IT management has many facets, defining blueprints and guidelines for application architectures or planning the further development of the IT landscape are two typical examples. The BMW Group established four IT management processes for strategy, architecture, planning and control, which are linked to the IT project life cycle. But if these processes are not supported by an enterprise architecture management process, concentrating on the architecture on a holistic and abstract level, there still retains room for improvement. In this paper, we describe each process and how IT efficiency and IT effectiveness can be greatly improved by linking these processes using an integrated IT governance platform. We give some insights, which techniques are used in the processes, how the processes are linked and which functionalities for an integrated IT governance platform are needed.
