Which of the following is an advantage of prototyping?
A.
Prototype systems can provide significant time and cost savings.
B.
Change control is often less complicated with prototype systems.
C.
It ensures that functions or extras are not added to the intended system.
D.
Strong internal controls are easier to implement.
Explanation:
A sample of software code or a model (prototype) can be developed to explore a specific approach to a
problem before investing expensive time and resources. A team can identify the usability and design problems
while working with a prototype and adjust their approach as necessary. Within the software developmentindustry three main prototype models have been invented and used. These are the rapid prototype, evolutionary
prototype, and operational prototype.
Incorrect Answers:
B: Change control is not less complicated with prototype systems.
C: Prototyping does nothing to ensure that functions or extras are not added to the intended system.
D: Strong internal controls are not easier to implement with prototyping. Being a new/prototype system, strong
internal controls are likely to be more difficult to implement than a non-prototype system.Harris, Shon, All In One CISSP Exam Guide, 6th Edition, McGraw-Hill, New York, 2013, p. 1114
