APMP Section 5b
| Term | Definition |
|---|---|
| Baseline | The reference levels against which a project, programme or portfolio is monitored and controlled. |
| Planning | Determines what is to be delivered, how much it will cost, when it will be delivered, how it will be delivered and who will carry it out. |
| Roll out | The process of delivering a number of nearly identical products to a number of users, usually after the product has been tested and shown to meet requirements. |
| Subproject | A group of activities represented as a single activity in a higher level of the same project. |
| Actual progress | A measure of the work that has been completed for comparison with the baseline. |
| Control | Tracking performance against agreed plans and taking the corrective action required to meet defined objectives. |
| Cyberbetic control | The form of control that deals with routine progress tracking and corrective action using a feedback loop. |
| Earned value | The value of completed work expressed in terms of the budget assigned to that work. |
| Earned value management | A project control process based on a structured approach to planning, cost collection and performance measurement. |
| Milestone | A key event selected for its importance in the schedule. |
| S-curve | A graphic display of cumulative costs, labour hours or other quantities, plotted against time. |
| Slip chart | A pictorial representation of the predicted completion dates of milestones or activities compared to their planned completion dates. |
| Three-point estimate | An estimate in which the most likely mid-range value, an optimistic value and a pessimistic, worst case value are given. |
| Top down cost estimating | An estimating approach based on historical costs and other project variable. |
| Program evaluation and review technique (PERT) | A network analysis technique that calculates standard deviations for the schedule based on three-point estimates of activity durations. |
| Bottom-up estimating | An estimating technique that uses detailed specifications to estimate time and cost for each product or activity. |
| Comparative estimating | An estimating technique based on the comparison with, and factoring from, the costs of similar, previous work. |
| Delphi technique | A process where a consensus view is reached by consultation with experts. |
| Estimate | An approximation of project time and cost targets, refined throughout the project life cycle. |
| Estimating | The use of a range of tools and techniques to produce estimates. |
| Parametric estimating | An estimating technique that uses a statistical relationship between historic data and other variables to calculate an estimate. |
| Project management plan (PMP) | A plan that brings together all the plans for a project. |
