Final answer:
Three problems of the Waterfall model or method for software development are lack of flexibility, poor risk management, and inefficient progress tracking.
Step-by-step explanation:
Three problems of the Waterfall model or method for software development are:
- Lack of flexibility: The Waterfall model follows a sequential and linear approach, where each phase of the development process is completed before moving on to the next. This lack of flexibility makes it difficult to adapt to changing requirements or incorporate feedback during the development process.
- Poor risk management: The Waterfall model does not prioritize the identification and mitigation of risks early in the process. This can lead to issues and unexpected challenges surfacing late in the development cycle, which can be costly and time-consuming to address.
- Inefficient progress tracking: The Waterfall model relies on strict documentation and milestones to track progress. However, this can result in challenges in accurately assessing progress or making necessary adjustments if timelines or budgets are at risk.
