question
Activity-on-arrow (AOA)
answer
Activity-on-arrow method for drawing project networks. The activity is shown as an arrow.

question
Concurrent engineering
answer
Crossfunctional teamwork in new-product development projects that provides product design, quality engineering, and manufacturing process engineering all at the same time.
question
Critical path
answer
The longest activity path(s) through the network. The critical path can be distinguished by identifying the collection of activities that all have the same minimum slack.
question
Gantt chart
answer
A graphic presentation of project activities depicted as a time-scaled bar line.
question
Hammock activity
answer
A special-purpose, aggregate activity that identifies the use of fixed resources or costs over a segment of the project—e.g., a consultant. Derives its duration from the time span between other activities.
question
Lag relationship
answer
The relationship between the start and/ or finish of a project activity and the start and/or finish of another activity. The most common lag relationships are (1) finish-to-start, (2) finish-to-finish, (3) start-tostart, and (4) start-to-finish.
question
Merge activity
answer
An activity that has more than one activity immediately preceding it.
question
Parallel activity
answer
One or more activities that can be carried on concurrently or simultaneously.
question
Sensitivity
answer
The likelihood that the critical path(s) will change once the project begins to be implemented.
