description: 'Build lean, opinionated products using the 37signals philosophy from "Getting Real", "Rework", and "Shape Up". Use when the user mentions "Getting Real", "Rework", "Shape Up", "37signals", "Basecamp method", "six-week cycles", "fixed time variable scope", "appetite vs estimates", "betting table", "breadboarding", "fat marker sketch", "build less", "underdo the competition", "opinionated software", "we have too many meetings", "how do we ship faster", or "stop overbuilding". Also trigger when cutting scope to ship sooner, running a small team, or avoiding long-term roadmaps. Covers shaping, betting, building, and the art of saying no. For MVP validation, see lean-startup. For design sprints, see design-sprint.'

# The 37signals Product Development Framework

A system for building profitable software without bloat, bureaucracy, or burnout, distilled from three books: *Getting Real* (build less), *Rework* (say no by default), and *Shape Up* (fix time, flex scope). Use it to shape work, bet on six-week cycles, run small autonomous teams, and ship on a predictable cadence.

## Core Principle

**Build less.** The best products do fewer things exceptionally well — simplicity is the destination, not the starting point. Traditional development adds; the 37signals way subtracts: build half a product (not a half-assed product), say no by default, fix the time and flex the scope. Constraints are what make great work possible — six weeks, three people, and a shaped pitch force you to find the essential version.

## Scoring

**Goal: 10/10.** Rate product plans, feature scopes, and team processes 0-10 against these principles. Report the current score and the specific changes needed to reach 10/10.

- **9-10:** Fixed-time cycles, shaped pitches, small teams, no backlog, opinionated defaults, clear copy
- **7-8:** Mostly shaped work and small teams, but some scope creep or process overhead
- **5-6:** Some shaping happens, but backlogs persist, teams are too large, or preferences replace decisions
- **3-4:** Heavy process (standups, sprints, story points) with occasional simplicity efforts… install to load the full skill
