Slack is also known as __________.

An activity or event that, if delayed, will delay project completion is called a(n)__________.

Task H has duration of 5 days, an early start of 25 days, an early finish of 30 days, a late start of 25 days, and a late finish of 30 days. There are __________ days of slack for task H.

The variance of a population is a measure of the population's __________.

The __________ chart shows planned and actual progress for a number of tasks displayed against a horizontal timescale.

__________ was developed by the U.S. Navy while the __________ was developed by __________.

The arrangement of all activities (and, in some cases, events)in a project arrayed in their logical sequence and represented by arcs and nodes is called a __________.

The authors recommend preparing a schedule for each __________.

The _________ was developed by Henry Gantt in 1917.

Describe the benefits of forming a network of activity and event relationships that graphically portrays sequential relations between tasks in a project.

Explain the difference between Total Slack and Free Slack in a network.

Assume that task J has a most likely duration of 20 days, an optimistic duration of 13 days, and a pessimistic duration of 30 days. If the optimistic and pessimistic durations are 95 percent estimates, the standard deviation for task J is ________ days.

The __________ for an activity is equal to the largest early finish for its preceding activities.

__________ have a weakness of being difficult to follow when multiple paths exist, but __________ are more helpful in the hands-on task of managing the project.

The authors define __________ as the time an activity can be delayed without affecting the start time of any successor activity

Any time two or more paths of a network come together, the probability of both paths being on time is the product of the probabilities for the individual paths. This scenario is referred to as __________.

A(n)__________ is a point where one or more lines (arrows)begin or terminate, commonly used for depicting an event or activity.

When using the beta distribution, the denominator of the formula for standard deviation should ________.
