The Experiment Tracker makes the build-measure-learn cycle visible and disciplined. By tracking Hypotheses, Experiments, Learnings, and Evidence in parallel columns, teams build a scientific record of what works, what doesn't, and why.
What have we tested, what did we learn, and what evidence supports our decisions?
Track the full validation pipeline from hypothesis through experiment to validated learning. A four-column Lean Startup board that ensures every idea is tested before being committed.
Common in growth and product teams running continuous experiments.
Every hypothesis should have a testable prediction: "We believe X. We will know this is true when we see Y." Design experiments with the smallest footprint possible. Move cards from Hypotheses to Experiments only when you have a concrete test designed.
Don't treat experiments as features — they're probes, not promises. Avoid running too many experiments simultaneously; focus gives better signal. Don't skip the Evidence column — undocumented learnings evaporate when teams change.
