A service operations team monitors a critical service.

The best approach is to review and automate filtering of operations data (D). The ITIL 4 Specialist: Create, Deliver and Support guide (Section 4.2.4) states: "Automation of event filtering reduces human error by prioritizing critical events, ensuring operators focus on what matters and preventing breaches of service level targets." This leverages technology to address misses, unlike option A (costly staffing), option B (insufficient if overwhelmed), or option C (avoiding the root cause). The guide notes: "Effective event management relies on automated tools to enhance reliability."
