problem 1) You have the project with following tasks: Task A takes 40 hours and could start after project starts. Task B takes 25 hours and must happen after the project starts. Task C must happen after Task A and takes 35 hours. Task D must happen after Tasks B and C and takes 30 hours. Task E must take place after Task C and takes 10 hours. Task F takes place after Task E and takes 22 hours.

a) Draw network diagram.

b) What is the critical path and what is the length of the critical path?

c) If Task B actually takes 37 hours, what is the effect on project?

d) What tasks should be completed before task D can begin?

e) If senior management tells you to complete the project 20 hours early, what is the project float? How could you meet this requirement? Does the critical path change?
