Which of the following is a key objective of event management?

A key objective of event management is to provide a means to compare actual performance against designs. This objective plays a crucial role in ensuring that IT services are aligned with business needs and expectations. By monitoring events and performance metrics, organizations can assess whether the services are functioning as intended and meeting agreed-upon standards.

This alignment is critical for maintaining service quality and provides insights into areas where improvements might be necessary. Additionally, by comparing actual performance to planned designs, it becomes easier to identify trends, performance bottlenecks, or potential failures before they affect service delivery, thus enabling proactive management of the IT environment.

The other options focus on different areas within IT service management. Modifying the infrastructure pertains more to capacity and change management, while detecting insignificant changes does not align with the purpose of event management, which primarily focuses on identifying important events and alerts. Lastly, establishing service agreements is generally related to service level management rather than event management, which centers around monitoring and reporting on service performance.
