Glossary of Project Management Terms

B

backward pass

the calculation of late finish dates and late start dates for the uncompleted portions of all network activities, determined by working backwards through the network logic from the project end date. The end date can be specified, although it is usually calculated in a forward pass.

baseline schedule

a project schedule that consists of baseline start and finish dates, which represent an estimated or expected schedule, or both. This schedule is often derived from an initial set of early, late, or scheduled finish dates. Typically, once a baseline schedule is established, it does not change over the course of a project.

baseline finish date (BF)

the calendar date when work on an activity is scheduled to end. This date is usually estimated, or it can be derived from the early, late, or scheduled finish dates. Typically, once a baseline schedule is established, it does not change over the course of the project.

baseline start date (BS)

the calendar date when work on an activity is scheduled to begin. This date is usually estimated, or it can be derived from the early, late, or scheduled start dates. Typically, once a baseline schedule is established, it does not change over the course of the project.

budget at completion (BAC)

the estimated total cost of the project when done.

budgeted cost of work performed (BCWP)

the sum of the approved cost estimates (including any overhead allocation) for activities (or portions of activities) that are completed during a given period (usually project-to-date). See also earned value.

budgeted cost of work scheduled (BCWS)

the sum of the approved cost estimates (including any overhead allocation) for activities (or portions of activities) that are scheduled to be performed during a given period (usually project-to-date). See also earned value.
