Question

The advantage of better testing in software development is in 

• A. waterfall model
• B. prototyping
• C. iterative
• D. all of these

Answer 1

Incremental delivery not supported: In the iterative waterfall model, the full software is completely developed and tested before delivery to the customer. There is no scope for any intermediate delivery. So, customers have to wait long for getting the software.

So A and C are wrong.

 In this model, a prototype of the end product is first developed, tested and refined as per customer feedback repeatedly till a final acceptable prototype is achieved which forms the basis for developing the final product.

So B is correct.
