Mean Time to Triage Metrics
Mean time to triage measures how long it takes to review an alert or intake item, determine initial disposition, and decide whether further action is required.
Why This Measurement Matters
Timely triage reduces dwell time, limits potential harm, and improves confidence that material signals are not sitting unattended.
Interpretation Strategy
Segment triage time by severity, source, business unit, analyst capacity, and required cross-functional input.
Recommended Measurement Metrics
Mean time to triage
Measure the speed and quality of initial signal analysis, ensuring critical alerts are escalated within target SLA parameters.
Median time to triage
Measure the speed and quality of initial signal analysis, ensuring critical alerts are escalated within target SLA parameters.
Priority-one triage time
Measure the speed and quality of initial signal analysis, ensuring critical alerts are escalated within target SLA parameters.
Aged untriaged alerts
Measure the speed and quality of initial signal analysis, ensuring critical alerts are escalated within target SLA parameters.
Triage SLA attainment
Establish visibility, baseline usage patterns, and monitor for anomalous interactions with public and private AI tools.
Time awaiting enrichment
Establish visibility, baseline usage patterns, and monitor for anomalous interactions with public and private AI tools.
Time awaiting legal/privacy input
Establish visibility, baseline usage patterns, and monitor for anomalous interactions with public and private AI tools.
Triage backlog volume
Measure the speed and quality of initial signal analysis, ensuring critical alerts are escalated within target SLA parameters.
Reopened triage decisions
Measure the speed and quality of initial signal analysis, ensuring critical alerts are escalated within target SLA parameters.
Triage disposition quality
Measure the speed and quality of initial signal analysis, ensuring critical alerts are escalated within target SLA parameters.
Common Pitfalls to Avoid
- Reporting activity volume without explaining risk or exposure relevance.
- Reporting improvement before confirming coverage and data quality.
- Using metrics to imply individual misconduct without appropriate context and review.
- Mixing operational details with executive governance reporting.
- Treating tool output as a final decision rather than an input to review.
