Definition     Editor's Choice
Pre Award Survey
An evaluation of a prospective contractorÍs capability to perform under the terms of a proposed contract. [D01227]

Pre Bid Conference
A meeting used, generally in complex acquisitions, as a means of briefing prospective bidders and explaining complicated specifications and requirements to them as early as possible after the invitation for bids (IFB) has been issued and before the bids are opened. [D03544]

Pre Commissioning
That work which is carried out prior to commissioning in order to demonstrate that commissioning may be safely undertaken. [D04473]

Pre Planned Product Improvement
Designed-in provision for future enhancement. This may require the initial version to have excess capability to accommodate later enhancement. [D04177]

Pre Proposal Conference
A meeting hosted by the buyer contracting organization to assist prospective bidders in understanding the Request for Proposal. [D04179]

Pre Tender Estimate
See Definitive Estimate. [D02175]

When one task must be completed before another task can be started, the first task is said to have precedence over the other. [D01228]

 OTOB 73
Precedence Diagram
A notation of a network which places the activity on a single node. See also Activity Node Net. [D01229]

 CPMUSC 176-8
Project plan in the form of a structural network where the activities are denoted graphically by arrows. [D02174]

Precedence Diagram Method ("PDM")
A method of constructing a logic network using nodes to represent the activities and connecting them by lines that show dependencies. [D01230]

One of the two methods of representing project as networks, in which the activities are represented by nodes and the relationships between them by arcs.
Editor's Note: The other method, Arrow Diagram Method, is now rarely used. [D01231]

Precedence Diagram Method Arrow
A graphical symbol in PDM networks used to represent the lag describing the relationship between work activities. [D01232]

Precedence Diagramming
An activity oriented system in which activities are displayed in uniform boxes complete with activity number, start duration and finish dates. The logical relation between activity boxes is shown by logic connector lines. Lead and lag times can also be shown. The display is more effective than Arrow Diagramming and is also easier to revise, update, and program on computer. See also CPM and PERT. [D03082]

A technique used in CPM and PERT [D01233]

Precedence Diagramming Method
A network diagramming technique in which activities are represented by boxes (or nodes). Activities are linked by precedence relationships to show the sequence in which the activities are to be performed. [D01234]

Precedence Network
A multiple dependency network. An activity-on-node network in which a sequence arrow represents one of four forms of precedence relationship, depending on the positioning of the head and the tail of the sequence arrow. The relationships are:
  1. Start of activity depends on finish of preceding activity, either immediately or after a lapse of time
  2. Finish of activity depends on finish of preceding activity, either immediately or after a lapse of time
  3. Start of activity depends on start of preceding activity, either immediately or after a lapse of time
  4. Finish of activity depends on start of preceding activity, either immediately or after a lapse of time.

Precedence Notation
The means of describing project work flow. It is sometimes called Activity on Node notation. Graphically, precedence networks are represented by using descriptive boxes and connecting arrows to denote the flow of work. [D01235]

Precedence Relationship
The term used in the precedence diagramming method for a logical relationship. In current usage, however, precedence relationship, logical relationship, and dependency are widely used interchangeably regardless of the diagramming method in use. [D01236]

Preceding Event
In an activity-on-arrow network, an event at the beginning of an activity. [D04472]

An activity that must be completed (or be partially completed) before a specified activity can begin is called a predecessor. The combination of all predecessor and successor relationships among the project activities forms a network. This network can be analyzed to determine the critical path and other project scheduling implications. [D01237]

Predecessor Activity
  1. In the arrow diagramming method, the activity which enters a node.
  2. In the precedence diagramming method, the "from" activity.

Any activity that exists on a common path with the activity in question and occurs before the activity in question. [D01239]

In the precedence diagramming method it is the "from activity," or the activity which logically precedes the current activity. [D01240]

Predecessor Task
A task that must start or finish before another task can start or finish. [D01241]

Predecessor Work Item
A work item that directly precedes one or more work items in the logic sequence of a precedence network. [D01242]

Preferred Alternative
The solution, amongst several, to an opportunity, need, or problem before or after project launch that is most likely to be successful. [D03149]

Something that precedes or is introductory or preparatory. Coming before and usually forming a necessary prelude to something else. [D03150]

Preliminary Design
The design prepared in the planning stage of a project and submitted as part of the project brief. The drawings and specifications that comprise the Preliminary Design should be clearly specified as a matter of policy and provide the basis for the Appropriation estimate. [D01243]

Preliminary Design Documentation
"Design-to" specifications, verification plan, concept drawings, analyses, flow diagrams, data sheets, pictorials, schematics, etc. that convey the technical and operational requirements of the system or entity of the system. [D04178]

Preliminary Design Review
A series of control gates at which the Buyer reviews and approves the Provider's proposed Design-to baseline as evidenced by lower level performance specifications and associated test plans and authorizes the Provider to proceed with detail design. All hardware, software, handling equipment, test equipment, and tooling should be sequentially reviewed in the descending order of system to assembly. [D01244]

 VPM 291-4
Preliminary Economic Criteria
The early determination of economic conditions established as a prerequisite to the approval of a project, usually one of several alternatives. [D03151]

Preliminary Estimate
See Estimate Class B [D02223]

Preliminary Technical Criteria
The early determination of technical criteria established for purposes of project design development, often as part of a feasibility study. [D03152]

An assessment of capabilities, current capacity, etc. as an initial part of a selection process. Used to narrow the number of bidders when inviting tenders for contract work and thereby reduce the amount of work for both those bidders unlikely to be successful on these grounds as well as the amount of work in reviewing the submissions and making a final selection for award. [D03153]

To direct specified action. To prescribe implies that action must be carried out in a specified fashion. [D01245]

Laid down as a guide, direction, or rule of action; specified. Usually implies instructions that are given step by step in some detail and that are to be followed without questioning, i.e. what is to be done, rather than how it is to be done, i.e. Descriptive. [D03154]

Present Value
The calculation in current dollars of a regular stream of payments or income over a given period by adjusting for some value of annual interest or inflation. [D03155]

The relative worth of a benefit received or cost expended at a specified time in the future when the applicable discount rate is considered. [D03545]

The value now of a future payment, after discounting it by a suitable discount rate to recognize that it is worth less than a payment of the same amount made now. [D05041]

A descriptive or persuasive account, typically for purposes of obtaining approval or acceptance for some offer, position or requirement. [D03156]

Presentation Format
The manner, sequence, conditions or layout, etc. under which a presentation is to be made. [D03157]

Presentation Software
Computer software programs that may be used for creating, animating, and projecting a presentation using appropriate equipment. [D03158]

Presentation Speaking
A particular art of oral presentation that is effective and persuasive and may be learned. There are different styles and speakers generally the style most suited to their personality. [D03159]

Pressure Groups
Groups of people that are active, often politically, that have power to influence the course of a project, and do so if they are impacted by it. See also Constituents, and Public Relations. [D03160]

Pretty Good Privacy ("PGP")
A class of software that provides security of information in storage or during transmission. [D04866]

Preventive Maintenance
All actions performed in an attempt to retain an item in specified condition by providing systematic inspection, detection, and prevention of incipient failures. [D03672]

 MIL-STD 1388-1A
  1. Cost plus any fee or profit applicable to the contract type, or
  2. The amount paid for a supply or service.

The quantity of one thing that is exchanged or demanded in barter or sale for another. The amount of money given or set as consideration for the sale of a specified thing. The cost at which something is obtained. [D03162]

Price Variance ("PV")
The difference between the budgeted costs for a purchased item and the actual costs. [D04650]

The setting of, or finding out about, prices for goods, services, contract work, etc. [D03161]

The process of establishing a reasonable amount or amounts to be paid for supplies or services. [D03547]
