When to Use

Planning event tracking for product, marketing, or revenue analytics.
Auditing existing tracking plans before model refreshes.
Coordinating engineering, product, and RevOps on data contracts.

Framework

Consent & Privacy – capture consent status, honor suppression, regional storage rules.
Versioning – change logs, backward compatibility, deprecation timelines.

Templates

Tracking plan sheet (event, description, properties, source, owner, status).
Data contract checklist (fields, types, validation rules, SLA).
Observability runbook (metrics, thresholds, notification channels).

Tips

Pair each event with QA instructions and sample payloads.
Store tracking plans in version control to align with code releases.
Review instrumentation quarterly with stakeholders.
