QUEST Management has decided to "crash" a project in order to avoid penalty payments for late deliveries. To crash the project, either overtime or additional resources should be assigned to:
A All activities.
B Only those activities with the longest time durations.
C Those activities on the critical path begining with the longest time duration activities.
D Those activities with the greatest degree of risk.
E None of the above.
C
QUEST A network has been developed with resources from six different departments. One of the six departments has just informed you that they can increase the number of employees from 5 to 8. This will result in:
A A shortening of the critical path.
B A shortening of the noncritical path.
C A decrease in the total cost of the project.
D An increase in the cost of the project.
E A through D are possible based upon where the resources are deployed.
E
QUEST Bar charts are most appropriate for:
A Comparing actual to planned performance to each activity.
B Showing slack time.
C Showing critical path dependencies.
D Showing which activities can be rearranged in parallel.
E All of the above.
A
QUEST A non-critical path activity is completed in half the time. Then,

B The slack in the path containing this activity will increase.
C The total cost for this activity has decreased.
D Manpower from this activity can be assigned to other activities.
E All of the above.
B
QUEST Once the logic of a network is laid out, the project manager will conduct a forward pass and backward pass through the network. This will provide information on the _____ and identification of the _____ .
A Slack for each activity, critical path.
B Slack for each activity, high risk activities.
C Manpower shortages, high risk activities.
D High risk activities, non-critical paths.
E Manpower availability, contingency plans.
A
QUEST ADM is an activity-on-arrow method. In this method, a dummy activity:

QUEST The critical path in a network is the path that:
A Has the greatest degree of risk.
B Will elongate the project if the activities on this path take longer than anticipated.
C Must be completed before all other paths.
D All of the above.
E A and B only.
B
QUEST The major difference between PERT and CPM networks is:
A PERT requires three time estimates whereas CPM requires one time estimate.
B PERT is used for construction projects whereas CPM is used for R & D.
C PERT addresses only time whereas CPM also includes cost and resource availability.
D PERT requires computer solutions whereas CPM is a manual technique.
E PERT is measured in days whereas CPM uses weeks or months.
