  • Kill: The experiment showed no meaningful impact or negative trade-offs.


Learnings

Every experiment should provide insights, regardless of its success.

Key Learnings to Document:

  • What worked and why?
  • What didn’t work and why?
  • Unexpected behaviours or insights from user interactions.


Next Steps

Based on the learnings, determine actionable next steps.

Actionable Next Steps Framework:
