I've started to do this for social effectiveness. My map of all social skills is in the very early stages, but I hope to eventually granularize all social skills down to the level of specific exercises that can be done to train each sub-sub-sub-skill of social effectiveness.

Brilliant! I am somewhat tempted to do this for swimming, which (much more obviously, I think) consists of a long list of subskills that have to be learned through repetition before they can be put together.
