Nowadays the interest in Business Process Management (BPM) and Service Oriented Architecture (SOA) is rising enormously. There are a lot of software developers and consultancy firms that are jumping to the occasion and are selling Business Process Management Systems (BPMS) that are based on these concepts (Hill, 2006). Hearing these companies talk, it is mostly about What the BPM and SOA concepts are and Why companies should start projects. Often the aim of such projects is turning a companys current application portfolio to a Service Oriented Architecture that can make the business more agile by using Business Process Management concepts and putting the business in the lead where it concerns the use of IT.
