Tom Davenport’s Competing on Analytics was extraordinarily helpful when I was setting up supply chain, marketing, pricing, and competitive intelligence analytics teams inside Home Depot. His framework for how companies build analytics capabilities is spot on (we started at a low stage 2, and made it to a mid-stage 4) He’s still at it, and continues to be way ahead of the curve. Scott Brinker has a great summary of his talk at eMetrics here.
