Where would you describe analytics before launching the application?

Would describe in the following places:

• Technical specification/Project documentation: Detailed description of the collected events, their parameters, triggers, and analytics goals.
• Application code: In places where event sending functions are called, with comments explaining their purpose and the data collected.

  // Sending event on successful registration
  analyticsManager.trackEvent(
      "registration_success",
      mapOf("method" to "email_password")
  )
  

• Task management system (Jira, Asana, etc.): In individual tasks or epics related to analytics implementation, describing specific requirements and implementation steps.
• Confluence or other wiki system: For a higher-level description of the analytics strategy, tools used, dashboards, and success metrics.
