Presentation
Enterprise Architecture – A Governance Framework
While the dimensions of defining an enterprise architecture model – business, information, application and technical – have been fairly well established over the last years and appear in most models, there is much less clarity about how to govern enterprise architecture.

InfosysExperience with many of our clients indicates that governance is not only the more difficult part to get right, but also determines the impact of the architecture team to a far greater degree. Complaints about ivory tower architecture and shelfware production from the IT community, as well as about a lack of influence from architects, indicate that the effectiveness of governance is of uttermost importance for success.

We propose to describe and manage this governance along six dimensions: Leadership, people, processes, policies, metrics, and funding. The session expounds the relevancy of these dimensions for understanding and improving the impact of an architecture group, and describes best practices for implementing them.
