@Mike_Eastwood Hi Mike, I know this is an old post and I am trying my luck. Are you still open to sharing ideas? This is our current project to get better visibility into customer health.
This is a good question. The usage of interactions, number of tickets, etc. is really difficult to gauge customer happiness on because there is no context and it is very subjective. You could build a report and scoring model from this, but it may not give you accurate scores. The best way to get accurate scores in my opinion is through NPS surveys/scores, customer happiness surveys, or a more objective point modeling system.
