Why we ship in three weeks.
The three-week window is not an optimization. It is a constraint that forces honest scope. Here is what it does to a project when it is real.
Every project I take runs three weeks from kickoff to launch. Not five. Not eight. Not "three but we will see." Three.
Clients ask what happens if the scope needs more time. The honest answer is we cut scope. The window is the fixed variable. If a surface cannot ship at the quality I demand inside the window, it is not in version one. It is in the roadmap.
What the constraint does
Three things, mostly. It forces a real conversation about what matters in week one, when everyone is still fresh enough to be honest. It prevents scope creep in the middle, because there is no middle — every week is either the first or the last. And it pushes the work into a habit of finishing.
The enemy of a shipped website is not a bad designer. It is a week 14 that never ends.
Yes, there are projects that need more time. Those get quoted as a follow-on phase after launch, not as one endless drip.
