Questions and Answers

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)
