Terminology
Critical path
The longest path through the activity network that allows for the completion of all project-related activities
-
-
Burst activity
an activity that has more than one activity immediately following it (more than one dependency arrow flowing from it)
Merge activity
an activity that has two or more preceding activities on which it depends (more than one dependency arrow flowing into it)
Parallel activity
Activities that can occur independently and, if desired, not at the same time
-
Free slack
Is how long an activity can exceed its early finish date without affecting early start dates of any successor(s).
Only activities that occur at the end of a chain of activities, where you have a merge activity, can have free slack.
-
Is the amount of time an activity can be delayed after the start of a longer parallel activity or activities.
Hammock activity
-
Is used to aggregate sections of the project to facilitate getting the right level of detail for specific sections of a project.
-
-
Total slack
-
-
Is how long an activity can exceed its early finish date without affecting the project end date or an imposed completion date.
-
-
Sensitivity
-
A network schedule that has only one critical path and noncritical activities that enjoy significant slack would be labeled ‘insensitive’.
Concurrent engineering
Cross-functional teamwork in new-product development projects that provides product design, quality engineering, and manufacturing process engineering all at the same time.
