The dashboard tree ideas is neat, but I think the bigger idea is the fusion of ToC ideas with the different dashboard levels, i.e goal, then CSFs then NCs. Very cool.

It sounds like there might be a homomorphism, although that might not be exactly the right concept, between the mental model of how the business works and/or a current reality tree. Need to think about this some more.

When I was trying to build dashboards it was obvious when you were mixing metrics at different levels and it doesn't feel right. It’s very much like programming - try to avoid mixing layers where possible.
