SmartData Collective has a nice entry-level piece on thinking about decision management here.

The cheat sheet:

1.  Implement rules and observe closely, then lather, rinse, repeat.

2.  Measure constantly.

3.  Look beyond your KPIs (key performance indicators) for what they aren’t telling you.

4.  Be creative. (Easier said than done).

5.  Evaluate your results from ex-ante expectations.
