What is wrong with Figure 2.1 "The Waterfall Model" of the text book, and what changes need to be made to that diagram in order to enable a sensible course of action in our scenario.
Part C Explain the advantages of the waterfall method in three to five sentences. Give at least one example where the waterfall model is appropriate.
Part D Summarise the advantages of incremental delivery in about 3 to 5 sentences of your own words. Give at least one example where the waterfall model is inappropriate.
