The model differs from other existing models in that it departs from the standard 5-level approach. It distinguishes 18 factors, called key areas, which are relevant to developing an architectural practice. Each key area has its own maturity development path(More)
Maturity models are a well-known instrument to support the improvement of functional domains in IS, like software development or testing. In this paper we present a generic method for developing focus area maturity models based on both extensive industrial experience and scientific investigation. Focus area maturity models are distinguished from fixed-level(More)
