Question 1

The longest route through the network is the __________.

Accepted Answer

critical path

Question 2

__________ activities have two or more immediate predecessors.

Accepted Answer

Merge

Question 3

Because an activity's pessimistic estimate may represent a much greater deviation from the most likely time than its optimistic estimate, the __________ better represents the distribution of possible alternative durations.

Accepted Answer

beta distribution

Question 4

A merge activity has two or more immediate predecessors.

Accepted Answer

A merge activity combines two or more parallel paths that were previously split by a decision point. Therefore, it has two or more immediate predecessors.

Question 5

There is no slack on the project __________.

Accepted Answer

The answer of There is no slack on the project...

Question 6

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

Accepted Answer

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

Question 7

Activities that can be worked on simultaneously are __________ activities.

Accepted Answer

The answer of Activities that can be worked on simultaneously...

Question 8

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 9

__________ activities can be used as summaries for some subsets of the activities identified in the overall project network.

Accepted Answer

The answer of __________ activities can be used as summaries...

Question 10

Thanks to excessive dilly dallying, the subcontractor grossly exceeded the slack on his portion of the project, resulting in __________.

Accepted Answer

The answer of Thanks to excessive dilly dallying, the subcontractor...

Question 11

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

Accepted Answer

The answer of The late finish times are determined by...

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

The most pessimistic duration should be estimated with a high level of certainty, typically around a 99% likelihood that the activity will take that duration or less. This helps to ensure that there is adequate contingency time built into the project schedule to account for potential delays or setbacks.

Question 13

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 14

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

Accepted Answer

Standard deviation can be calculated without knowing the mean, but it does become easier to interpret when the mean is known.

Question 15

__________ 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 16

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 be started or completed.

Question 17

__________ activities have two or more immediate successors.

Accepted Answer

The answer of __________ activities have two or more immediate...

Question 18

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 19

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 20

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 real technique used in project management to resequence the network in order to make it more efficient.
