You're the new product manager for YouTube and you notice a drop in video engagement by 15% over the past two weeks. What do you do?

Introduction

A 15% drop in YouTube video engagement over two weeks is a significant issue that requires immediate attention. As the new product manager, I'll approach this problem systematically to identify, validate, and address the root cause while considering both short-term fixes and long-term strategic implications.

Step 1

Clarifying Questions (3 minutes)

• What specific metrics are we using to measure video engagement?

• Are there any particular user segments or content types more affected?

• Have there been any recent product updates or changes to the recommendation algorithm?

• Are we seeing any unusual patterns in user behavior or feedback?

• Has there been any change in how we measure or define engagement?

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

Why these questions matter: They help establish a clear baseline and context for the problem, ensuring we're not missing any obvious factors.

Hypothetical answers:

• Engagement is measured by watch time, likes, comments, and shares
• The drop is consistent across user segments but more pronounced in mobile users
• A minor UI update was rolled out three weeks ago
• No significant changes in user feedback or behavior patterns noted
• No changes to engagement definition or measurement
• No major technical issues reported

Impact on approach: These answers would guide us to focus on mobile users and investigate potential UI-related issues while also considering broader factors affecting all users.
