What is Waterfall in Project Management?

Waterfall is a structured project management methodology that follows a linear and sequential approach to completing projects. It is called "Waterfall" because work flows downward through distinct phases, similar to a waterfall. The typical phases include Requirement Gathering, Design, Implementation, Testing, Deployment, and Maintenance. Each phase must be completed before moving to the next, and changes are difficult to accommodate once a phase is finalized. This method is best suited for projects with clear objectives, well-defined requirements, and minimal uncertainty, such as construction, manufacturing, and software development with strict compliance needs. The advantages of the Waterfall model include detailed planning, clear documentation, and a structured process that ensures stability and predictability. However, its main drawback is its inflexibility, making it less suitable for projects requiring frequent adjustments. While Agile methodologies have gained popularity for their adaptability, Waterfall remains a reliable choice for projects that require a rigid, step-by-step approach with well-established goals and deliverables.
