227QUESTThe starting point in the development of a top-down PERT/CPM chart is the _____ .227AProject specification tree.227BCustomer's deliverable list.227CCustomer's milestone dates.227DWork breakdown structure.227EListing of customer team meeting dates.227
228QUESTADM is an activity-on-arrow method. In this method, a dummy activity:228ADenotes a critical path relationship.228BDenotes any dependency relationship.228CShows slack.228DIdentifies customer deliverables dates.228EIdentifies customer team meeting dates.2

QUESTOnce 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 identification229
of the _____ .229ASlack for each activity, critical path.229BSlack for each activity, high risk activities.229CManpower shortages, high risk activities.229DHigh risk activities, non-critical paths.229EManpower availability, contingency plans.229
230QUESTA non-critical path activity is completed in half the time. Then,230AThe critical path is also reduced.230BThe slack in the path containing this activity will increase.230CThe total cost for this activity has decreased.230DManpower from this activity can be assigned to other activities.230EAll of the above.230
231QUESTBar charts are most appropriate for:231AComparing actual to planned performance to each activity.231BShowing slack time.231CShowing critical path dependencies.231DShowing which activities can be rearranged in parallel.231EAll of the above.2

QUESTA 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 8.232
This will result in:232AA shortening of the critical path.232BA shortening of the noncritical path.232CA decrease in the total cost of the project.232DAn increase in the cost of the project.232EA through D are possible based upon where the resources are deployed.232
QUESTManagement has decided to "crash" a project in order to avoid penalty payments for late
233
deliveries. To crash the project, either overtime or additional resources should be assigned to:233AAll activities.233BOnly those activities with the longest time durations.233CThose activities on the critical path begining with the longest time duration activities.233DThose activities with the greatest degree of risk.233ENone of the above.2

QUESTA line manager provides you with three estimates for his activity in your PERT network. His
estimates are 2 weeks optimistically, 4 weeks most likely, and 12 weeks pessimistically. The235
expected time which would appear on the chart would be:235A4 weeks2
