Unavoidable Delay
A production delay the operator cannot prevent. [D03703]

All events, both positive and negative whose probabilities are neither 0% nor 100%. Uncertainty is a distinct characteristic of the project environment. [D02229]

Lack of knowledge of future events. See also Project Risk. [D02094]

The possibility that events may occur which will impact the project either favorably or unfavorably. Uncertainty gives rise to both opportunity and risk. See also (project) risk. & [D02095]

A condition, event, outcome, or circumstance for which the extent, value, or consequence is not predictable. [D03704]

A source of risk derived from a lack of sufficient knowledge about the underlying probabilities of adverse events and/or their consequences. [D05138]

Uncontrollable Risks
Those risks to the project which, if occurring, cannot be mitigated in any way by the project manager or his/her team, are listed in the project plan as excluded from the projectÍs estimated cost and schedule and require the prior direction of the projectÍs sponsor before any further action can be taken. Such action may range from the provision of additional funding to cover remedial actions, to temporary suspension, to aborting the whole project. [D02096]

Assigning a resource to work fewer hours than the resource is available. [D02097]

The amount by which an activity, piece of work or something produced falls below its corresponding estimate, usually of cost. [D03370]

Either of
  1. A mutual agreement not formally entered into but in some degree binding on each side, or
  2. A familiarity with, or comprehension of, facts and/or sympathy for situational conditions, etc.

Undistributed Budget ("UB")
Budget applicable to contract effort which has not yet been identified to specific cost accounts or work packages. [D02098]

Unified Modeling Language ("UML")
An attempt to standardize software programming using object-oriented design methods because of the steep learning curve involved. [D04890]

Uniform Resource Locator ("URL")
A standard identifier for a resource on the World Wide Web, used by Web browsers to initiate a connection. The URL includes the communications protocol to use, the name of the server, and path information identifying the objects to be retrieved on the server. [D04891]

The extent to which a project, its product, activities or any other attribute is one of a kind. [D05139]

Unit Cost
Total labor, material, and overhead cost for one unit of production, i.e., one part, one gallon, one pound, etc. [D04666]

Unit Costing
Estimating costs by measuring the amount of work, or number of units, involved and applying a standard price per unit. [D03372]

Unit of Product
The thing inspected in order to determine its classification as defective or non-defective or to count the number of defects. It may be a single article, a pair, a set, a length, an area, an operation, a volume, a component of an end product, or the end product itself. The unit of product may or may not be the same as the unit of purchase, supply, production, or shipment. [D02099]

 MIL-STD 105
Unit Price
See Unit Price Contract. [D03373]

Unit Price Contract ("UP")
A fixed price contract where the supplier agrees to furnish goods/services at unit rates and the final price is dependent on the quantities needed to carry out the work. [D02100]

See Known, Known-unknown, Unknown-unknown method. [D00889]

Revision of a schedule or network to reflect progress to date. Fully completed items are eliminated and the date of the update becomes the new reference date for the project. [D02103]

Something that calls for immediate action. [D03376]

See Uniform Resource Locator

The extent to which an item is capable of being used, or is convenient and practical in use. [D03377]

The number of units or dollars of an inventory item consumed over a period of time. [D04667]

Firmly established and generally accepted practice or procedure. The way in which words and phrases are actually used (as in a particular form or sense) in a language community by virtue of preference, convenience, or practice. [D03378]

Usage Variance
The difference between the budgeted quantity of materials and the actual quantity used. [D04668]

Use Case
A definition of the sequence of actions a system performs that yields an observable result of value to a particular actor. A use-case class contains all main, alternate flows of events related to producing the "observable result of value". [D04892]

Use-Case Model
A model that describes a system's functional requirements in terms of use cases. [D04893]

Use-Case View
An architectural view that describes how critical use cases are performed in the system, focusing mostly on architecturally significant components (objects, tasks, nodes). In the Unified Process, it is a view of the use-case model. [D04894]

A document that defines user's needs in user terminology from the user's perspective. [D04291]

An apparently intangible quality of a system interface that leads to a user's untutored response being more likely correct than not. An attribute the benefits of which include less training, faster response, fewer errors, less frustration and hence better work and cost savings. [D05140]
