A promising approach, Object Management Group's (OMG) Model Driven Architecture (MDA), shifts the focus of software development from writing code to building models. It gives no guidelines on software implementation in terms of activities, phases, roles and responsibilities. Authors of this paper are offering an approach for enacting software development process with the help of process models. They are formalized with the help of Software Process Engineering Metamodel (SPEM), therefore the approach is called SPEM4MDA. The essence of approach is to use existing non-MDA process model formalized in SPEM notation, and with a help of another OMG initiative – Query/View/Transformation (QVT) – transforming it to MDA compliant process model.
