spec-driven-development

Spec-driven development provides a structured workflow to write detailed specifications covering objectives, project structure, and testing strategy before coding begins. This approach clarifies requirements and prevents misunderstandings by validating plans thoroughly before implementation starts.

Managing a development workflow effectively is best achieved using a gated, four-phase process: Specify, Plan, Tasks, and Implement. This ensures thorough planning and validation at each stage, reducing ambiguity and keeping requirements well-defined and testable throughout the project lifecycle.

Maintaining a specification as a living document requires continuously updating the requirements as the project evolves. By treating the spec as an active reference, developers ensure that objectives, code style, and testing boundaries remain accurate and aligned with the current implementation state.

Spec-driven development works entirely without external dependencies, utilizing only internal scripts and reference components. It provides a self-contained workflow for creating, reviewing, and maintaining specifications, making it suitable for any software engineering environment regardless of the specific tech stack.

You should not use a specification-driven development process when requirements are completely undefined or rapidly changing without any baseline. This approach relies on creating detailed, testable boundaries and project structure documentation upfront, which requires a minimum level of project definition to be effective.
