Cases when Waterfall does not work
- Complex and Uncertain Requirements: Waterfall is not suitable for projects with rapidly changing or unclear requirements. In such cases, the sequential nature of Waterfall can lead to delays and rework. Agile methodologies, which emphasize flexibility and adaptability, are better suited for these situations. According to a study by Standish Group, 71% of projects failed due to poorly defined requirements, which is a common challenge for Waterfall projects.
- High Risk and Uncertainty: Projects that involve high levels of risk and uncertainty are not well-suited for Waterfall. The rigid nature of the Waterfall model makes it difficult to accommodate unexpected changes or adapt to new information. Agile methodologies, such as Scrum or Kanban, allow for frequent iterations and feedback, enabling teams to mitigate risks and respond to uncertainties more effectively.
- Long Development Cycles: Waterfall is not ideal for projects with long development cycles. The model assumes that all requirements can be gathered and defined upfront, which may not be feasible for projects that span several months or years. As a result, stakeholders may have to wait a significant amount of time before seeing any tangible results. Iterative approaches, like Agile or Lean, provide more frequent deliverables, ensuring continuous value delivery throughout the project.
- Limited Customer Involvement: Waterfall projects often have limited customer involvement until the later stages of development, typically during the testing or implementation phase. This can lead to misalignment between the final product and customer expectations. Agile methodologies emphasize regular customer collaboration and feedback, ensuring that the end product meets customer needs and preferences from the early stages of development.
- Minimal Adaptability: Waterfall does not handle changes well once the project is in motion. If there is a need to modify requirements or make adjustments, the entire project timeline and deliverables may need to be revised. This lack of adaptability can be problematic in dynamic environments where change is inevitable. Agile methodologies, on the other hand, embrace change and provide mechanisms to incorporate modifications without disrupting the entire project.
