Have you applied the waterfall methodology in your projects?

Yes, in some projects I have applied the Waterfall methodology. This approach involves sequentially completing development phases: requirements gathering, design, implementation, testing, and support. Each phase is fully completed before moving on to the next.

The Waterfall approach is well-suited for projects with clearly defined requirements and minimal changes during development. However, it is less flexible compared to iterative methodologies like Agile and may be inefficient in environments with rapidly changing requirements.
