18. (B) Which of the following is not an advantage of prototyping? a. Only basic system requirements are needed at the front-end of the project. b. End-prototype typically has more security and control features than a system developed with an SDLC process. c. Strong top-down commitment may be less necessary at the outset of the project. d.
