Waterfall and Agile are very different methods of project management that suit different project requirements. Agile is more suitable for projects where the stakeholders are very closely involved in every step of the project. On the other hand, the Waterfall model is more suitable for projects where you have a clear understanding of the project outcome right from the start; it does not offer too much flexibility and is a more structured model than Agile. Agile, as the name suggests, is best suited for teams that aim to move fast with a project and experiment in a specific direction despite not certainly knowing the outcomes of a project.
