C) Iterative

D) Non - iterative

 

Correct ans is A, How?

Answer 1

The Waterfall model can be perceived as reducing the cost of development in certain contexts, particularly if the project has well-defined requirements and minimal changes. Here’s how it can contribute to cost reduction:

1. Structured Approach: The Waterfall model follows a sequential, step-by-step approach, which ensures that each phase of development is completed before moving on to the next. This structured approach can help in managing and controlling costs effectively if the requirements are stable and well-understood.

2. Clear Documentation: Each phase in the Waterfall model produces detailed documentation and deliverables. This documentation can help in maintaining clarity about the project scope and requirements, reducing the likelihood of costly misunderstandings or changes later in the process.

3. Reduced Change Management: If the requirements are well-defined and unlikely to change, the Waterfall model can minimize the costs associated with change management and rework, as the model does not typically accommodate changes easily once a phase is completed.

However, it’s important to note that the Waterfall model may not always be cost-effective if requirements are likely to change or if there’s a need for frequent user feedback. In such cases, models like Prototyping or Iterative may be more suitable as they accommodate changes and feedback more effectively.

In summary, while the Waterfall model can reduce costs in projects with stable requirements, it may not be the best choice for projects where requirements are expected to evolve.
