How to Track the Supporting Metrics of a Product or Service

In customer service, a norstarmetric that says transactions per day doesn't make as much sense because it's not immediately actionable. So we try to adjust the metric for fina measurability, and we do that by proxies. Proxies are needed when the overall impact of the nonstametric is either small or its delayed. A some examples of approxy, a on time delivery can be a primary metric for logistics rather than the frequency of transactions or the number of transactions.
