A Question for Practicing EAs

Why are you doing enterprise architecture?

If you don’t know the answer to this, how can you expect others to understand EA?

This is a simple question, but we are looking for comments from your readers to help others (without their answer) come up with the answer that meets their situation.  While everyone probably has a unique approach to the process, organization, and deliverables for EA; we find that the objectives of EA are similar across organizations.  You may not currently be fulfilling the reason why you are doing EA, but you have to at least know what you are TRYING to do.
