What is the difference between a 'request for change' and an 'emergency change'?

The distinction between a 'request for change' and an 'emergency change' in ITIL is primarily rooted in the urgency and authorization process. An emergency change is necessitated by critical situations that require immediate action to prevent significant disruption or to restore service functionality. Consequently, the approval process for emergency changes is expedited to allow for faster implementation. This contrasts with a standard 'request for change,' which follows a more deliberate and structured approval process, typically requiring thorough assessment and formal documentation.

Emergency changes are often unplanned and may be initiated in response to unforeseen incidents, making the swift authorization crucial in mitigating risks and minimizing downtime. In contrast, standard requests for change can encompass a variety of alterations, including planned upgrades or routine maintenance, and they provide a more comprehensive evaluation of potential impacts, risks, and benefits before proceeding. Understanding these different contexts highlights the importance of organizational flexibility in responding to urgent needs without compromising overall change governance.
