Our client, a city in California, hired Celerity to assist with the creation of a historical record of activities demonstrating compliance with procedures set forth by the National Security Agency (“NSA”). Celerity worked with various city departments to identify key custodians with potentially responsive data. Celerity then performed interviews and collection visits to further specify and capture the data. Paper documents were scanned and text was extracted using OCR. Electronic files were processed to extract metadata. The population was then loaded into Celerity’s web-based document review tool, OLIVER, and Celerity executed complex searches to organize the population into the issue categories desired by client attorneys. The resulting data was then converted into a format that could be searched and viewed using the city’s existing document review application.
