Steps, by experience

Beginner (under 1 year)

  1. Collect ideas for the priority funnel stage.
  2. Write each as a hypothesis with an expected result.
  3. Rank them by expected impact, confidence and effort.
  4. Run the top ones, one change at a time.
  5. Record every result and what you learned.

Intermediate (1 to 4 years)

  1. Maintain a ranked experiment backlog.
  2. Run experiments at a steady pace.
  3. Record and share learning.

Experienced (5+ years)

  1. Track experiment velocity and win rate.
  2. Combine learning into bigger product bets.
  3. Protect long-term value with guardrails.

Who can do this

Tool examples

Notion
Keep an experiment backlog with hypothesis, score, status and result.
Amplitude
Run experiments with guardrail metrics.

Definition of done

  • Ranked backlog in place
  • Experiments running regularly
  • Results recorded

Common pitfalls

  • Testing tiny changes with no real impact
  • Stopping tests early
  • Not sharing failures

If you lead the team

What good looks like: Growth teams keep a ranked experiment backlog and run tests steadily.

Ask your PM

  • How many experiments did we run last month, and what did we learn?
  • How do we rank the backlog?

Warning signs

  • Experiments are run one at a time, slowly.
  • Results aren't written up or shared.

Do these first
