You are working as PM of a social media app. You noticed that DAU of the app fell by 50%. How would you figure out what might have happned?

Introduction

A 50% drop in Daily Active Users (DAU) for a social media app is a critical issue that demands immediate attention and a thorough investigation. This significant decline could have far-reaching consequences for user engagement, revenue, and overall product health. I'll approach this problem systematically, focusing on identifying potential root causes, validating hypotheses, and developing both short-term and long-term solutions.

Step 1

Clarifying Questions (3 minutes)

• What's the typical DAU for our app, and over what timeframe did we observe this 50% drop?

• Have we seen any changes in user demographics or behavior patterns recently?

• Were there any recent product updates, feature launches, or backend changes?

• Are there any known technical issues or outages that coincided with the DAU drop?

• Has there been any significant change in our marketing or user acquisition strategies?

• Are we seeing similar trends across all user segments and geographies?

Why these questions matter: Understanding the context and timeline of the DAU drop is crucial for narrowing down potential causes. Knowing about recent changes or issues can help us quickly identify likely culprits.

Hypothetical answer: Let's assume the DAU dropped from 1 million to 500,000 over the past week, coinciding with a major app update. This information would immediately focus our investigation on the recent update and its potential impact on user experience.

Impact on solution approach: If the drop coincided with an update, we'd prioritize analyzing the changes introduced and their effects on user behavior. We'd also need to consider the possibility of a technical issue introduced by the update.
