Natalia Connolly and Kevin Madura tested Claude Code on a replica of a post-merger procurement operation. The exercise covered more than 40,000 contract documents spread across disconnected databases, with hundreds of vendors shared by the merged businesses.
An audit found that Claude Code missed an amendment worth about $800,000 because it was not linked to its parent contract. It also gave December 1 as the deadline to prevent an automatic renewal, when the correct date was November 1.
The pair spent about 2 weeks building a 5-stage pipeline to extract terms, classify documents and rebuild contract relationships. They then gave Claude Code structured tables and reusable tools, putting business rules in code rather than prompts.
