Lots of thoughtful discussion. I remain baffled by the raw material definition:

"Raw Material (e.g. metal, plastic, etc.) provided that it is readily available to all teams from standard distributors (e.g. McMaster-Carr, Home Depot, Grainger, etc.). The definition of Raw Material are items before being processed or manufactured into a functional form."

A tree would seem to be a raw material but what about a 2 x 4? I can argue either way.
