You are the PM of Messenger, you noticed that its DAU has gone down significantly. How would you go about looking for the root cause?

Introduction

The sudden decline in Messenger's Daily Active Users (DAU) is a critical issue that demands immediate attention and a systematic approach to uncover the root cause. As the Product Manager, I'll employ a structured framework to analyze this problem, generate data-driven hypotheses, and develop a comprehensive plan to address the underlying issues.

Clarifying Questions (3 minutes)

• What's the exact percentage of DAU decline, and over what time frame?

• Are there specific user segments or geographic regions more affected?

• Have we recently rolled out any major updates or changes to Messenger?

• Are there any known technical issues or outages during this period?

• Has there been any significant change in our competitors' offerings?

• Have we altered our measurement methodology or tracking systems recently?

Why these questions matter: Understanding the scope, timeline, and context of the DAU decline is crucial for accurate analysis and targeted solutions.

Hypothetical answer: Let's assume a 15% DAU drop over the past month, primarily affecting users in North America and Europe, with no recent major updates or known technical issues.

Impact on solution approach: This information narrows our focus to regional factors and recent changes that might have impacted user engagement in specific markets.
