　　5 The first step in building a PERT/CPM network is to:

　　A Create a flow chart

　　B Determine the critical path

　　C Show task relationships

　　D Create a work breakdown structure

　　E None of the above.

　　ans:D

　　6 The critical path in a schedule network is the path that:

　　A Takes the longest time to complete

　　B Must be done before any other tasks

　　C Allows some flexibility in scheduling a start time.

　　D Is not affected by schedule slippage

　　E All of the above.

　　ans:A

　　7 Assume that you have a network where an activity on the critical path can be crashed by two weeks. If the activity is actually crashed by two weeks, then:

　　A The project's schedule will be reduced by 2 weeks.

　　B The available slack on the noncritical paths will increase.

　　C A new critical path may appear after the crash.

　　D All of the above.

　　E A and B only.

　　ans:C

　　8 Your team has prepared a CPM schedule for your review. You notice that one node has six inputs （including two dummy activities） and four outputs （which include one dummy activity）。 Select the correct statement from the following:

　　A This is a valid representation if the logic is correct.

　　B This is invalid because a node can have a maximum of one dummy input representation if the logic is correct.

　　C This is invalid because nodes cannot have both dummy inputs and dummy outputs.

　　D This is a invalid because the number of outputs must equal the number of inputs.

　　E This is invalid because a maximum of two inputs and two outputs are allowed using the critical path method.

　　ans:A

　　9 During project execution, the customer authorizes and funds a scope change which requires a major change in the schedule. The baseline schedule:

　　A Now becomes the new schedule, including the changes, and the original baseline is disregarded.

　　B Is still the original baseline but annotated to reflect that a change has taken place.

　　C Is amended to reflect the scope change, but the original baseline is still maintained for post-project review.

　　D Is meaningless since every schedule update changes the baseline （i.e., a rubber baseline.）

　　E Is the same since baseline schedules cannot change once the development phase is completed.

　　ans:C

　　10 Network schedules are prepared during the _____ phase and updated during the _____ phase.

　　A Conceptual, execution.

　　B Development, implementation.

　　C Development, close-out.

　　D Implementation, close-out.

　　E Planning, finishing.

　　ans:B

　　11 Scheduling systems such as PERT, ADM, and PDM are project management tools to be used by:

　　A The project manager and project office personnel.

　　B The project team and functional managers.

　　C The project sponsor.

　　D All of the above.

　　E A and B only.

　　ans:E

　　12 Increasing resources on the critical path activities may not always shorten the length of the project because:

　　A Certain activities are time-dependent rather than resource-dependent （i.e., using three ovens rather than one to bake a cake）。

　　B Safety, OSHA and EPA may have placed restrictions on the number of people used on certain activities or in the physical location of the project.

　　C The skill level of the added resources might not be appropriate for the activities to be performed.

　　D Adding more resources may create additional work and produce inefficiencies （i.e., additional people may need training and supervision.）

　　E All of the above.

　　ans:E

　　13 A 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. The expected time which would appear on the chart would be:

　　A 4 weeks

　　B 5 weeks

　　C 6 weeks

　　D 7 weeks

　　E None of the above.

　　ans:B

　　14 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.

　　ans:C

　　15 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.

　　ans:E

　　16 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.

　　ans:A

　　17 A non-critical path activity is completed in half the time. Then,

　　A The critical path is also reduced.

　　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.

　　ans:B

　　18 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.

　　ans:A

　　19 ADM is an activity-on-arrow method. In this method, a dummy activity:

　　A Denotes a critical path relationship.

　　B Denotes any dependency relationship.

　　C Shows slack.

　　D Identifies customer deliverables dates.
