underpinning contract (UC)

(ITIL Service Design) A contract between an IT service provider and a third party. The third party provides goods or services that support delivery of an IT service to a customer. The underpinning contract defines targets and responsibilities that are required to meet agreed service level targets in one or more service level agreements.

unit cost

(ITIL Service Strategy) The cost to the IT service provider of providing a single component of an IT service. For example, the cost of a single desktop PC, or of a single transaction.

urgency

(ITIL Service Design) (ITIL Service Transition) A measure of how long it will be until an incident, problem or change has a significant impact on the business. For example, a high-impact incident may have low urgency if the impact will not affect the business until the end of the financial year. Impact and urgency are used to assign priority.

usability

(ITIL Service Design) The ease with which an application, product or IT service can be used. Usability requirements are often included in a statement of requirements.

use case

(ITIL Service Design) A technique used to define required functionality and objectives, and to design tests. Use cases define realistic scenarios that describe interactions between users and an IT service or other system.

user

A person who uses the IT service on a day-to-day basis. Users are distinct from customers, as some customers do not use the IT service directly.

user profile (UP)

(ITIL Service Strategy) A pattern of user demand for IT services. Each user profile includes one or more patterns of business activity.

utility

(ITIL Service Strategy) The functionality offered by a product or service to meet a particular need. Utility can be summarized as 'what the service does', and can be used to determine whether a service is able to meet its required outcomes, or is 'fit for purpose'. The business value of an IT service is created by the combination of utility and warranty. See also service validation and testing.
