In the ITIL 4 framework, ensuring that events are detected, interpreted, and acted upon quickly is a critical aspect of the "Monitoring and Event Management" practice. The success of this practice hinges on the availability of relevant monitoring data when needed and its alignment with user requirements.

The capability criterion that supports this practice focuses on the timely availability and relevance of monitoring data. If the data is not available or does not meet the needs of the users, it will hinder the ability to respond swiftly and accurately to events. Therefore, ensuring that the monitoring data is consistently available and relevant is crucial to detecting, interpreting, and acting on events as they occur​​.

Other options:

B. Responsibility for the approach is defined: While important, this option focuses on process ownership rather than the immediate availability of data.

C. Identifying key users and their requirements: Identifying users is essential but does not directly support the criterion of fast response.

D. Trends are analyzed: Trend analysis helps in long-term predictions, but this does not directly support real-time event handling.
