Waterfall is a traditional project management methodology that follows a linear approach to project completion. It is based on the idea of breaking down the project into distinct phases, with each phase having its own set of deliverables and objectives. The phases are typically sequential, meaning that one phase must be completed before the next can begin. This method is often used for large projects that require a high degree of control and predictability.
The main advantage of using the Waterfall methodology is that it provides a clear structure for managing complex projects. Each phase has its own set of tasks and deliverables, which makes it easier to track progress and identify any potential issues. Additionally, this method allows for better communication between stakeholders since everyone involved in the project knows what needs to be done at each stage.
One major disadvantage of using the Waterfall methodology is that it does not allow for much flexibility or adaptation during the course of the project. Once a phase has been completed, it cannot be changed or modified without starting over from the beginning. Additionally, this method can be time-consuming since each phase must be completed before moving onto the next one.
