One of the most common topics we are consulted on is the production and review of ESI. Small firms in particular face difficulties in thoroughly investigating ESI while minimizing costs. The author of this article, Craig Ball, issued the EDna Challenge in 2009 in order to address this issue. The challenge sought a product that could equip a small firm lawyer to competently process and review a small amount of run-of-the-mill ESI. One product met all the criteria of the challenge as well as being substantially cheaper than any competing products: Prooffinder. The article discusses the advantages of Prooffinder and what it can do for the small firm lawyer.
