Use when building\n  an experimentation program, running growth sprints, prioritizing tests, or\n  establishing a data-driven growth culture. Triggers on: \"experimentation\",\n  \"growth experiments\", \"A/B testing program\", \"ICE scoring\", \"growth sprint\",\n  \"experiment design\", \"test velocity\", or any growth experimentation request.\nlicense: MIT\ncompatibility: Claude Code, Codex, GitHub Copilot, Cursor, Gemini CLI, OpenCode, Goose, Hermes, Jesse, Windsurf, Zed\nmetadata:\n  version: \"1.0.0\"\n  author: LeadMagic\n  category: analytics\n  tags: [experimentation, growth, testing, ice, sprints]\n  frameworks: [Sean Ellis Hacking Growth, Brian Balfour Reforge, Andrew Chen Growth, ICE Scoring]\n---\n\n# Growth Experimentation\n\n## Overview\nThe companies with the highest growth rates don't have better ideas — they\nhave better systems for testing ideas. A high-velocity experimentation system\nruns 15-30 experiments per month across acquisition, activation, retention,\nand monetization. Most experiments fail. That's by design. The team that\nlearns fastest from each failure wins.\n\n## When to Use\n- \"Build an experimentation program\"\n- \"Set up growth sprints\"\n- \"Prioritize experiments with ICE\"\n- \"Increase our test velocity\"\n- \"Create a learning repository\"\n\n## Authoritative Foundations\n- **Sean Ellis & Morgan Brown (Hacking Growth)** — coined \"growth hacking.\"\n  North Star Metric. Growth experimentation loop: analyze → ideate →\n  prioritize → test → learn.\n- **Brian Balfour (Reforge, ex-HubSpot VP Growth)** — increasing HubSpot's\n  experiment velocity from 5 to 20/week produced 3x growth rate improvement.\n  Four Fits Framework: Market-Product, Product-Channel, Channel-Model,\n  Model-Market.\n- **Andrew Chen (a16z, ex-Uber Growth)** — The Cold Start Problem. Growth\n  teams at scale.\n- **Fareed Mosavat (Reforge, ex-Slack Growth)** — experimentation systems.\n\n## Step-by-Step Process\n### Phase 1: Set the North Star Metric\nOne metric that captures core value delivery. If this moves up, the business\nis healthier. All experiments ladder to this metric.\n\n### Phase 2: ICE Scoring\nScore every experiment idea 1-10 on Impact, Confidence, Ease. Average the\nthree. Prioritize by ICE score. Re-score weekly as new data arrives.\n\n### Phase 3: Growth Sprint Cadence\nWeekly cycle: idea generation (Monday), prioritization (Tuesday), build\n(Wed-Thu), launch (Fri), analyze (Mon). 2-week sprints for complex tests.\nAI compresses cycle: a single growth marketer with AI can test 10 variants\nin time it used to take to build one.\n\n### Phase 4: Experiment Design\nEvery experiment: hypothesis, success metric, minimum detectable effect,\nrequired sample size, maximum duration. Document everything — winners\nand losers. Build a searchable learning repository.\n\n### Phase 5: 4 Layers of Experiments\n1. Channel/tactic assessment — test how channels impact conversions\n2. Offer optimization — pricing, packaging, trial length\n3. Message personalization — copy and creative by segment\n4. AI-powered — autonomous experiment generation, prediction, optimization\n\n## Output Format\nExperimentation system with North Star Metric definition, ICE backlog,\nsprint calendar, experiment design template, and learning repository structure.\n\n\n## Quality Check\n\nBefore delivering, verify:\n- [ ] All required sections are complete\n- [ ] Output matches the user's stated need\n- [ ] Named frameworks are cited for key recommendations\n- [ ] No vague claims — every recommendation has a specific action\n- [ ] Deliverable is ready for operational use, not just conceptual\n\n## Common Pitfalls\n1. **Tests too large** — redesigning entire onboarding (4 weeks to build)\n   loses to testing a single screen change (2 days). Small tests = fast\n   learning.\n2. **No learning repository** — running 50 experiments without documenting\n   learnings is running the same test twice. Document everything.\n3. **Statistical ignorance** — calling a test at 70% confidence produces\n   false positives. Wait for 95%+ confidence.\n4. **Winner's bias** — only shipping winners without understanding losers\n   means you don't know why things work.\n\n## Execution Artifacts\n\n- `references/framework-notes.md` — named frameworks, citation anchors, and operating assumptions\n- `templates/output-template.md` — copy-paste deliverable structure for the user\n- `scripts/check-output.py` — local checklist validator for required sections\nThis skill includes lightweight artifacts the agent can load on demand:\nUse the artifacts when the user asks for an implementation-ready deliverable, a repeatable workflow, or a quality check rather than generic advice.\n\n## Implementation Depth\n\nUse this section when the user asks for a finished asset, not a high-level explanation.\n\n### Diagnostic Questions\n\n1. What is the primary motion: founder-led, sales-led, product-led, partner-led, or lifecycle-led?\n2. Which ICP tier is the output for: small business, mid-market, enterprise, or mixed?\n3. What proof is available today: customer stories, usage data, third-party validation, screenshots, or none?\n4. What system will execute the work: CRM, sequencer, warehouse, support desk, product analytics, or manual workflow?\n5. What decision will the user make from this output: launch, prioritize, route, rewrite, score, coach, or measure?\n\n### Framework Application\n\nMap the recommendation explicitly to the named frameworks in this skill:\n\n- Sean Ellis Hacking Growth: apply only the part that directly improves the requested deliverable.\n- Brian Balfour Reforge: apply only the part that directly improves the requested deliverable.\n- Andrew Chen Growth: apply only the part that directly improves the requested deliverable.\n- ICE Scoring: apply only the part that directly improves the requested deliverable.\n\n### Deliverable Standard\n\nA strong output from this skill includes:\n\n- A crisp diagnosis of the current situation\n- A recommended path with tradeoffs, not a generic list\n- A concrete artifact the user can use immediately: table, script, checklist, scorecard, sequence, dashboard spec, or implementation plan\n- A measurement plan with leading and lagging indicators\n- Risks and edge cases called out before execution\n\n### Adaptation Rules\n\n- For small business: reduce complexity, shorten time-to-value, and prioritize owner/operator clarity.\n- For mid-market: include workflow ownership, handoffs, integrations, and enablement assets.\n- For enterprise: include governance, risk, procurement, stakeholder mapping, and proof requirements.\n\n\n## Related Skills\n- **a-b-testing**: Statistical framework for individual tests\n- **gtm-metrics**: Growth metrics and dashboard design\n","tagline":">-","category":"data-analysis","tags":["agent-skill"],"author":"LeadMagic","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"LeadMagic/gtm-skills","creatorName":"LeadMagic","creatorUrl":"https://github.com/LeadMagic","sourceUrl":"https://github.com/LeadMagic/gtm-skills/tree/main/skills/analytics/growth-experimentation","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/leadmagic-growth-experimentation#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
