In 2009, Forrester produced The Forrester Wave™: Collaboration Platform to evaluate a maturing vendor landscape for document collaboration solutions. Since that report, the market has seen significant disruption from consumer-focused offerings, cloud-based entrants, as well as repositioned offerings from traditional content and collaboration vendors. At the same time, demand for mobile document collaboration has resulted in new requirements that drive users to self-provision solutions if IT is not immediately responsive. This new chaotic vendor landscape coalesces around document collaboration, but vendors have very different strategies around the role of content in a knowledge worker's daily life. It is imperative for the CIO to understand vendor strategy in selecting the right solution.
