Problem 4 (designed to be used with the NORMDIST tutorial) Because of a competitor's action, top management has asked R&D to speed up the process of bringing to market a new high resolution digital camera. The predecessor and activity time estimates (in months) are shown in the following table, Immediate predecessor(s) Activity A B D E F G A B, C B C,D,E F Optimistic time 1 3 1 3.5 4 6.5 5 Most probable Pessimistic time time 1.5 5 4 5 2 3 5 6.5 5 12 7.5 11.5 9 13 a. Construct the appropriate network diagram. b. Indicate the critical path. c. What is the expected completion time for the project? d. Management estimates that securing "first mover" status means having the product out within two years (24 months); what is the probability of that occurring? If the product can be brought to market within 6 months of the first mover window, management assumes the project is still worth pursuing; what is this probability? If the project takes more than 30 months to develop, it is assumed the market will be saturated and it is almost a certainty the product will be a failure; what is the likelihood of this scenario
