Business Architecture (BA) sounds good but we still don't know what it consists of. Nevertheless, what we all want is a diagram showing how our Enterprise works, that is what are the key functions and flows of an Enterprise.

Here, http://www.enterprise-architecture-matters.co.uk/gods-business-architecture is a simple generic one page Business Architecture expressed in terms of key business functions and flows, I came with.
I'd like to use it for business operation discovery and documentation for my Enterprise Architecture work.
I would like to test your opinions about it.
