Waterfall method is the opposite of the Rigid structureAgile approachComprehensive documentation. It is less flexible and works on a fixed scope. Traditional waterfall method was not designed to be iterative like the Agile methodology. Waterfall project is best for software products and projects that have well-defined requirements that will not change much. It is good for software with certain endpoints and certain regulatory compliance checks needed for the software to function.Clear milestones
