Hypothesis Log Template

Track experiments from idea through validated learning.

A structured log for tracking product hypotheses through their full lifecycle: from initial assumption through experiment design, result capture, and next action. Keeping hypotheses in a shared visible log builds an organizational memory of what you've tested and what you've learned — preventing teams from running the same experiments twice and helping new members understand the evidence behind current decisions. Review it in quarterly planning to identify patterns in what's working.
