Ask AI: What is the difference between a normal change and a standard change in ITIL v4

In ITIL v4, changes in the IT infrastructure or services are managed through the "Change Control" practice. Within that context, two types of changes are commonly referred to: Normal Change and Standard Change. 1. Normal Change: A Normal Change is a non-routine change that usually requires a thorough assessment of potential risks, benefits, and resource requirements. It typically follows a formal change management process that includes the following stages: - Request for Change (RFC): A proposal to modify the IT environment is submitted by a user or a stakeholder. - Change assessment: A Change Advisory Board (CAB) evaluates the change proposal based on impact, urgency, and other risk factors. - Change authorization: If the CAB approves the change, it is granted authorization to proceed. - Change implementation: The authorized change is implemented by IT teams as per the agreed plan. - Post-implementation review: After the change is implemented and effective, its success and impact are reviewed. 2. Standard Change: A Standard Change, on the other hand, is a routine and recurring change that is pre-approved due to its low risk and well-documented nature. Standard changes generally follow a simplified and streamlined change management process as they are considered "business as usual" activities. Examples of standard changes are routine software updates or patches, hardware replacements, or adding new users to a system. Since standard changes have established procedures and known outcomes, they don't require CAB review or extensive planning. Instead, they are monitored at a high level for compliance and performance, and any deviations from expected results are addressed promptly. In summary, a Normal Change is a non-routine, higher-risk change that goes through a formal assessment and approval process, while a Standard Change is a routine, low-risk change that is pre-approved and follows a simplified, streamlined process. The main difference between the two is the level of complexity, risk, and the approach taken for approval and implementation.
