gap analysis

(ITIL Continual Service Improvement) An activity that compares two sets of data and identifies the differences. Gap analysis is commonly used to compare a set of requirements with actual delivery. See also benchmarking.

governance

Ensures that policies and strategy are actually implemented, and that required processes are correctly followed. Governance includes defining roles and responsibilities, measuring and reporting, and taking actions to resolve any issues identified.

gradual recovery

(ITIL Service Design) A recovery option that is also known as cold standby. Gradual recovery typically uses a portable or fixed facility that has environmental support and network cabling, but no computer systems. The hardware and software are installed as part of the IT service continuity plan. Gradual recovery typically takes more than three days, and may take significantly longer.

guideline

A document describing best practice, which recommends what should be done. Compliance with a guideline is not normally enforced. See also standard.

hierarchic escalation

(ITIL Service Operation) Informing or involving more senior levels of management to assist in an escalation.

high availability

(ITIL Service Design) An approach or design that minimizes or hides the effects of configuration item failure from the users of an IT service. High availability solutions are designed to achieve an agreed level of availability and make use of techniques such as fault tolerance, resilience and fast recovery to reduce the number and impact of incidents.

hot standby

See fast recovery; immediate recovery.
