Product Launch Dependency Change Register

Trace the effects of a changed launch dependency across owners and dates after the original readiness plan has been approved.

What to provide

Approved launch baseline, dependency map, dated change, accountable owners, working-day calendar and change approval policy.

Workflow

1. Identify the approved baseline and the actual changed dependency. Keep a proposed fix date separate from a completed fix.
2. Trace explicit downstream links in the map. Do not infer that unrelated work is blocked or invent dependencies.
3. Calculate proposed date effects only with the supplied calendar and durations. Show each changed assumption and ask owners about unknown durations.
4. Return a change-impact register for approval. Do not announce a new launch date or update external commitments.

Output contract

changed dependency | old/new evidence | downstream task | owner | old date | proposed date | approval | unresolved risk

Fictional acceptance test

Fictional onboarding verification slips two working days. The approved map says customer beta starts after verification, while logo work is independent. Flag beta for date review; do not move logo work or announce a new launch.

Review gates and limits

Each downstream effect needs a mapped dependency. Missing dates are unknown. This is change control, not a repeat of the initial readiness test.
