  Thanks so much for creating this graph. I know for a long time this model existed after reading Beer’s books in the ’90’s. But couldn’t find it back.

  The Analysis – Synthesis article suggests is from Decision and Control. Can’t remember reading that one, but I guess I did. 🙂 It’s a long time ago.

  Thanks!
