spec-driven-development

Spec-driven development is a structured approach requiring a complete specification before coding to ensure team alignment. By drafting objectives, project structure, and testing strategy upfront, it prevents ambiguity and scope creep throughout the software engineering process.

Drafting a structured specification involves defining objectives, commands, project structure, code style, and testing strategy. This process ensures clear consensus among stakeholders and engineers before any implementation work starts on the project.

Yes, the specification functions as a living document that updates as decisions evolve. It maintains alignment between engineers and stakeholders by reflecting changes throughout the gated, phase-based implementation workflow.

The phase-based specification workflow gates work through SPECIFY, PLAN, TASKS, and IMPLEMENT phases. This enforces a structured progression from initial requirements alignment to actual coding, ensuring clear consensus at each stage.

Spec-driven development works by defining objectives and acceptance criteria before implementation, which applies to both new and existing projects. The living document adapts as decisions change, maintaining alignment regardless of project maturity.

Using a living spec ensures clear consensus between engineers and stakeholders by defining boundaries and testing strategy upfront. It prevents ambiguity and scope creep by enforcing a gated process from specification to implementation.
