A Deviation Management System for Handling Software Process Enactment Evolution

摘要

An important problem encountered in Process-centered Software Engineering Environments (PSEE) is that software development processes are subject to permanent evolution during enactment. Without managing evolution, PSEEs are condemned to fail in being adopted in software industry. This article presents an original approach to process enactment evolution, based on formal management of process deviations. Deviations are defined as operations that violate process constraints. Once a deviation is detected, a deviation-tolerance model attached to the preset process is used to decide whether to accept or to reject the deviation.
