The 90-Second Test
A simple heuristic for cutting features: if it doesn't earn its place in the first ninety seconds, it doesn't ship.
When I joined Quill we had a feature list with forty-three items. We launched with eleven. The cuts came from a single question: does this earn its place in the first ninety seconds of a new user's session?
Ninety seconds is roughly the amount of time a curious person will give a new tool before deciding whether to keep going. Anything that doesn't show up in that window — or worse, gets in the way of the thing they came for — is a future feature, not a launch feature.
This isn't a rule. It's a forcing function. Most teams know which features are weak; what they lack is a clean reason to cut them. Ninety seconds gives you one.
