What is the main advantage of the waterfall methodology over agile?

The main advantage of the waterfall methodology over agile is its structured and linear approach, which provides a clear, step-by-step process for development. This can be beneficial for projects with well-defined requirements and a stable scope, where changes are unlikely to occur.

The waterfall methodology ensures that each phase is completed before moving on to the next, reducing the risk of scope creep and providing a clear timeline for project completion. This approach is often preferred in industries where regulatory compliance and documentation are critical, as it provides a clear record of the development process from start to finish.
