Product Management playbook/Module 6 · Evidence

Day 59 / 100 · Evidence · Fake doors and painted doors

Measure demand before you build.

Put the entrance to a feature in front of customers before the feature exists, and count who tries to walk through.

How it works

A button, menu item or plan option for something not yet built.

What it measures

Real interest, from real customers, in context.

Be honest right away

After the click: “Coming soon. Want early access?”

Keep it short

Days or weeks, not months. Then decide.

Never for: billing, security, or anything where a fake option could cause real harm or confusion.

Test interest with honesty.
