Waterfall Requirements
Waterfall requirements refer to the formal, upfront specification of project needs in the Waterfall software development methodology, where all requirements are gathered, documented, and approved before any design or development begins. This approach emphasizes a linear, sequential process with distinct phases (requirements, design, implementation, testing, deployment) and minimal flexibility for changes once a phase is completed. It is often associated with detailed documentation, such as requirement specifications, to ensure clarity and reduce ambiguity in project execution.
Developers should learn about Waterfall requirements when working in regulated industries (e.g., aerospace, healthcare, or government) where strict compliance, traceability, and predictability are critical, as it helps ensure that all project deliverables are clearly defined and auditable. It is also useful in projects with stable, well-understood requirements and fixed budgets or timelines, as it minimizes scope creep and provides a structured framework for planning and resource allocation. However, it is less suitable for dynamic or innovative projects where requirements are likely to evolve.
