The knife: scope as a weapon
Keep three. Kill the rest. The knife is not taste. It is how you buy stillness, a demo, and a sentence.
Scope is the only resource you actually control. Teams that 'just add it, it's small' donate the prize to someone meaner.
Thesis
Why this paper exists
Feature lists are how anxiety dresses up as ambition. The winning slice is almost always embarrassingly small and painfully specific.
- Cut a feature list to three under time pressure
- Know which three: the turn, the proof, the residue
- Use 'not this weekend' as a complete sentence
Three chairs
Every 36-hour product gets three chairs. Chair one: the turn — the moment the constraint becomes the feature. Chair two: the proof — the one action that makes the turn undeniable. Chair three: the residue — sentence, still frame, answer to 'this exists'.
Auth, settings, onboarding, dark mode, a second persona, a leaderboard, 'we'll just hook up Stripe' — none of these get a chair unless they are the turn. They are not.
Not this weekend
Say it out loud. Write a 'Monday' list so the ambitious teammate can see their idea was heard and scheduled for a life you are not living until 18:00 Sunday. The Monday list is a psychological hack on your own team.
If everything is the weekend, nothing is. The knife is how you stay kind to the person you will be at hour 30.
Specificity is the edge
A handover tool for nurses is a field idea. A three-line card the night nurse reads before she takes the keys — name, last insulin, the one thing that will kill someone — is a slice. Judges can feel the difference in the first fifteen seconds because one of them has a body.
Whenever a feature fight starts, ask: which chair does this sit in. If you cannot seat it, it is Monday.
Drill
Take a product with too many tabs. Seat three chairs. Write a Monday list of everything you love and will not touch. Timebox the argument to twelve minutes.
