Problem Solved
Product organizations suffer from telemetry chaos: inconsistent event naming, unmonitored drop-off funnels, untracked feature adoption, and vanity metrics disconnected from business revenue.
When to Use
- •Establishing formal tracking standards before launching new product features
- •Implementing Google HEART metrics or North Star input-metric trees across squads
- •Auditing and deduplicating client and server analytics events during telemetry refactors
When NOT to Use
- •For infrastructure-only CPU/memory APM metric definitions (use TPL-OPS-004)
- •For corporate statutory accounting financial ledgers (use TPL-FIN-004)

Frequently Asked Questions
How does a North Star metric differ from company revenue OKRs?
Company revenue is an outcome lag metric; the North Star metric is an operational lead indicator that measures the core moment of customer value delivery which predictably drives future revenue.
What is the recommended event naming convention for product telemetry?
We recommend snake_case object-action format, such as workspace_created, document_exported, or billing_plan_upgraded, with standardized properties like user_id, tenant_id, and platform.
How often should the product event taxonomy be audited?
Telemetry taxonomies should undergo automated regression testing in CI/CD continuously, alongside a quarterly manual review to deprecate orphaned and obsolete events.
