- Verify data rights — check provider terms, source permissions, privacy obligations, and regional requirements.
- Test representative records — measure coverage, accuracy, freshness, duplicate handling, and missing-data behavior.
- Set human checkpoints — require review before writing to a CRM, sending messages, or making qualification decisions.
- Measure economics — record time saved, data costs, conversion quality, and the effort required to maintain the workflow.
