Level 3 Metrics are the base of the 📝Instrumentation Pyramid: the metrics of a business's basic integrity, showing whether its people trust one another and whether its customers like the product enough to keep it and buy it again.
The Instrumentation Pyramid arranges a company's metrics in three levels. 📝Level 1 Metrics, also called 📝Vital Signs, are the minimal set needed to forecast the business. Level 2 metrics break those down to run it, for example web traffic by source, gross margin by product, or lifetime value by cohort, as in 📝Level 2 Marketing Metrics. Level 3 sits beneath both. The pyramid drawing also describes this level as the real-time transaction metrics of the business, the raw activity from which the levels above are built.
As measures of integrity, Level 3 metrics look at two relationships. Inside the company, people trust one another and are surrounded by colleagues who trust them. Outside it, customers are generally happy with how the product performs: they don't return it very often, and they buy it again. Like the rest of the pyramid, the levels are fractal; each department, customer, or employee can carry its own three levels of metrics.
I trust you. You trust me. We have people around us who we trust and who trust us.
