What are the differences between iterative design and the waterfall model?

What are the differences between iterative design and the waterfall model?

The waterfall model is a linear approach where each phase must be completed before the next begins, while iterative design allows for repeated cycles of development and feedback.

Which model is better for software development?

It depends on the project. Iterative design is often better for projects needing flexibility and frequent updates, while waterfall can work well for projects with clear, unchanging requirements.

Can you give an example of when to use each model?

Sure! Use waterfall for projects like building a bridge, where requirements are fixed. Use iterative design for software apps, where user feedback is crucial.

What are the pros and cons of each model?

Waterfall's pros include clear structure and documentation, while its cons are inflexibility. Iterative design's pros are adaptability and user involvement, but it can lead to scope creep.
