About this routine

Product growth relies on understanding whether users perform the central action that delivers real value. An amplitude critical event audit routine provides a clear framework for product teams to identify that pivotal action, check event taxonomy quality, and establish baseline cohort curves.

Amplitude pioneered the critical event framework to help software teams look beyond generic active user metrics. By zeroing in on the specific action that signals genuine value exchange, teams can measure habit formation with precision.

Executing this audit in a structured 45 minute working session brings product managers, data analysts, and designers onto the same page regarding activation criteria and retention health.

Why this routine works

Identifies the single action tied to long-term user retention
Eliminates noise from vanity metrics and superficial logins
Establishes a realistic usage interval for cohort analysis
Creates a shared definition of active users across product teams

FAQ

What is a critical event in Amplitude?

A critical event is the specific action in your product that indicates a user derived core value, such as booking a room or sending a message.

How long does a critical event audit take?

This structured team workshop takes exactly 45 minutes when using pre-collected Amplitude analytics data.

Why is finding the usage interval important for retention?

The usage interval tells you how often active users naturally return, preventing inaccurate retention calculations for non-daily products.
