Which of the following methodologies might be most appropriate if you have a system project with:unclear user requirements; unfamiliar technologies; somewhat complex; needs to be reliable; time isnot an issue and the schedule visibility is somewhat important? a) Waterfall
b) Parallel
c) Iterative
d) System prototyping
e) Throwaway prototyping

Throwaway prototyping

Explanation:

Waterfall is used when the system has clear requirements, reasonably reliable, very familiar technologies, isn't too complex. It's also used when there's a very long time schedule and in a scenario whereby the schedule visibility isn't important.

Parallel is used when the system project has clear requirements, shirt time schedule, technologies that are very familiar, not all that complex; reasonably reliable, and the schedule visibility is not important.

With regards to the question, the description given fits a throwaway prototyping. Therefore, the correct option is E.
