Waterfall Methodology
The Waterfall Methodology is a linear, sequential approach to software development where each phase must be completed before the next begins, typically including requirements, design, implementation, testing, deployment, and maintenance. It emphasizes thorough documentation and upfront planning, with minimal overlap between stages. This model is often contrasted with more iterative and flexible methodologies like Agile.
Developers should learn and use the Waterfall Methodology in projects with well-defined, stable requirements and low uncertainty, such as government contracts, safety-critical systems, or large-scale infrastructure where changes are costly. It is suitable when regulatory compliance, detailed documentation, and predictable timelines are priorities, as it provides a structured framework for managing complex, long-term projects.
