Growth Experiment Design & Analysis
Design and analyze growth experiments with statistical rigor and actionable insights
What You Can Do
You can design hypothesis-driven A/B tests and multivariate experiments from scratch, complete with control group setup and success metric definition. Claude analyzes experimental results using statistical methods to determine significance, confidence levels, and effect sizes. You generate data-driven growth roadmaps and prioritize initiatives based on experiment learnings and metric correlations.
Features
Define clear hypotheses, control/variant groups, sample sizes, and success metrics for controlled experiments
Calculate p-values, confidence intervals, and effect sizes to determine if results are statistically valid
Transform raw experiment data into actionable insights with uplift calculations and business implications
Rank growth initiatives by expected impact, resource requirements, and confidence levels from experimental data
Create testable hypotheses based on funnel analysis, user behavior patterns, and data anomalies
Design complex experiments with multiple variables and analyze interaction effects between factors
Determine required sample sizes based on baseline metrics, desired uplift, and statistical power
Example Output
Example 1: A/B Test Analysis You provide: Control (8,500 impressions, 425 conversions) vs. Variant (8,200 impressions, 520 conversions)
Claude outputs:
- Conversion rates: 5.0% (control) vs. 6.3% (variant) = 26% uplift
- Statistical significance: p < 0.01 (>99% confidence)
- Recommendation: ✅ Launch variant — high confidence, low risk
Example 2: Growth Experiment Design You ask: "Design an experiment to improve free trial conversion"
Claude generates:
- Hypothesis: Removing credit card requirement increases trial-to-paid conversion by 8%
- Control: Current funnel (card required)
- Variant: Skip card, collect at conversion decision
- Metrics: Trial signup rate, trial-to-paid rate, churn
- Sample size: 5,000 per arm (28-day test)
- Risk factors: Chargebacks, fraud patterns
Example 3: Growth Roadmap You submit: Recent experiments on onboarding, pricing tiers, and referral bonuses
Claude prioritizes:
- Referral bonus expansion (45% expected impact, low cost, proven by experiments)
- Pricing tier optimization (18% impact, medium effort, high confidence)
- Advanced onboarding flow (12% impact, high cost, moderate confidence)

You can conduct rigorous material evaluations that integrate environmental impact data, cost implications, scalability constraints, and supply chain traceability into comprehensive comparison frameworks. This skill helps you move beyond marketing claims to develop evidence-based material profiles that support strategic sourcing decisions, substantiate sustainability claims to stakeholders, and align material choices with corporate sustainability targets and financial realities.

You can conduct comprehensive audits of fashion supply chains through a circular economy lens, moving beyond linear "take-make-dispose" models. This skill guides you through material flow analysis, infrastructure assessment, producer responsibility verification, and certification compliance—helping you identify whether suppliers genuinely support circular models or are greenwashing. You'll uncover financial viability barriers, benchmark circular maturity against competitors, and generate actionable audit reports for sustainability improvements.

This skill systematically searches your vault and Slack across specified time ranges to identify decisions using natural language patterns. It extracts decision context—including rationale, participants, dates, and sources—then matches decisions to projects and identifies gaps in your Decision Logs. You get a curated list of decisions that should be documented, reducing the risk of losing critical project decisions in the noise of daily communications.

You can transform disparate consumer signals—purchase behavior, social engagement, demographic shifts, and psychological motivations—into coherent trend narratives with actionable forecasting insights. This skill focuses on the why behind behavior rather than surface aesthetics, helping you identify inflection points where consumer preferences are shifting, validate collection strategy against actual psychology, and build predictive consumer profiles for 6-18 month forecasting horizons.

You'll transform raw consumer research, social listening, and feedback into actionable trend intelligence by decoding what consumers are actually thinking, feeling, and planning to do. This skill creates a standardized framework for interpreting sentiment data that reveals behavioral intention, emotional drivers, and adoption velocity—enabling you to spot emerging opportunities and category momentum shifts before they're visible to competitors.

This skill stress-tests your pitch narrative by analyzing story structure, identifying investor objections before they arise, and ensuring your message stays coherent across all deck sections. You'll get targeted feedback on narrative strength, compelling counterarguments to anticipated concerns, and audience-specific messaging variants that resonate with different investor profiles.

You can deconstruct supplier sustainability claims, identify hidden environmental costs across a material's full lifecycle, and compare alternatives based on equivalent functionality rather than isolated metrics. This skill helps you quantify trade-offs between sustainability dimensions—durability vs. water use, certifications vs. actual impact—so you can justify material choices to design teams, purchasing departments, and consumers with evidence-based reasoning.

You can strengthen your pitch narrative by tailoring messaging to specific investor types, identifying and preparing responses to likely objections, and practicing delivery with detailed feedback. This skill helps you transform a good pitch into a compelling one by analyzing your deck's structure, clarity, and persuasive impact.
