Step 1

Clarifying Questions (3 minutes)

• What specific user segments are most affected by this drop?

• Have there been any recent product updates or changes to the voice call feature?

• Are there any regional patterns in the user decline?

• Has there been any change in how we measure daily active users for voice calls?

• What's the normal week-to-week fluctuation for this metric?

• Have we observed any changes in competing products or market conditions?

These questions are crucial for understanding the context and scope of the issue. For example, knowing which user segments are most affected could point to specific usability or technical problems. Information about recent updates could reveal unintended consequences of product changes.

Hypothetical answers might include a disproportionate drop among Android users, a recent update that changed the UI for initiating calls, or a new competitor entering key markets. Each of these would significantly impact our approach to solving the problem.
