It is not necessarily easy to evaluate the potential cost savings and the effectiveness of new technology. On the whole, eDiscovery exercises are done only once, and it is rarely possible to provide a side-by-side comparison between an exercise using one type of technology and a parallel exercise using another.

Winston & Strawn has been using Equivio Relevance technology – part of Equivio Zoom – for several years. At the request of a large institutional client, it conducted a project which applied Equivio Relevance to a set of documents which had previously been reviewed and coded; they estimated the time and costs required to use technology review over those documents in a defensible manner and compared the results of that process to a human review. The aim, amongst other things, was to conduct predictive coding exercise in the shortest possible time with the least amount of human review.

Winston & Strawn has written a paper about the exercise which is available on the Equivio website here.
