Remediation Momentum

Aging bands mirror the Priority Action Matrix SLAs:

• 0–3d — inside the 72h Critical SLA.
• 4–7d — inside the High SLA.
• 8–30d — inside the Medium SLA.
• 31–90d — past SLA; escalation review.
• 90d+ — ageing risk debt; requires exception approval.

Median-age targets: Critical ≤ 3d, High ≤ 7d, Medium ≤ 30d. If the median for any severity band drifts above target for two weeks running, remediation capacity is the bottleneck — escalate to leadership.
