Activity-on-Arrow (AOA)
Represents the task, or activity, and the node signifies an event marker that suggests the completion of one activity and the potential to start another.
Activity-on-node (AON)
The node represents an activity, and the path arrows demonstrate the logical sequencing from node to node through the network.
Arrow
Represents the task
Backward pass
Calculation of late finish times (dates) for all uncompleted network activities
Beta distribution
Distributions that are asymmetrical
Burst activity
An activity with two or more immediate successor activities (task flowing out from it)
Concurrent
When more than one activity to be accomplished at the same time.
Confidence interval
The highest reasonable probability of being accurate.
Crashing
Speeding up the project
Critical path
The path through the project network with the longest duration. These are identified as having zero float in the project.
Critical Path Method (CPM)
A Network analysis technique used to determine the amount of scheduling flexibility.
Durations
Estimate activity for each step in the project
Early start (ES) date
Earliest possible date on which the uncompleted portions of an activity can start.
Event
A point when an activity is either started or completed
