SAP has worked with Cap Gemini and the Open Group to customize TOGAF to account for packaged solutions and Enterprise Services Architecture. Its obvious that SAP has put some thought into the SEAF.

I have since I was a young boy been fascinated with building architecture. That interest was the foundation of my passion for architecture as it applies to information technology. Being the son of a carpenter gave me plenty of opportunities to see how buildings are built and evolved. I have taken that perspective and applied it to my work in information systems architecture. So as I was rereading How Buildings Learn by Stewart Brand, I was struck by a most profound quote
A building is not something finished. A building is something you start.
