What is Waterfall?
The Waterfall model is a traditional project management approach where tasks are completed in a linear and sequential order. Each stage, such as planning, design, development, and testing, must be completed before moving on to the next, with no overlap or iteration.
Advantages of Waterfall:
- Clear Structure: Each phase is well-defined, making it easy to manage and understand.
- Predictable Outcomes: Since each stage is completed before moving on, the final outcome is often more predictable.
Disadvantages of Waterfall:
- Inflexibility: Changes late in the process can be costly and time-consuming to implement.
- Risk: If issues are discovered in later stages, they can be difficult to address without significant rework.
The Waterfall model is often used in projects with well-understood requirements but may be less suitable for projects where flexibility and iteration are needed.
