01
Build
Make the smallest end-to-end slice. A rough product teaches more than a polished plan.
Software methodology
Working software is the source of truth.
Build First is how small teams ship great products. Start with something that works, show it early, and refine it against reality.
Dan McCarey · Version 1.0 · November, 2026
02
Show
Put it in front of the team, and soon a user. Everyone reacts to the same real thing.
03
Refine
Change what you just learned. Keep what held up. Then run the loop again.
Build First is a living document.
The pages that follow are the methodology itself: why it exists, how it differs from Agile, Scrum, and Shape Up, and the workflow a small team can use on Monday.
