This article assumes that Technology Assisted Review is being deployed in a production review setting where the user seeks to identify potentially relevant documents from among a larger corpus, and to subject those documents to full manual review. The use of TAR as an investigative or fact finding tool is a more financially flexible proposition, and the efficiency of that approach should be evaluated via separate standards.
There has been some debate in the past few years about the proper role of the Subject Matter Expert (SME) in technology assisted review (TAR) – a discussion which has understandably resulted in plenty of disagreement. There was a time when most blog posts and white papers swore that SME training was the only path to success, but that position looks to have softened some.
I have always been a bit skeptical of the necessity of SME training, especially when that SME takes the form of a law firm partner or senior associate. While a more compelling argument can be made for client insiders as SME trainers, I am not convinced that SME training is necessary in either case. There are two main factors that drive my opinion here – consistency and cost. Each of these factors must be carefully considered before embarking on a TAR project.
Proper planning is required to achieve consistency. However, consistency coming at a price tag that is greater than anticipated review savings is practically meaningless. The margin for cost efficiency between linear manual review and technology assisted review is thinner than you might think if you don’t carefully consider and control training costs.
