Late start date

In the critical path method, the latest possible point in time when the uncompleted portions of a schedule activity can start based on the schedule network logic, the project completion date, and any schedule constraints



Network logic

The collection of schedule activity dependencies that makes up a project network diagram



Total float

The amount of time that a schedule activity can be delayed or extended from its early start date without delaying the project finish date or violating a schedule constraint



Work period

A distinct, scheduled portion work performed during the course of a project



Free float

The amount of time that a schedule activity can be delayed without delaying the early start date of any successor or violating schedule constraint



Actual duration

The time in calendar units between the actual start date of the schedule activity and either the data date of the project schedule if the schedule activity is in progress or the actual finish date if the schedule activity is complete



Project schedule network diagram

A graphical representation of the logical relationships among the project schedule activities



Subnetwork

A subdivision (fragment) of a project schedule network diagram, usually representing a subproject or a work package that is often used to illustrate or study some potential or proposed schedule condition such as changes in preferential schedule logic or project scope

variance (SV) and schedule performance index (SPI), are used to assess the magnitude of variation to the
original schedule baseline.

Trend analysis

An analytical technique that uses mathematical models to forecast future outcomes based on historical results. It is a variance from baseline of a budget, cost, schedule, or scope parameter by using prior progress reporting periods' data and projecting how much that parameter's variance from baseline might be at some future point in the project if no changes are made in executing the project
