Here - have a title
The Deloitte article is all well and good and perhaps better than I would expect from consultants but ignores one crucial element. You have to have absolute faith in the numbers you're using. Any lack of faith, whether from statistical skewing, improper weighting of relevance or a whole host of other problems, will kill the confidence the decision maker has in his numbers. And we're back to good ole human intuition.
Billy Beane's baseball scouting methods only worked because he had a crack number cruncher who gave him numbers he had the confidence to trust and act upon. The doctors in Blink (God I hate that book) got lucky that the tree worked the first few times around and gave them the confidence to rely on it more. That thing about the wine is just nonsense though - but then again most of the Vintner biz is just nonsense anyway so I'll give it props.
I'm afraid I just don't have the same faith in most of the numbers that cross my desk.
