A well-worded objective will be Specific, Measurable, Attainable/Achievable, Realistic and Time bound (SMART). [D05031]

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]

A specific, time-limited and preferably quantifiable outcome sought to successfully achieve goals. [D06462]

Objective Probability

Objective Quality Evidence

These characteristics are identified in drawings, specifications, and other documents which describe the item, process, or procedure.) [D01099]

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

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]

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.
Editor's Note: The Operation Phase is part of the product life cycle as distinct from the project life cycle. [D04465]

Operational Acceptance
The official act of transferring responsibility for system operation to the final user. [D04161]

Operational and Maintenance Acceptance
Acceptance by the person or group who will support the product during its useful life that it is accepted into the operational environment. The format of the acceptance will depend on the product itself - it could be in the form of an acceptance letter signed by the appropriate authority, or a more complex report detailing the operational and maintenance arrangements that have been put in place.
