This is an enumerated value classifying the nature of the impact this analysis found -- for example a disruptive reboot, a non-disruptive update, or no impact at all. An admin scanning a batch of impact records before a maintenance window filters on this field to separate the changes that will actually cause downtime from the ones that won't, so they can schedule accordingly. A type of 'disruptive' on this record means the proposed change to this specific piece of equipment cannot be applied without some service interruption, as opposed to a 'none' or 'nonDisruptive' value elsewhere.
