and the schedule slippage under a changing process environment. Results from these computations are used, and possibly revised, at specific checkpoints in a feedback-control structure to meet the schedule and quality objectives. The use of a formal approach allows for automatic calibration of the model by means of System Identification techniques. A sensitivity analysis based on tensor product is conducted to analyze the model behavior for variations in the parameters. Two case studies were conducted to study the behavior of the proposed model. One study uses data from a commercial project. The outcome from these two case studies combined with the results of the sensitivity analysis suggest that the proposed model might well be the first significant milestone along the road to a formal and practical theory of software process control.
