Quizplus · Accepted Answer

All three options are significant disadvantages with the waterfall development methodology. The long time elapse between the proposal and system delivery can make the system outdated before it even gets delivered. If the team misses important requirements, noteworthy amounts of programming effort may be needed post-implementation, which can be both time and money intensive. The design must be fully specified on paper before programming can start, which can be inflexible and lead to potential errors. These are all important points that put forth the limitations of the waterfall methodology.
