Sorai Sorai Decision-Grade Review

Glossary term

Diligence Audit Trail

A diligence audit trail is the chronological record of what was reviewed, what changed, who changed it, what evidence supported the issue, and how reviewers resolved it over time. It turns a diligence process from a collection of outputs into a record that can be explained and defended later.

Quick take

An audit trail is what makes a diligence record explainable after the live process ends.

Why it matters

Institutional deal teams need more than final outputs. They need confidence that the path from evidence to decision can be reviewed, challenged, and defended after the live deal pressure passes.
