CISSP PRACTICE QUESTIONS – 20201120

Which of the following approaches or practices delivers working software to customers least frequently?
A. Scrum
B. Prototyping
C. Minimum viable product (MVP)
D. Dynamic system development method (DSDM)

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is B. Prototyping.

This question is asking about “least frequently.” Prototypes are not working software. They will not be delivered to customers for production purposes and add no value from Agile’s perspective.

To deliver working software frequently is one of the Agile principles:

  • In Scrum, working software has to meet the definition of “done.” Each sprint produces an “increment,” or the total value of the delivered working software or solution.
  • Minimum viable product (MVP) is a common practice adopted in Agile that emphasizes “fail early, fail fast” to control risk. Subsequent releases may go on if the MPV is tested viable.
  • The dynamic system development method (DSDM) is an Agile approach as well. However, it is not as well-known as Scrum, XP, or Kanban nowadays.
