there are lots of similar activities like TOGAF
for example DoD and ministry of Treasury (of US) promote other architecture  frameworks.
once I tried all of them in part of IT strategic planning and none of them succeed. but I still think there are lots of good ideas in each one.

these are some other frameworks:

IEEE 1471-2000
Department of Defense Architecture Framework (DoDAF)
Ministry of Defense Architecture Framework (MoDAF)
and the well known Zachman

I am also eager to learn from any one who has applied any of the above or other similar architecture frameworks.
