Golden metric selection criteria¶
Definition¶
Golden metric selection criteria is a governance gate that determines which metrics are important enough to be centrally governed in a semantic layer. Not all metrics warrant the overhead of centralized ownership, dual-owner approval, and package distribution — only those that cross team boundaries and have multiple consumers.
Lyft's threshold¶
At Lyft, a metric qualifies as a "Golden Metric" if it has at least two distinct use cases or applications (e.g., monitored on key dashboards AND leveraged in operational ML models). Anything too niche — unique to one team — creates more governance overhead than it's worth.

Why it matters¶
Without a selection gate, a centralized metric layer becomes a dumping ground of team-specific metrics, diluting the value of the "single source of truth" promise and increasing maintenance burden. The threshold forces teams to demonstrate cross-cutting importance before onboarding.
