Traditional Requirements Engineering
Traditional Requirements Engineering is a structured, systematic approach to identifying, documenting, analyzing, and managing software requirements early in the development lifecycle. It emphasizes thorough upfront planning, formal documentation, and stakeholder consensus to define clear, stable specifications before design and implementation begin. This methodology is often associated with waterfall or plan-driven development models, where requirements are treated as a fixed foundation for subsequent phases.
Developers should learn and use Traditional Requirements Engineering when working on large-scale, safety-critical, or highly regulated projects (e.g., aerospace, medical devices, or government systems) where clarity, traceability, and compliance are paramount. It helps minimize misunderstandings, reduce rework, and ensure alignment with business goals by establishing a detailed baseline before coding starts. However, it is less suited for fast-paced, iterative environments where requirements are expected to evolve frequently.
