Plan a controlled feature rollout | DevPrompt Lab

A rollout workflow for reducing exposure while confirming behavior, performance, and data compatibility.

Reusable content

Create a staged rollout plan for the feature. Define the flag's default and owner, eligible audiences, rollout stages, health signals, minimum observation period, and disable procedure. Check whether old and new code can safely share the same stored data. Identify how the flag is removed after rollout and prevent stale branches from accumulating. Use metrics available in the system; do not invent thresholds. Include a rollback trigger and customer-support note.

Feature: {{FEATURE}}

Audience: {{AUDIENCE}}

Available metrics: {{METRICS}}

Disable path: {{KILL_SWITCH}}

How to use it

Feature flags do not replace authorization. Keep sensitive operations protected even when the feature is enabled.

Example

Stages: internal users, 5% cohort, 25%, then all users after error and latency signals remain within the agreed baseline.
