Q1) Indicate the four phases of the waterfall approach and mention its advantages and disadvantages.
Answer: Waterfall is a sequential process that has each of the four phases (planning, analysis, design, and implementation)completed following the previous one. The two advantages are that requirements are identified long before programming and changes are minimized. The two disadvantages are an extensive paper trail and the time that passes from initial proposal and system completion.
Q2) Throwaway prototyping balances the benefits of well-thought-out analysis and design phases with the advantages of using prototypes to refine key issues before the system is built.
A)True
B)False
Answer: True
Q3) The waterfall development methodology derives its name from the salmon that swim up the waterfall against the current.

Q2) What is the difference between e-JAD and traditional JAD sessions? What makes e-JAD sessions more effective than the traditional ones?
Answer: In a traditional JAD session, only one person can talk at a time. With 10-20 participants, that means that everyone has to be silent most of the time. With e-JAD, special software on networked computers allows everyone to send ideas and opinions to everyone else anonymously. That way, all participants contribute at the same time, and since the input is anonymous, there is no fear of reprisal from challenging others. The research cited in the book suggests that e-JAD can reduce the time required to run a JAD session by 50% to 80%.
