Waterfall Model | Vibepedia

The waterfall model is a software development methodology that follows a sequential and linear approach, where each phase of the development process is completed before moving on to the next one. This approach is among the least iterative and flexible, with progress flowing in one direction through the phases of conception, requirements analysis, design, construction, testing, deployment, and maintenance. The waterfall model provides a high degree of predictability and control, which can be beneficial for large and complex projects. However, its limitations have led to the development of alternative methodologies such as Agile. The waterfall model is often used in projects where requirements are well-defined and unlikely to change.
