Question 1

Preceding activities are those that must occur before others can be done.

Accepted Answer

Preceding activities are those that are necessary to be completed before other activities can begin. Therefore, they must occur earlier in the project timeline.

Question 2

Laddering is a technique that allows the project manager to redraw the network to more closely sequence project subtasks to make the overall network sequence more efficient.

Accepted Answer

Laddering is a technique that allows the project manager to redraw the network to more closely sequence project subtasks to make the overall network sequence more efficient.

Question 3

The late finish times are determined by taking a(n)________ through the network.

Accepted Answer

backward pass

Question 4

A(n)________ is a point when an activity is either started or completed.

Accepted Answer

The answer of A(n)________ is a point when an activity...

Question 5

A backward pass is performed when it is necessary to undo some work that has been performed in order to complete it properly.

Accepted Answer

A backward pass in project management refers to the process of calculating the latest start and finish times for project activities, to determine the project's latest completion date without delaying the project, not undoing work.

Question 6

The amount of time that an activity may be delayed from its early start without delaying the entire project is ________.

Accepted Answer

The answer of The amount of time that an activity...

Question 7

Burst activities are those with two or more successor activities.

Accepted Answer

Burst activities are those with two or more successor activities, but the term specifically used to describe this in project management is not "burst activities" but rather "split activities" or nodes where the path diverges into two or more paths. Burst activities might be confused with the term, but it's not a standard term for this concept.

Question 8

A(n)________ is a project schedule whose start and finish dates reflect expected resource availability.

Accepted Answer

The answer of A(n)________ is a project schedule whose start...

Question 9

Float is always measured in exactly the same way as slack.

Accepted Answer

The answer of Float is always measured in exactly the...

Question 10

________ is the identification of the project objectives and the ordered activity necessary to complete the project.

Accepted Answer

The answer of ________ is the identification of the project...

Question 11

At a burst point in a backward pass,the largest succeeding late start becomes the late finish for that node.

Accepted Answer

The answer of At a burst point in a backward...

Question 12

In assigning a value for the most pessimistic (b)duration,the project manager should estimate the duration of the activity to have a 99% likelihood that it will take b or less amount of time.

Accepted Answer

This statement is true according to the three-point estimation technique used in project management. The most pessimistic duration is determined by estimating the activity duration with a 99% likelihood that it will be completed within that duration or less.

Question 13

Negative float exists when a project's critical path has been completed more quickly than anticipated.

Accepted Answer

The answer of Negative float exists when a project's critical...

Question 14

Hammock activities break a task into greater levels of detail so that each task is represented as two or more subtasks that each have their own duration and precedence requirements.

Accepted Answer

A hammock activity is a schedule or project management term for a grouping or summary of subtasks that hangs between two dates. It is not about breaking a task into greater detail but rather about summarizing or aggregating subtasks to reflect a broader scope or time span within the project.

Question 15

Activity float is the difference between the late finish and early finish for the activity in question.

Accepted Answer

Activity float is calculated by subtracting the Early Finish (EF) from the Late Finish (LF) of an activity. Therefore, the statement is true.

Question 16

A merge activity has two or more immediate predecessors.

Accepted Answer

A merge activity is a type of activity that has two or more immediate predecessors. It is used when multiple concurrent activities must be completed before a single activity can proceed. The merge activity waits until all its predecessors are completed before it can start.

Question 17

The PERT technique assumes that durations are more deterministic.

Accepted Answer

The PERT (Program Evaluation and Review Technique) technique assumes that durations are probabilistic rather than deterministic, meaning that there is a range of possible durations for each activity, rather than a single fixed duration. PERT uses three time estimates for each activity: optimistic, most likely, and pessimistic, and calculates a weighted average to estimate the expected duration.

Question 18

The late start time should be calculated using a forward pass through the network.

Accepted Answer

The late start time is calculated using a backward pass through the network, starting from the project's end date and moving towards the start date.

Question 19

At a merge point in a forward pass,the largest preceding early finish becomes the early start for that node.

Accepted Answer

This statement is true. At a merge point in a forward pass, the largest preceding early finish time is used as the early start time for that node. This is because the merge point represents the point where all preceding activities must be completed before the current activity can begin.

Question 20

You must know the mean of an activity in order to determine its standard deviation.

Accepted Answer

The standard deviation can be calculated without knowing the mean, as it only requires knowing the individual data points and their deviation from the mean. However, knowing the mean can be helpful in understanding the context of the standard deviation.
