The processing times for each task are also given. a. Draw a precedence digraph to represent the tasks. Task A B C D E F G Processing Prerequisite Time Tasks? 4 hours None 5 hours None 3 hours A, B 6 hours 5 hours 8 hours 2 hours b. Find the critical path and critical time for the project by using the Backflow Algorithm. None A D C, E, F c. Use the following priority list to schedule the tasks for your employees. What is the finishing time? (B,A,E,C,D,F,G) d. Do you think the finishing time in part (c) is the fastest way to get the job done? Why? If yes, explain why.
