Lag time
The amount of time delay between the completion of one task and the start of its successor task. For example, if you need a 2-day delay between the finish of one task and the start of another, you can establish a finish-to-start dependency and specify a 2-day lag time. You enter lag time as a positive value.
Lead time
An overlap between tasks that have a dependency. For example, if a task can start when its predecessor is half finished, you can specify a finish-to-start dependency with a lead time of 50 percent for the successor task. You enter lead time as a negative value.
Legend
An explanatory list of symbols that is or can be on a printed chart or graph.
Leveling
Resolving resource conflicts or overallocations by either delaying certain tasks and assignments or by splitting tasks.
Link
A dependency between tasks that specifies when a task begins or ends relative to another task.
Link line
On the Gantt bar chart and the PERT chart, the line that appears between two tasks to indicate a task dependency.
Linking
In a project, establishing a dependency between tasks. When you link tasks, you define a dependency between their start and finish dates. There are four kinds of task dependencies: finish-to-start (FS), start-to- start (SS), finish-to-finish (FF), and start-to-finish (SF).
In object linking and embedding (OLE), establishing a connection between programs, so that information such as a chart or text in a container document can be updated whenever that information changes in the source document. See embedding.
