Customer's will notice that an audit hasn't been completed on a device. (Not Audited as shown below)
By default NCM will complete a Compliance Audit when a device is installed or when changes are completed on a device. So customer's will notice that some devices will not have an Audit check mark and other devices will have an Audit Check. To resolve the issue the customer will just need to run "Enforce Policy" by right clicking on the device. You can select as many devices as you want and then right click and select "Enforce Policy".
