Question

1. State whether each of the following statement is true or false. a) The sequence of activities in a project is depicted by the precedence (0.5 mark) (0.5 mark) relationships. The critical path is the shortest path through the project network. Slack is the amount of time an activity can be delayed without delaying the project. In PERT, three time estimates (optimistic, most likely and pessimistic) provide an estimate of the mean and variance for each activity based on the normal distribution. The critical path activities have no slack. b) c) (0.5 mark) d) (0.5 mark) (0.5 mark) e) f In PERT, the project variance is the sum of the variance of all project g) h) activities. In PERT, the path with the fewest activities is referred to as the critical path. When earliest finish is subtracted from latest finish, we obtain the slack value (0.5 mark) (0.5 mark)
