Case Study: Complete Discovery Source reduces manual review by 85% with Relativity

CDS Reduces Manual Review by 85%

Complete Discovery Source was engaged by a large financial services client facing a government demand to quickly produce documents. What began as a 100,000‑document review from three custodians suddenly tripled when a fourth custodian produced 200,000 more, creating a 300,000‑document universe and a severe time‑and‑cost challenge. Complete Discovery Source deployed Relativity's Assisted Review to accelerate prioritization and limit manual review.

Using Relativity, Complete Discovery Source seeded the model with previously coded work, ran 13 Assisted Review rounds combining targeted keyword sampling and random checks to guard against false negatives, and iteratively retrained the system. Reviewers examined only 29,000 documents (229 responsive), more than 170,000 documents were confidently designated non‑responsive, manual review dropped to less than 15% (≈85% reduction), and the approach saved hundreds of attorney hours while meeting the production timeline.
