Process evolution support in concurrent software process language environment

This article describes the process evolution support in concurrent software process language (CSPL) environment. Process evolution refers to dynamically changing process programs during process enactment. It is required in process-centered software engineering environment (PSEE) because: (1) parts of a software process may be unclear during process modeling, and (2) processes may change during enactment. In CSPL, process evolution can be achieved through (1) meta-process or (2) process program change. This article also describes object decomposition in CSPL, which relates to process evolution. CSPL allows decomposing large objects (software products) into sub-objects. With this, the schedule, budget, and developer of each sub-object development can be separately assigned and controlled. q 1999 Elsevier Science B.V. All rights reserved
