Editor’s Note: Originally published in June of 2019, this update on eDiscovery collection task, spend and cost information contains new data points based on recent refreshes of industry market sizing research and eDiscovery service pricing surveys from ComplexDiscovery. This updated information may be beneficial for legal, business, and IT professionals considering the business of eDiscovery and specifically the economics of eDiscovery collection.

A 2020 Look at eDiscovery Collection: The Task

Within the context of data discovery and legal discovery, the task of collection consists of locating potential sources of electronically stored information (ESI) and gathering ESI for further use in the eDiscovery process. It is one of three tasks, that along with processing and review, make up the core tasks typically associated with the process of eDiscovery.

In considering the relative costs of the three core eDiscovery tasks of collection, processing, and review, in 2012, the task of collection represented approximately 8% of the total expenditure for eDiscovery tasks, with processing representing 19% of expenditures and review representing 73% of expenditures. (1) Based on market modeling since 2012, the current relative cost of the eDiscovery task of collection in 2020 has increased and is now estimated to be 13% of expenditures. Additionally, in 2020, the core eDiscovery task of processing is currently estimated to represent 19% of expenditures, and the core eDiscovery task of review is estimated to represent 68% of expenditures.

Collection Pricing Data Points: The Cost

While many individual elements contribute to the cost of collection, results from the semi-annual eDiscovery Pricing Survey (4) may provide insight into three key costs and cost trends related to the eDiscovery task of collection.
