Decision records that survive a handoff.

Preserve the conditions behind the choice

A concise decision record captures the business output, considered alternatives, selected approach, and condition that would trigger a review. It also points to validation evidence and an accountable owner.

Make the record part of delivery

An AI-Ready Data Foundation Blueprint can establish the decision records needed for architecture, retention, ownership, and migration. Those records help a receiving team understand which assumptions remain valid and which require a new decision as the platform grows.
