Two widely adopted approaches for the development of information systems are the Waterfall model and the Agile methodology. The Waterfall model is one of the traditional approaches to system development. It is a linear and sequential method, where the process flows downwards like a waterfall through distinct phases. These phases typically include requirements gathering, system design, implementation, testing, deployment, and maintenance. In the Waterfall model, each phase must be completed before moving to the next, ensuring that a structured and predictable development process is followed. The model is particularly useful when the system requirements are well understood from the outset and unlikely to change during development. However, it can be inflexible in dealing with changes in requirements and is often criticized for its lack of iterative feedback, which could lead to costly revisions if errors are discovered late in the development process. The Agile methodology, on the other hand, offers
