Describe why, in terms of the amount of effort required, the interactive approach is preferable than the waterfall model.

Where can I get a description of the stages that are involved in the iterative waterfall model? Another possible alternative that might be used is referred to as the Iterative Waterfall Model. Could you please elaborate given this circumstance? What do you think the appropriate answer is, in your opinion?

Spiral model outperforms waterfall approach in three ways. Compare. Kindly explain your response.

What I need from you is a three-point argument demonstrating why the spiral model is superior to the waterfall approach.
