Question 1

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 used to optimize the network sequence by rearranging project subtasks to make the overall network more efficient.

Question 2

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 based on the standard three-point estimation technique, where the most pessimistic estimate is determined by considering the worst-case scenario and assigning a value that has a 99% probability of completion within that time.

Question 3

What is the underlying theory to the three time estimates approach? What data distribution should be applied in this case and what confidence should a project manager place in the calculations associated with this technique?

Accepted Answer

The answer of What is the underlying theory to the...

Question 4

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, as it is based on the deviation of each data point from the mean. However, knowing the mean can help provide context and interpretation for the standard deviation.

Question 5

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 10

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.
