The software process is the total set of software engineering activities necessary to develop and maintain software products. Software process technology (SPT) deals with methods, formalisms, and tools for supporting the software process. SPT has developed into a key technology in terms of its importance to software engineering environments, systems integration, cooperative working, and business process re-engineering. This volume contains the proceedings of the third European Workshop on Software Process Technology. It is organized into six parts: architecture, meta-process and methodology, process modeling concepts, PML concepts and paradigms, experiences with SPT, and related domains.
