Software Engineering Waterfall Model Quiz

What is the main purpose of system prototyping?

To check the customer's requirements and the feasibility of some design decisions (correct)
To reduce the number of requirements change proposals after delivery
To support both change avoidance and change tolerance
To develop the full system quickly

How does incremental delivery support change avoidance and change tolerance?

It allows for early delivery of the full system
It prevents the need for experimentation with the system
It reduces the cost of incorporating changes into later increments (correct)
It increases the number of requirements change proposals after delivery

What is the main purpose of a software prototype?

To develop the full system quickly
To demonstrate concepts and try out design options
To find out more about the problem and its possible solutions
All of the above (correct)
