| Baseline budget | The plan-budgeted value of the work scheduled.
|
 |
|
|
| Control chart | A chart that plots the difference between scheduled time on the critical path at the report date with the actual point on the critical path.
|
|
|
|
| Cost performance index (CPI) | The ratio of budgeted costs to actual costs (BCWP/ACWP).
|
|
|
|
| Cost variance (CV) | The difference between EV and AC (CV = EV – AC). Tells if the work accomplished cost more or less than was planned at any point over the life of the project.
|
|
|
|
| Earned value (EV) | The physical work accomplished plus the authorized budget for this work. Previously this was called the budgeted cost of work performed (BCWP).
|
|
|
|
| Estimated cost at completion (EAC) | The sum of actual costs to date plus revised estimated costs for the work remaining in the WBS. The text uses EACre to represent revisions made by experts and practitioners associated with the project.
|
|
|
|
| Percent complete index | Indexes that compare the to-date progress to the end of the project. The implications underlying use of these indexes are that conditions will not change, no improvement or action will be taken, and the information in the database is accurate.
|
|
|
|
| Schedule performance index | The ratio of work performed to work scheduled (EV/PV).
|
|
|
|
| Schedule variance (SV) | The difference between the planned dollar value of the work actually completed and the value of the work scheduled to be completed at a given point in time (SV = EV – PV). Schedule variance contains no critical path information.
|
|
|
|
| Scope creep | The tendency for the scope of a project to expand once it has started.
|
|
|
|
| To complete performance index (TCPI) | An index that is useful as a supplement to the estimate at complete (EACf) computation. This ratio measures the amount of value each remaining dollar must earn to stay within the budget.
|
|
|
|
| Tracking Gantt chart | A Gantt chart that compares planned versus actual schedule information.
|
|
|
|
| Variance at completion (VAC) | Indicates expected actual cost over- or underrun at completion (VAC = BAC - EAC).
