Part II-B. Based on your illustration, please answer the following.

Given the diagram above, please answer the following.

7. How many possible paths are there from the start to the end of the project?
8. Which tasks are on the critical path of the PERT chart above?
9. What is the slack time for tasks C, D and G?
10. The person working on task C tells the project manager he can't start work until one day after the scheduled starting date. What impact would this have on the completion date of the project? Why?
11. Task A will be delayed by 2 days because some equipment has arrived late. If the project manager still wants to finish the project within the original time frame, he will need to shorten the time for one or more of the tasks. What steps can he take to reduce the number of days allocated to a task?
12. The project manager decides to reduce the time needed for tasks D and F by one day each. How effective will this reduction be in achieving his aim of maintaining the original finish time for the project?
