See Operations and Maintenance

See Quality Assurance Representative

An entity with a well-defined boundary and identity that encapsulates state and behavior. State is represented by attributes and relationships, behavior is represented by operations, methods, and state machines. An object is an instance of a class. See class, instance. [D04860]

A concrete statement describing what the project is trying to achieve. The objective should be written at a low level, so that it can be evaluated at the conclusion of a project to see whether it was achieved or not. A well-worded objective will be Specific, Measurable, Attainable/Achievable, Realistic and Time bound (SMART). [D05031]

Something one wants to get done. A specific statement of quality, quantity and time values. [D01096]

 TML 220
In Contract/Procurement Management, to define the method to follow and the service to be contracted or resource to be procured for the performance of work. [D01097]

In Time Management, a predetermined result, toward which effort is directed. [D01098]

The quantifiable criteria that must be met for the project to be considered successful. Objectives must included, at least, cost, schedule, and quality measures. Unquantified objectives (for example "customer satisfaction") increase the risk that the project won't meet them. [D05032]

Objective Quality Evidence
Any statement of fact, either quantitative or qualitative, pertaining to the quality of a product or service based on observations, measurements, or tests which can be verified. (Evidence will be expressed in terms of specific quality requirements or characteristics. These characteristics are identified in drawings, specifications, and other documents which describe the item, process, or procedure.) [D01099]

Predetermined results toward which effort is directed. [D01100]

Object-Oriented Analysis
Analysis based on considering the system as a collection of objects (entities, relationships, and attributes). [D04158]

A duty to make a future payment of money. The duty is incurred as soon as an order is placed, or a contract is awarded for the delivery of goods and/or the performance of services. The placement of an order is sufficient. An Obligation legally encumbers a specified sum of money which will require outlay(s) or expenditures in the future. [D03660]

Includes all anticipated expenditures which reporting personnel believe that the authority is obliged to pay, i.e. "cannot get out of". [D01101]

See Organizational Breakdown Structure

The recognizing, noting and recording of facts or occurrences, often involving measuring with instruments. [D03039]

Observation Units
  1. A group of people set up for purposes of recognizing, noting and recording facts or occurrences, often involving measurement with instruments, or
  2. The units of measurement used in making observations.

No longer current. [D04159]

OC Curves
See Operating Characteristic Curves

See Other Direct Costs

Off the Shelf Item
An item produced and placed in stock by a contractor, or stocked by a distributor, before receiving orders or contracts for its sale. [D03537]

A response to a solicitation that, if accepted, would bind the offeror to perform the resultant contract. A response to an invitation for bids or a request for proposals is an offer. A response to a request for quotations is a quote not an offer. [D03538]

A response to a solicitation or invitation to bid that, if accepted, would bind the offeror to perform the resulting contract. [D03661]

A contractor who submits a proposal in response to a solicitation package. [D05194]

See Resource Offset. [D01102]

Offsite Fabrication
The assembly of materials, components, systems and parts away from the site of the project. For example, the parts of fixed furnishings for a building may be pre-assembled in a manufacturing plant. [D03040]

See On-the-job Training

One Hundred Percent Inspection
Inspection in which specified characteristics of each unit of product are examined or tested to determine conformance with requirements. [D01104]

One on One
A direct encounter or meeting between one person and another. [D03041]

On-site Assembly
The assembly of materials, components, systems and parts on the site rather than offsite. [D03042]

On-the-job Training ("OJT")
Training by acquiring direct experience in the job environment. Usually implemented by a team or mentor approach. [D04160]

Open Projects
Projects that are not yet completed, or are completed but the project's accounts remain open for the acceptance of outstanding or late disbursements. [D03043]

Performing a function to produce an appropriate effect. [D03044]

Operating Characteristic Curves ("OC Curves")
The curve of a sampling plan which shows the percentage of lots or batches which may be expected to be accepted under the specified sampling plan for a given process quality. [D01105]

 MIL-STD 105
Operating Manuals
Books of technical instructions that describe the appropriate procedures for using and maintaining the corresponding systems or equipment. [D03045]

Operating System
A system that performs a particular function. [D03046]

Operating System, Computer
The software programming that provides the platform interface for running application software programs. [D03098]

The operation of a new facility is described by a variety of terms, each depicting an event in its early operating life. For example:
  1. Initial operation: the project milestone date on which material is first introduced into the system for the purpose of producing products.
  2. Normal operation: the project milestone date on which the facility has demonstrated the capability of sustained operations at design conditions and the facility is accepted by the client.

A service that can be requested from an object to effect behavior. An operation has a signature, which may restrict the actual parameters that are possible. [D04861]

Operation Phase
Period when the completed deliverable is used and maintained in service for its intended purpose.
