A Framework for Clarifying Service-Oriented Notions - How to Position Different Approaches

Abstract

Definitions on Service-Oriented Architecture (SOA) and Service-oriented Design (SoD) are often not clear or even contradictory, which makes it hard to compare the various methodologies. We apply the Generic System Development Process (GSDP), a conceptual framework for developing systems of any kind, and specialise it for service-orientation. Using the resulting Service-Oriented Development Process, we position seven state-of-the art methodologies for service-orientation based on two criteria. One is the coverage of the system development process. The other criterion is the depth in which each of the development phases are dealt with.
