ITIL Service Strategy) A
cost that depends on how much the
IT service is used, how many products are produced, the number and type of users, or something else that cannot be fixed in advance.
variance
The difference between a planned value and the actual measured value. Commonly used in financial management, capacity management and service level management, but could apply in any area where plans are in place.
version
(
ITIL Service Transition) A version is used to identify a specific
baseline of a
configuration item. Versions typically use a naming convention that enables the sequence or date of each
baseline to be identified. For example, payroll application version 3 contains updated functionality from version 2.

IT service continuity management and availability management.
vulnerability
A weakness that could be exploited by a threat – for example, an open firewall port, a password that is never changed, or a flammable carpet. A missing control is also considered to be a vulnerability.
