Product Velocity Without Breaking Things

You don't need a QA team to ship safely. You need a system.

The minimum stack

• Trunk-based development (no long-lived branches).
• One CI pipeline that runs tests + build + deploy.
• Feature flags for anything risky.
• One-click rollback.

Testing posture for tiny teams

You can't 100% cover everything. Focus on:

• Unit tests for pure functions only — domain logic, money math, parsers.
• Integration tests for the 5-10 critical user paths.
• Smoke test post-deploy that hits the home page + login + one core action.

Skip end-to-end frameworks until you're at 10+ engineers. They cost more than they save.

Feature flags

A flag for every meaningful change. Three states: off / on for staff / on for everyone. Defaults to off in prod.

The thing nobody tells you

Speed of shipping isn't a function of how many hours you put in. It's a function of how confident you are that a deploy won't break things. Confidence comes from the system, not the heroics.
