Peter Drucker once famously said that the only metrics that matter to a business come from outside the business.

A successful restaurant has some number of humans who've left fed and happy. A successful hospital takes in patients and healthy people walk out. Every internal number a business produces for itself might be informative or useful but does not ultimately matter.

Whenever I see companies spouting about their internal metrics like they're proud of them, I think, bluntly: who cares?
