Project Management - Chapter 12: NETWORK SCHEDULING TECHNIQUES
You have an activity where the early start is week 6, the early finish is week 10, the latest start is week 14, and the latest finish is week 18. The slack in the activity is:
8 weeks
Which of the following schedule compression techniques is often the lowest risk and with the added benefit of lowering the cost? A. Crashing B. Descoping C. Outsourcing D. Overtime
B. Descoping
If an activity on the critical path takes longer than anticipated, then;
Activities not on the critical path have additional slack
If the optimistic time for an activity is 6 weeks, the pessimistic time is 24 weeks and the most likely time is 12 weeks, then the expected duration is:
13 weeks
If the slack in a 12 12-week activity is 6 weeks and ES = 4, then LF = _____.
22
An activity in a network has the following characteristics: ES = 10, EF = 18, and LS = 12. The duration of the activity is:
8
An activity in a network has the following characteristics: ES = 5, EF = 9, and LF = 12. LS = _____.
8
The shortest time necessary to complete all of the activities in a network is called the:
Critical Path
Which of the following network diagramming methods do not use dummy activities? A. PERT B. GERT C. ADM D. PDM
D. PDM
Which of the following scheduling techniques is most appropriate today for managing a project? A. BAR charts B. Milestone charts C. PERT charts D. Precedence charts
D. Precedence charts
True or False: The critical path is the path in the network with the greatest amount of risk.
False
A PERT network reflects what type of precedence diagram?
Finish-to-start
The most common "constraint" or relationship in a precedence network is:
Finish-to-start
A network based technique that allows for branching and looping is:
GERT
What are the maximum number of inputs and outputs that can exist in a node in the precedence diagramming method?
It is unlimited
The first step in the development of a schedule is:
Listing activities
A network-based schedule has four paths, namely 7, 8, 9, & 10 weeks. If the 10 week path is compressed to 8 weeks then:
Not enough information is provided to make a determination
Optimistic, pessimistic, and most likely activity times are associated with:
PERT
Laying out a network diagram when you know before-hand the size of the available resource pool is called:
Resource allocation or resource limited planning
Smoothing out project resources from period to period is called
Resource leveling
Negative slack is the result of:
The forward pass going beyond the customer's end date and the backward pass is measured from the customer's end date
Which of the following scheduling techniques is most appropriate today for reporting project status to a customer during an interchange meeting? A. BAR charts B. Milestone charts C. PERT charts D. Precedence charts
A. BAR charts
Which of the following is not a commonly used technique for schedule compression? A. Resource reduction B. Reducing scope C. Fast-tracking activities D. Use of overtime
A. Resource reduction
Which of the following schedule compression techniques usually requires adding more resources to each work package that is being compressed? A. Overtime B. Crashing C. Outsourcing D. Descoping
B. Crashing
Which of the following network diagramming methods allows for branching and looping? A. PERT B. GERT C. ADM D.PDM
B. GERT
Which of the following activity-on-arrow network diagramming methods does not require three estimates for durations?? A. PERT B. GERT C. ADM D. PDM
C. ADM
Which of the following is not one of the three types of dependencies? A. Mandatory B. Discretionary C. Internal D. External
C. Internal
Which of the following is false concerning the critical path in a network? A. It is the longest path in the network. B. It is the shortest amount of time in which the project can be completed. C. It is the path that contains the greatest number of activities. D. It is the path where each activity has zero slack.
C. It is the path that contains the greatest number of activities.
In which of the following schedule compression techniques is the cost of rework usually the greatest? A. Overtime B. Crashing C. Performing series work in parallel D. Outsourcing
C. Performing series work in parallel
Which of the following cannot be determined after performing a forward pass and a backward pass on a network diagram? A. The critical path B. The end date of the project C. The effort in each activity D. The slack in each activity
C. The effort in each activity
Which of the following is not one of the four network diagramming techniques? A. PERT B. GERT C. VERT D. PDM
C. VERT
Which of the following cannot be identified after preforming a forward and backward pass? A. Dummy activities B. Slack time C. Critical path activities D. How much overtime is scheduled
D. How much overtime is scheduled
Which of the following is an activity-on-node network diagramming method? A. PERT B. GERT C. ADM D. PDM
D. PDM
The major disadvantage of using a bar chart on large projects is that bar charts:
Do not show dependencies between activities
The major disadvantage of using bar charts to manage a project is that bar charts:
Do not show dependencies between activities
Activities with no time duration are called:
Dummy activities
Activities with zero time durations are called:
Dummy activities
True or False: The measurement of lag is made within an activity whereas slack is measured between activities.
False
Reducing the peaks and valleys in manpower assignments in order to obtain a relatively smooth manpower curve is called
Manpower leveling
