Those of us who have spent years studying “data smart” companies believe we’ve already lived through two eras in the use of analytics.

In contrast to, say, a 1.1 version, a 2.0 product is a more substantial overhaul based on new priorities and technical possibilities. When large numbers of companies began capitalizing on vast new sources of unstructured, fast-moving information—big data—that was surely the case.
