Customized Culling: how E-STET reduced a review population from 6m to 80,000

Customized Culling Process

Working knowledge of how a company operates, including its IT infrastructure and organizational chart, can be very valuable in customizing eDiscovery workflow in each case. A one-size-fits-all approach does not bring real value to a client and its legal team.


The Challenge

A long-time client had collected and processed over 6 million documents for a recent consumer class-action lawsuit. The client and opposing party were unable to reach agreement on a keyword filter, with the client complaining that all proposals were overly broad. The best keyword filter resulted in almost 2 million documents and a random sample of these showed that less than 5 percent would be potentially relevant. Time and money were both in limited supply.


The Solution

E-STET created a search matrix of highly specific searches limited to targeted custodians, media sources, date ranges, file names, project names, and other keywords and key individuals that were identified after some sample document review. E-STET tracked each search and all of the results so that the client could defend the process to the opposing party. Some additional searches were added at the request of the opposing party and agreement was reached using this very customized approach to document culling.


The Result

E-STET was able to reduce the review population from 2 million documents to 80,000 documents. Time spent performing culling searches was well worth it to reduce the review numbers by 96 percent.
