A change request is a formal communication seeking an alteration to one or more configuration item s. This could take several forms, e.g. ‘ Request for Change ’ document, service desk call, Project Initiation Document. Different types of change may require different types of change request. An organization needs to ensure that appropriate procedure s and forms are available to cover the anticipated requests. Avoiding a bureaucratic approach to documenting a minor change removes some of the cultural barriers to adopting the Change Management process.
As much use as possible should be made of devolved authorization, both through the standard change procedure (see paragraph 4.2.4.4) and through the authorization of minor changes by Change Management staff.
During the planning of different types of change requests, each must be defined with a unique naming convention (see paragraph 4.3.5.3). Table 4.3 provides examples of different types of change request across the service lifecycle.

For different change types there are often specific procedures, e.g. for impact assessment and change authorization.
