Deck 5: Scheduling the Project

Question 1

Technical dependencies are often harder to see on a Gantt chart than on a PERT/CPM network.

Answer 1

True

Question 2

To manage a project successfully,the project manager need only pay close attention to tasks on the critical path.

Answer 2

False

Question 3

"Merger" is a term used to describe the situation in which two or more paths in a network join together.

Answer 3

True

Question 4

AON and AOA networks can both be used to depict any project network.

Question 5

A disadvantage of Gantt charts is that they are hard to draw.

Question 6

Milestones cannot be identified on a Gantt Chart.

Question 7

The difference between EST and LFT is called slack.

Question 8

The difference between LST and LFT is called slack.

Question 9

If task duration estimates are carefully made,the project manager needs to only examine the critical path when conducting a risk analysis.

Question 10

A Gantt chart can NOT depict a critical path,only a PERT/CPM chart can.

Question 11

Standard Pert/CPM networks can be use to resolve probabilistic concerns

Question 12

Critical path tasks always have zero slack.

Question 13

A start-to-finish linkage is the most common way of linking to successive task.

Question 14

The actual project duration will be known with certainty after the project is completed.

Question 15

The formula for the expected time of an activity in a network assumes that the optimistic,pessimistic,and most likely time estimates have a Beta distribution.

Question 16

A project schedule is a project action plan converted into a timetable.

Question 17

When it was originally developed,PERT used certain (deterministic)methods to estimate activity duration.

Question 18

It is easiest to see lead and lag time in a project task on a PERT/CPM networks.

Question 19

The difference between the LST and EST is called slack.

Question 20

The shortest time to complete a network is equal to the duration of the longest path through the network.

Question 21

The tasks of project planning,project budgeting,and project scheduling are largely separable from one another.

Question 22

An event is a series of connected activities.

Question 23

For which purpose is simulation NOT used with regard to project scheduling?

A) to overcome the limitations associated with statistical techniques used to develop probability of completion time estimates
B) to investigate the range of project completion times
C) to investigate the distribution of project completion times
D) to verify the accuracy of the optimistic, pessimistic and most likely time estimates
E) all of the above

Question 24

A disadvantage of using beta distribution to approximate activity times is that it is generally less flexible than the normal distribution.

Question 25

What is project slack?

A) The amount of time a non-critical task can be delayed without making the project late.
B) The amount of time the critical path of a project can be delayed without making the project late.
C) The amount of time an activity on the critical path can be delayed without making the project late.
D) The difference between how long the project would take if all tasks were completed based on their pessimistic versus optimistic time estimates.
E) None of the above.

Question 26

PERT was originally used for what type of project?

A) construction
B) R & D
C) military
D) computer software development
E) advertising

Question 27

Which of the following is typically used as the best estimate of task duration?

A) expected time
B) pessimistic time
C) optimistic time
D) most likely time
E) none of the above

Question 28

A big advantage of AON networks is that they are easier to draw.

Question 29

The start-to-finish linkage is used in situations where is it desirable for two or more activities to finish at the same time.

Question 30

What is the expected time to complete a task with an optimistic,most likely,and pessimistic times of 3,4,and 7 days respectively?

A) 3
B) 4
C) 4.3
D) 4.7
E) 7

Question 31

Another name for total slack is free slack.

Question 32

What is the standard deviation of a task with optimistic,most likely,and pessimistic times of 3,4,and 7 days respectively assuming the estimates were made at the 99% plus level?

A) )444
B) )667
C) 1.212
D) 1.469
E) 1.540

Question 33

Technical dependencies on a project plan are easiest to see on a:

A) Gantt chart
B) Cost chart
C) PERT/CPM chart
D) Work Breakdown Structure
E) RACI Matrix

Question 34

The simulation approach is generally preferred over the statistical method.

Question 35

Which of the following is NOT an element of the Gantt chart?

A) actual progress
B) variance of the critical path
C) the current date
D) scheduled milestones
E) all of the above are elements

Question 36

The difference between LFT and EFT is called slack.

Question 37

Which of the following terms is most closely associated with a task required by the project?

A) activity
B) event
C) milestone
D) network
E) path

Question 38

What is it a milestone?

A) a significant event in the project
B) a mark on a chart that depicts project progress
C) an activity on the critical path
D) an activity with an uncertain completion time
E) all of the above

Question 39

Technical dependencies are generally easier to see on a Gantt chart than on PERT/CPM networks.

Question 40

.Milestones are not depended upon the predecessor activities in the project plan.

Question 41

An identifiable state resulting from the completion of one or more activities is called?

A) an event
B) an activity
C) a milestone
D) a path
E) the critical path

Question 42

A Term NOT used in the discussion of PERT/CPM analysis is

A) Activity
B) Events
C) Critical Path
D) Sensitivity path
E) network s

Question 43

The amount of time a noncritical task can be delayed without delaying the project is called?

A) surplus
B) flop
C) slack
D) critical time
E) safety

Question 44

Slack is calculated as?

A) LFT - EST
B) LFT - LST
C) LST - LFT
D) LFT - EFT
E) EFT - EST

Question 45

What is a merger and what problems do mergers create?

Question 46

Which of the following linkages is used to start two or more activities at the same time?

A) finish-to-start
B) start-to-start
C) finish-to-finish
D) start-to-finish
E) They can all be used to start two or more activities at the same time.
