Feature Flag Rollout and Rollback Plan Builder

Design a safe production rollout plan with feature flags, exposure stages, monitoring thresholds, and rollback triggers.

Prompt Template

You are a senior release engineer. Help me design a feature-flag rollout and rollback plan for:

Feature description: [what is being launched]
System type: [web app, mobile app, API, backend job, etc.]
User segments affected: [beta users, enterprise accounts, region, plan tier]
Risk level: [low / medium / high]
Dependencies: [services, database changes, third-party APIs, mobile app versions]
Primary success metrics: [activation, conversion, latency, crash-free sessions, error rate]
Guardrail metrics: [support tickets, payment failures, performance degradation]
Rollout tools available: [LaunchDarkly, custom flags, config service, etc.]
Team on call: [roles and hours]

Provide:
1. Recommended rollout stages by percentage or segment
2. Pre-launch checklist including instrumentation and kill switches
3. Guardrail thresholds that should pause the rollout
4. Rollback decision tree for incidents and degraded metrics
5. Communication template for engineering, support, and stakeholders
6. Post-launch review checklist and feature-flag cleanup plan
7. Sample incident timeline for a failed rollout

Example Output

Rollout Plan

Exposure Stages

1. Internal staff only for 24 hours

2. 5% of low-risk customers in one region

3. 25% of self-serve accounts

4. 50% of all eligible traffic

5. 100% after 48 hours of stable guardrails

Pause Thresholds

- API p95 latency rises more than 20%

- Checkout conversion drops more than 5% vs control

- Support tickets tagged to the feature exceed 15 in 2 hours

- Crash-free sessions fall below 99.3%

Rollback Tree

If revenue-impacting bug is confirmed, disable the flag immediately, post incident status in Slack, and preserve logs before retrying.

If only one segment is affected, roll back that segment first and continue investigation before global disable.

Cleanup Reminder

Set a hard deadline to remove the flag within 2 sprints after stable launch so temporary release logic does not become permanent technical debt.

Tips for Best Results

💡Name your success metrics and guardrails separately, teams often track only upside and forget safety signals
💡Include mobile app version constraints if relevant, feature flags do not magically fix incompatible clients
💡Ask for a communication template, clean rollout ops are as much coordination as code
