spec-driven-workflow

Spec-first development requires writing a signed specification document with defined acceptance criteria before any code is written. This structured approach prevents scope creep and reduces ambiguity by ensuring all feature development is based on approved, testable requirements.

To implement a feature using a spec-first workflow, write a spec document defining acceptance criteria, generate test stubs from the spec, get customer sign-off on the requirements, and then write implementation code to make the tests pass.

Yes, spec-first development is intended for cross-functional teams working on complex customer-facing features or significant internal projects. It provides a structured approach to ensure requirements are testable and measurable before coding begins.

Spec-first development integrates directly with test-driven development by generating test stubs from the initial specifications. It enforces a test-driven approach where test cases must pass before the feature implementation coding is completed.

Requiring a signed spec document before coding ensures cross-functional teams have defined, measurable acceptance criteria. This mitigates scope creep, reduces ambiguity, and enhances collaboration by securing customer approval before development work starts.

A spec-first software development process should be avoided for minor changes lacking complex acceptance criteria. It is designed for complex projects requiring measurable requirements, making it too heavy for rapid prototyping or trivial code modifications.
