I say "finally" because most of the ideas for these documents were collected during the research Diego Lo Giudice and I did for Forrester's EA Forum 2010, nearly one year ago. If the ideas are quick to come, they sometimes take a long time to be realized in a document! I apologize to the customers who were waiting for the final document.
The goal of this collection of documents is to demonstrate typical EA involvement in IT governances — an area that is usually more or less "beyond" EA's scope. We also said in the EA Forum presentation that these potential involvements are not mandatory and highly depend on your particular EA objectives. EA involvement in IT governance should remain in line with the recommendation we made in Forrester report "Avoid The EA Governance Versus Agility Trap" and in which we still continue to believe: Governance is a lever to obtain nonshared (or even diverging) objectives. When objectives are shared, then governance is not required, and the approach should remain agile.
