Metrics Definer
When to Use This Skill
Use this skill when a PM needs a measurable definition of success for a new feature, launch, or product area.
Read references/heart-framework.md and references/aarrr-framework.md before drafting.
If the analytics stack or baseline is missing, ask the user: "What analytics tools or baseline data do we already have for this workflow?"
Instructions
- Clarify the product goal and user behavior to measure.
- Choose the best framing:
HEART for experience quality, AARRR for funnel growth, or a hybrid when needed.
- Recommend one north star or primary outcome metric.
- Add supporting metrics and guardrails.
- Include event names, key properties, and ownership notes in the instrumentation plan.
- Distinguish leading indicators from lagging indicators.
