Waterfall project management methodology is a traditional approach to project management. It is based on the idea that each phase of the project should be completed before moving onto the next one. This means that all requirements must be identified and agreed upon at the beginning of the project, and then each phase must be completed in order before moving onto the next one. This method is often used for projects with well-defined requirements and objectives, as it allows for a more structured approach.
The main advantage of using this method is that it allows for a more organized approach to project management. By having all requirements identified and agreed upon at the beginning of the project, it makes it easier to plan out each step and ensure that all tasks are completed in order. Additionally, this method also helps to reduce risks associated with changes in scope or objectives during the course of the project.
One of the main disadvantages of using this method is that it can be difficult to make changes once a phase has been completed. If there are any changes needed after a phase has been finished, then it can be difficult to go back and adjust things without disrupting the entire process. Additionally, this method does not allow for much flexibility when it comes to adapting to changing conditions or customer needs.
