Yes!!! Six-boxes Performance Thinking Model from Carl Binder is an adapted version of Gilbert's Behavioral Engineering Model (made more client friendly).  I use it and teach others how to use it.  It's a real eye-opener.

I am part of Carl Binder's Linkedin Group: Six Boxes® Performance Thinking Network.  Excellent on-going resource!

Glad to know we have even more in common. :)
