4.2.6.5 Authorizing the change
Formal authorization is obtained for each change from a
change authority that may be a role, person or a group of
people. The levels of authorization for a particular type of
change should be judged by the type, size or risk of the
change, e.g. changes in a large enterprise that affect
several distributed sites may need to be authorized by a
higher-level change authority such as a global CAB or the
Board of Directors.
