Note the six distinct path times and variances for a project PERT chart (individual activity times not shown): Path # Expected completion time (days) Variance (days) 1 20 3.5 2 18 2.8 3 25 3.4 4 12 2.2 5 17 3.1 6 10 1.9 What is the probability of completing the project within 30 days (TC)? Z=(TC - Tey/Project Std Deviation, where TC = client desired completion time: Te=expected project completion time, Project standard deviation Sq. root of the Project Variance (critical path variance) 0.6577 0.9838 0.9034 0.8752 Given the following activity network: A2 A1 Activity A1 takes 5 weeks, A2 takes 8 weeks, and A3 takes 2 weeks. What is the latest completion time of A3? Every task has to be done in order to complete the project. (Hint: Remember LCtime is the latest time by which you will have to complete that task - even though you may sometimes have a choice of doing it earlier) 7 weeks 13 weeks 10 weeks 15 weeks Given the following activity network: A2 A1 A3 Activity A1 takes 5 weeks, A2 takes 8 weeks, and A3 takes 2 weeks. What is the latest start time of A3? All activities must be done in order to complete the project. (Hint: find out the latest completion time for A3, consider how long it takes to do, and then compute it's latest start time) 5 weeks 11 weeks 13 weeks 7 weeks
