Questions and Answers

What is the purpose of prototyping in software systems?

  • To test and experiment with system designs
  • To construct a partial implementation for production use
  • To develop a complete version of the system
  • To help elicit and validate system requirements (correct)

    • What is the main characteristic of a prototype in hardware systems?

  • It is easy to develop quickly (correct)
  • It is a complete version of the system
  • It is intended for production use
  • It is used to elicit system requirements

    • What is the main advantage of using prototyping for requirements elicitation?

  • It makes the system available early in the development process
  • It helps in developing the complete system
  • It allows users to experiment with the system (correct)
  • It provides a subset of the system
