Experiment Card

A falsifiable test card for one assumption — plan it, run it, log what you learned.

What it does

Turns one risky assumption — usually the top-left corner of an Assumption Map — into a Strategyzer test card: a falsifiable hypothesis, the cheapest test that produces real evidence, a metric to watch, and a numeric success criterion. The test itself runs outside this tool — an interview, a landing page, a concierge test.

When to reach for it

Right after an Assumption Map, for the assumption you are least sure of and would hurt most if wrong. One card per assumption — a risky map produces several.

Worth knowing

The hypothesis and the learning card are two different moments. Hypothesis, test, metric and criterion are the plan, written before anything happens; once the test has run, you fill in what you observed, what you learned, and what that means next — by hand, because the test happened outside this tool and no run can know the outcome for you.
