Which capability criterion supports the practice success factor 'establishing and maintaining approaches/models that describe the various types of events and monitoring capabilities needed to detect them'?

A Practice Success Factor (PSF) is an essential component for a practice to achieve its purpose. The PSF of 'establishing and maintaining approaches/models' requires a clear foundation. A key capability criterion that enables this is ensuring that responsibility for the approach is clearly defined and assigned. Without clear ownership, any approach or model is unlikely to be established effectively, consistently maintained, or improved over time.

A. Detected events are interpreted and acted upon, where relevant: This is a criterion for a different PSF related to the operational processing of events, not establishing the initial approach.
C. The quality of monitoring data is measured and reported: This supports a PSF focused on ensuring the monitoring itself is effective, not the establishment of the overall approach.
D. The monitoring data is available when needed and meets the user requirements: This also supports a PSF related to the operational effectiveness and quality of the monitoring data.

Section 2.2.3, Table 2.1: This table explicitly lists the PSFs for the Monitoring and Event Management practice. For PSF 1, "Establish and maintain a monitoring approach that supports stakeholder needs," the first capability criterion listed is "The responsibility for the approach to monitoring and event management is clearly defined."
