The BABOK talk: The Core Concept Model, why include it?

The BABOK talk: The Core Concept Model why is it used? What the heck is the core concept model? Why did they include it in version 3 as the basis for all BA tasks. The core concept model is the way to look at all BA work, and all knowledge areas and tasks in the BABOK. It is the simplest way to think about everything we do and how we do it, in order to frame how to think about our work and how to think about what tasks or knowledge areas we need to use in a given context.
