Note: The start and finish of each succeeding activity are linked only to the start and finish of the preceding activity by lead and lag activities, which consume only time. [D04457]

 APM
BS
A sequence of parallel activities connected at their starts or finishes, or both. [D00892]

 WST
Ladder Activity
A type of activity identified in network scheduling. An arrangement in which two or more series of activities progress concurrently but in lockstep because of dependent links between the same rungs of each ladder. [D02924]

 RMW
Lag
The amount of time after one task is started or finished before the next task can be started or finished.
Editor's Note: A Lag may have a negative value tied to the finish of a previous activity, reflecting a Fast Track approach. [D00895]

 OTOB 271-4
A modification of a logical relationship which directs a delay in the successor task. For example, in a finish-to-start dependency with a 10 day lag, the successor activity cannot start until 10 days after the predecessor has finished. See also lead. [D00893]

 PMK96
The logical relationship between the start and/or finish of one activity and the start and/or finish of another activity. [D00894]

 PMK87
The time delay between the start or finish of an activity and the start or finish of its successor(s). See finish-to-finish lag, finish-to-start lag, and start-to-start lag. [D00898]

 WST
PMST
Either
  1. In a network diagram, the minimum necessary lapse of time between the finish of one activity and the finish of an overlapping activity, or
  2. Delay incurred between two specified activities.
[D04583]

 APM
BS
Lag Duration
A duration by which a given task must be completed before the succeeding activity can begin. [D00896]

 CPMUSC 176-8
Lag Relationship
The four basic types of lag relationships between the start and/or finish of a work item and the start and/or finish of another work item are:
  1. Finish to Start
  2. Start to Finish
  3. Finish to Finish
  4. Start to Start
[D00897]

 PMK87
Lag Time
The amount of time delay between the completion of one task and the start of its successor task. [D00899]

 MSP98
Lagging
Deliberately setting the start, or finish, of on activity behind the start, or finish, of another. A scheduling technique necessary to enable relatively concurrent progress on more than one activity. [D02925]

 RMW
LAN
See Local Area Network

  
Language
A systematic means of communicating ideas or feelings by the use of conventionalized signs, sounds, or gestures. [D00900]

 PMK87
Last In, First Out ("LIFO")
For inventory accounting purposes, the last unit into the inventory is assumed to be the first unit to be drawn out. The inventory value assigned to any unit drawn out is the value of the last unit recorded as still being in inventory. It does not matter which unit is physically drawn out of inventory. See also FIFO. [D03520]

 GAT
Late Bid
A bid received in the office designated in the invitation for bids after the exact time set for opening. [D03522]

 GAT
Late Dates
Calculated in the backward pass of time analysis, late dates are the latest dates on which an activity can start and finish. [D00901]

 WST
Late Event Date
Calculated from backward pass, it is the latest date an event can occur. [D00902]

 WST
Late Finish ("LF")
The latest time an activity may be completed without delaying the project finish date. [D00903]

 PMK87
The latest dates by which an activity can finish to avoid causing delays in the project. Many PM software packages calculate late dates with a backward pass from the end of the project to the beginning. [D00905]

 WST
PMST
Late Finish Date ("LFD")
In the critical path method, the latest possible date that an activity may be completed without delaying a specified milestone (usually the project finish date). [D00904]

 PMK96
Late Start ("LS")
The latest time an activity may begin without delaying the project finish date of the network. This date is calculated as the late finish minus the duration of the activity. [D00906]

 PMK87
The latest dates by which an activity can start to avoid causing delays in the project. Many PM software packages calculate late dates with a backward pass from the end of the project to the beginning. [D00908]

In a network diagram schedule, the latest time at which an activity can be finished. [D00910]

 SPM 304-9
Latest Finish Time
See Late Finish. [D02926]

  
Latest Start
The latest day that a work item can start without affecting the final project duration. This assumes that it is completed in its expected time and all subsequent work items start as soon as they are able and are completed in their expected times. [D00913]
