Check that every roadmap item names an outcome. Runs in your browser, no sign-in, and your work is saved on this device.
Your result
Add an item and finish its “so that” sentence to see the verdict.
Why this works
The lesson behind the tool
Output is the polished brass: hours logged, features shipped. Outcome is the ship that didn't hit the rocks. Customers never see your logbook; they only feel whether they got home safely.
Finishing “We're building this so that…” for every item forces the outcome into the open. And hand engineers the storm, the rocks and the ships, and they'll invent better light than any feature list.
