Spec Driven Development
Spec first, then code
Every change starts with a proposal: what changes, why, and how you verify it works. Only when the specification stands do we write code. Boring? Maybe. Predictable? Absolutely.
Method
From proposal to proof
Specs are not paperwork after the fact — they drive the work.
1. Proposal
Every change starts with a short proposition: problem, scope and impact. Reviewable before anything is built.
2. Specification
Requirements with testable scenarios. Every requirement has a when-then that later becomes a test.
3. Implementation & proof
Code follows the spec, tests prove the scenarios, and the spec remains as living documentation.
In practice
This website was built this way too
We apply spec-driven working to applications, infrastructure and our own internal R&D tooling. Combined with Infrastructure as Code it means every environment and every feature traces back to a reviewed specification. That makes handover, audits and maintenance provably simpler.
