It would be helpful to have an average Time to Patch metric for Advanced Insights for Intune, which i believe exists for ConfigMgr reporting.
Ideally, this would show the average time between an application update becoming available and successful deployment, with breakdowns by application and trends over time.
This would give us a useful KPI for measuring patching performance and how quickly application updates and vulnerabilities are remediated across our Intune-managed estate.
To add some additional context after working with Michael in 00039169; I feel the Trend dashboard from Advanced Insights for ConfigMgr would be ideal here. While the Trend dashboard doesn't give the customer the average time calculation, it does show the rate of compliance over time for any given patch against a given collection/group.
