The Waterfall methodology is a traditional, linear project management approach often used in software development. It emphasizes a sequential design process where each phase must be completed before the next one begins. Here are the core principles of the Waterfall methodology:

1.	Sequential Phases: The process is broken down into distinct, consecutive phases—typically requirements, design, implementation, testing, deployment, and maintenance. Each phase has specific goals and is completed before moving on to the next, with minimal overlap.

2.	Detailed Planning and Documentation: Extensive documentation is created for each phase. This ensures all project details, requirements, and deliverables are clear upfront, providing a roadmap for the entire project and helping manage expectations.

3.	Clear Requirements: Requirements are established and documented early in the project. The project team gathers and finalizes all requirements upfront, with little expectation for changes later. This makes Waterfall suitable for projects with stable requirements.

4.	Progress Measured by Milestones: Each phase serves as a milestone, making it easier to track progress. Only when a phase is fully completed does the team move to the next stage, ensuring a structured, linear progression.

5.	Limited Flexibility: Once a phase is complete, revisiting or altering it is often challenging and costly. This limited flexibility can make the Waterfall approach less suitable for projects where requirements may change or evolve during the development cycle.

6.	Testing After Development: Testing is usually concentrated toward the end of the development cycle, after the product has been implemented. This assumes that requirements were correctly captured and that minimal changes will be needed.

7.	Predictability: Waterfall’s structured approach and upfront planning provide a clear view of timelines, costs, and project scope. This predictability benefits projects that need a defined budget and schedule.

Waterfall is best suited for projects with well-understood, stable requirements, where change is minimal, and a predictable process is essential
