I think this is the way forward and to take it a step further, iterative exploratory data mining/analysis is the way to go(according to me).

There is a lot of value in getting a list of all the data you can gather, having the business people explain it to the techies, putting your heads together and coming up with ad-hoc queries and data cuts that provide any insight. There is a disconnect between what data can be gathered which when combined with existing metrics leads to a-ha moments.

Targeting works but in very complex/unexplored business ecosystems it might be better to go rogue to get "quick wins".
