Design a Growth Hacking Experiment Plan

Design a growth hacking experiment plan for the following:

Business: [name and what it does]
Growth metric to improve: [signups / activation / retention / revenue / referral / other]
Current metric baseline: [current number or rate]
Target: [what you want to achieve]
Timeline: [how long to run experiments]
Team available: [solo / small team — describe roles]
Tech stack: [relevant tools and platforms]
Budget for experiments: [monthly range]
Biggest growth blocker currently: [what is preventing growth]
Previous experiments tried: [what has been tested — describe results]

Build a complete growth experiment plan:

GROWTH FRAMEWORK:
- AARRR funnel assessment (Acquisition / Activation / Retention / Referral / Revenue)
- Where the biggest lever is in the funnel right now
- Primary metric to move (the one that unlocks everything else)
- North Star Metric definition

EXPERIMENT BACKLOG (20 experiments):
For each experiment:
- Experiment name
- Hypothesis: "If we [change X], then [metric Y] will [increase/decrease] because [reason]"
- Funnel stage targeted
- Expected impact (High / Medium / Low)
- Implementation effort (Low / Medium / High)
- Priority score (impact / effort ratio)
- How to measure success
- Minimum viable test design
- Time to run

EXPERIMENT DESIGN FRAMEWORK:
- How to structure an A/B test correctly
- Statistical significance requirements
- Sample size calculation approach
- Test duration guidelines
- How to avoid common testing mistakes

QUICK WINS (run first):
- Top 5 experiments ranked by effort vs impact
- Full test plans for each:
  - What to change
  - Control vs variant
  - Success metric
  - How to implement
  - How to read results

EXPERIMENT OPERATIONS:
- How to document and track experiments
- Team review cadence
- Decision rules (when to ship / iterate / kill)
- How to share learnings
- Compounding experiments (how wins stack)

GROWTH CALENDAR:
- Sprint structure (2-week experiment cycles)
- Month 1 experiments
- Month 2 experiments
- Month 3 experiments
- Quarterly review and strategy reset
