Agile is a project management methodology that emphasizes customer collaboration, feedback, and adaptation throughout the project life cycle. Agile teams work in short iterations, called sprints, and deliver working increments of the product or service to the customer for review and approval. Agile teams can also respond to changing requirements and priorities by adjusting the scope, schedule, or quality of the project12.
Waterfall, on the other hand, is a project management methodology that follows a linear and sequential process, where each phase of the project must be completed before moving on to the next one. Waterfall teams work with a fixed scope, schedule, and quality, and deliver the final product or service to the customer at the end of the project. Waterfall teams have less customer involvement and flexibility during the project development34.
