Launch Decision: Sticker-Reply Feature for Facebook Groups
Context
You are evaluating whether to launch a sticker-reply feature in Facebook Groups. The feature allows members to reply to posts or comments with a sticker (a lightweight, expressive response) in group threads.

Tasks
- State clear objectives and hypotheses for the feature.
- Define success metrics (primary and secondary) and guardrails.
- Propose an experiment design, including assignment unit, ramp, duration, and power.
- Describe how you would analyze the results and decide whether to launch.
- Call out key trade-offs and risks.
