Over the past few weeks I have been reflecting on the concept of a Business Motivation Model and have thought about it in the context of physics as “cause”. The Business Rules Group attempted to create a Business Motivation Model, but I came to the conclusion they have failed. When they should have been attempting to create a notational system, they instead came up with a generalized business model.
The purpose of the “Why” focus in the Zachman Framework and correspondingly the Six Hats, Six Coats Framework, is to gauge the order of the system. The Green Hat row and Green Coat Column describe how legalistic the system is–how many causes a system contains.
The best way to think about the causality of a system is not business rules, but game theory. In particular, causality as a three dimensional network relating strategies. A good Business Motivation Model notation would allow the modeler to represent the strategies of all parties, how they interact and the expected outcomes. The Extensive Form Game notation is a good start but I think with some work I could come up with something better.
