Privacy Metrics Dashboard
Overview
A privacy metrics dashboard provides quantitative visibility into the effectiveness and maturity of an organization's privacy program. This skill defines the key privacy performance indicators (KPIs), data collection methods, visualization patterns, and reporting cadences needed to measure, monitor, and continuously improve privacy operations.
Core Privacy KPI Categories

| DSAR by Type | Breakdown by right exercised (access, deletion, portability, rectification) | N/A (distribution) | Monthly |
| Average Response Time | Mean calendar days from receipt to completion | < 25 days (GDPR: 30 day limit) | Monthly |
| Median Response Time | Median calendar days from receipt to completion | < 20 days | Monthly |
| P95 Response Time | 95th percentile response time | < 28 days | Monthly |
| On-Time Completion Rate | % completed within regulatory deadline | > 98% | Monthly |
