Earned Value (EV): The physical work accomplished plus the authorized budget for this work. The sum of the approved cost estimates (may include overhead allocation) for activities (or portions of activities) completed during a given period (usually project-to-date). Previously called the budgeted cost of work performed (BCWP) for an activity or group of activities. (来源：英语学习门户 http://www.EnglishCN.com)

Earned Value Management (EVM): A method for integrating scope, schedule, and resources, and for measuring project performance. It compares the amount of work that was planned with what was actually earned with what was actually spent to determine if cost and schedule performance are as planned.

Effort: The number of labor units required to complete an activity, or other project element. Usually expressed as staff hours, staff days, or staff weeks. Should not be confused with duration.

Element: One of the parts, substances, or principles that make up a compound or complex whole.

Estimate: An assessment of the likely quantitative result. Usually applied to project costs and durations and should always include some indication of accuracy (e.g., +x per­cent). Usually used with a modifier (e.g., preliminary, conceptual, feasibility). Some application areas have specific modifiers that imply particular accuracy ranges (e.g., order-of-magnitude estimate, budget estimate, and definitive estimate in engineering and construction projects).

Estimate at Completion (EAC): The expected total cost of an  activity, a group of activities, or the project when the defined scope of work has been completed. Most techniques for forecasting EAC include some adjustment of the original cost estimate, based on actual project performance to date.

Estimate to Complete (ETC): The expected additional cost needed to complete an activity, a group of activities, or the project. Most techniques for forecasting ETC include some adjustment to the original estimate, based on project performance to date. Also called estimated to complete." See also earned value and estimate at completion.

Event-on-Node: A network diagramming technique in which events are represented by boxes (or nodes) connected by arrow to show the sequence in which the events are to occur Used in the original program evaluation and review technique.

Exception Report: Document that includes only major variations from plan (rather than all variations).

F

Fast Tracking: Compressing the project schedule by overlapping activities that would normally be done in sequence, such as design and construction.

Finish Date: A point in time associated with an activity’s completion. Usually qualified by one of the following actual, planned, estimated, scheduled, early, late, baseline, target, or current.

Finish-to-Finish (FF): See logical relationship.

Finish-to-Start (FS): See logical relationship.

Firm Fixed-Price (FFP) Contract: A type of contract where the buyer pays the seller a set amount (as defined by the contract), regardless of the seller's costs.

Fixed-Price Contract. See firm fixed-price contract.

Fixed-Price-Incentive-Fee (FPIF) Contract: A type of contract where the buyer pays the seller a set amount (as defined by the contract), and the seller can earn an additional amount if it meets defined performance criteria

Float: The amount of time that an activity may be delayed from its early start without delaying the project finish date. Float is a mathematical calculation, and can change as the project progresses and changes are made to the project plan. Also called slack, total float, and path float. See also free float.  

Forecast Final Cost: See estimate at completion.

Forward Pass: The calculation of the early start and early finish dates for the uncompleted portions of all network activities See also network analysis and backward pass.

Fragnet: See subnet.

Free Float (FF): The amount of time that an activity can be delayed without delaying the early start of any immediately following activities See float.

Functional Manager: A manager responsible for activity in a specialized department or function (e.g., engineering, manufacturing, marketing).

Functional organization: An organization structure in which staff are grouped hierarchically by specialty (e.g., production, marketing, engineering, and accounting at the top level; with engineering, further divided into mechanical, electrical, and others).

G

Gantt Chart. See bar chart.

Grade: A category or rank used to distinguish items that have the same functional use (e.g., "hammer"), but do not share the same requirements for quality (e.g., different hammers may need to withstand different amounts of force).

Graphical Evaluation and Review Technique (GERT): A network analysis technique that allows for conditional and probabilistic treatment logical relationship (i.e., some activities may not be performed).
