Project management requires:
Scheduling, planning, and controlling.
Quantitative skills
Behavioral skills
All of the following statements is true about a critical path.
A critical path consists of activities for which early start time equals late start time.
The activities along the critical path take the longest time.
A critical path consists of activities for which early finish time equals late finish time.
There is no slack in the activities along the critical path.
Which of the following statements is incorrect about the PERT method of project scheduling?
PERT assumes that the statistical variation in total project completion times can be computed by multiplying variances along the critical path.
All of the following statements are correct about the PERT method of project scheduling.
PERT requires three time estimates for scheduling a given activity.
PERT assumes that the actual activity times are distributed according to the beta probability distribution.
The standard deviation of the project is square root of the variance of the critical path.
CPM network scheduling assumes a second order (non-linear) time-cost tradeoff exists.
False
Multiple critical paths can exist under CPM because
Different network paths exist, each with the same total time
PERT assumes that the statistical variation in total project completion times can be computed by adding the standard deviations along the critical path.
False
The advantage(s) of the network method over the Gantt chart is (are) that:
The network method shows precedence relationships explicitly when compared to Gantt charts.
A forward pass is required while computing the early start and early finish times of activities.
True
“Slack” refers to the difference between:
Late and early times
Which of the following statements about CPM is true?
The CPM method is well suited when activity times are fairly constant and can be reduced by spending more money.
