Specification Driven Development
Specification Driven Development (SDD) is a software development methodology that emphasizes creating detailed, formal specifications before writing any code. It involves defining precise requirements, behaviors, and constraints for a system using specification languages or tools, which then guide implementation and testing. This approach aims to reduce ambiguity, improve software quality, and ensure alignment with stakeholder needs from the outset.
Developers should use SDD in projects where correctness, reliability, and formal verification are critical, such as in safety-critical systems (e.g., aerospace, medical devices) or complex enterprise applications. It helps prevent defects early by clarifying requirements, supports automated testing through generated test cases, and is particularly valuable in regulated industries or when collaborating with non-technical stakeholders to avoid misunderstandings.
