An enterprise is initiating efforts to improve system availability to mitigate IT risk to the business. Which of the following results would be MOST important to report to the CIO to measure progress?

Incident severity and downtime trend analysis directly measure the *impact* and *frequency* of system unavailability, which are precisely the aspects an effort to improve system availability aims to reduce. Tracking these trends provides clear, quantifiable evidence of whether the mitigation efforts are effectively improving the reliability and operational uptime of IT systems.

Probability and severity of each IT risk are important for initial risk assessment and prioritization, but they describe the *potential* risk rather than the actual *progress* in mitigating system availability issues.

Financial losses and bad press releases are consequences of poor availability, but they are lagging indicators; focusing on incident severity and downtime provides more direct and actionable metrics for IT progress.

Customer and stakeholder complaints are important feedback, but they are subjective and often lagging indicators that do not provide the direct, quantifiable operational data needed to measure specific system availability improvements.
