EXPERIMENTATION FRAMEWORK

The Metric Bucket Framework

How to structure your experiment metrics so a "win" doesn't quietly cannibalize another part of your product. Straight from a Q&A with Dr. Simon Jackson (Cherto) at our Adasight × Cherto webinar, this playbook breaks down the four metric buckets — primary, secondary, guardrail, and learning — and the one technique most teams miss for catching cross-vertical cannibalization before it ships. Includes a worked example and a one-line decision rule your whole team can align on.

Intro: Get a practical framework for structuring experiment metrics so your team can actually trust every result.

✅ The four metric buckets — primary, secondary, guardrail, and learning — clearly defined
✅ The specific technique for catching cross-vertical cannibalization before you ship
✅ A worked example walking through a real scenario, metric by metric
✅ A one-line decision rule for aligning your whole team on ship/no-ship calls
✅ What to do when you can't run a clean A/B test

Why this matters

Most experimentation programs don't fail because they lack ideas: they fail because a "win" on one team's dashboard can quietly be a loss somewhere else in the business. The teams that scale experimentation aren't the ones running the most tests. They're the ones who've built the discipline to trust every result, even as more people across the org start shipping tests of their own. This framework is one piece of that discipline — the kind of practice that turns individual tests into a program that compounds.

This playbook is built directly from a live conversation: not just a summary of it.
