This is a little embarrassing; and I promise I've done my homework; but I still get confused between Metrics and Decision Criteria...
I'm trying to simplify it my way of seeing it is:
Metrics are what we offer/propose to solve the Pain
Decision Criteria is how they define whether it solves the Pain or not
So in essence, the best Metrics have credibility, proof points, clarity etc... to make their Decision Criteria easier to meet.
But I'm still not sure. And there seems to be lots of blurred lines, grey areas and different interpretations.
Can anyone offer a better way?
