Winning is fun. To win we have to keep score. The way we keep score defines the game.

Success, like love and happiness, is an emergent property.  It cannot be measured directly. One can only measure its manifestations.

As the manifestation of success, growth has been used as the measure of success.  This has proven to be very problematical.One can grow with or without success.  Putting two turkeys together will not make an eagle.  To measure an emergent property, one has to measure more than one of its manifestations.  The best result is assessment of the future implicit in the present behavior.  To map this future, we need to get a handle on systems dynamics.

We know all too well how to play a zero-sum game.   We know how one can win here at the expense of there, or succeed today at the cost of tomorrow.  A new social calculus would create vertical, horizontal, and temporal compatability among members of an organization.
Interact methodology is one for creating such compability.
