Build the plan around control points

Include access setup, integration configuration, data preparation, validation, cutover, monitoring, and handover. For each, write the entry condition, accountable owner, evidence of completion, and rollback or containment action. This prevents a status update from hiding a missing prerequisite.

Supabase’s official security guidance illustrates the principle: client-accessible data needs deliberate row-level policies, while server-side logic can sit behind an explicit function boundary. The correct pattern depends on the system; the plan must name the chosen boundary.

Illustrative rollout

Illustrative example. Names, volumes, dates and outcomes are fictional; replace them with approved evidence before use.

Week 1 creates a restricted test environment and validates identity mapping. Week 2 configures the read-only source connection and validates 30 records. Week 3 enables the agreed user group and reviews audit events.

The launch criterion is not ‘team trained’; it is ‘named users complete the defined workflow and the support owner accepts the runbook.’ The expansion criterion is separate.

Handover questions

• Who owns an access request after launch?
• Which system wins when two records disagree?
• What event starts an incident response?
• Where is the approved configuration recorded?
• What change needs a new customer review?
