Which situation exemplifies the need for an Emergency change?

The situation that exemplifies the need for an Emergency change is a security patch for known vulnerabilities. In the context of IT Service Management, an Emergency change is necessary when there’s an immediate need to resolve a critical issue that poses a risk to the organization, such as a security breach or system vulnerability.

Applying a security patch is urgent because it is essential to protect sensitive data, maintain compliance with regulations, and safeguard the integrity of IT services. The prompt implementation of such changes helps to mitigate risks and prevent potential harm to the organization.

In contrast, options such as updates to low-risk application features, process changes requiring user training, and scheduled software maintenance typically follow standard change management procedures. These do not typically demand immediate action and allow for adequate planning and testing before deployment, which is not the case for situations requiring Emergency changes.
