Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent app update. Has there been any significant changes or updates to the app in the last 1-2 weeks?

Why it matters: App updates can introduce bugs or UI changes that deter new users. Expected answer: Yes, there was an update released 10 days ago. Impact on approach: If confirmed, I'd focus on analyzing the changes in that update.

• Considering user segments, I'm curious about the distribution of this decrease. Is the 30% drop uniform across all user segments, or is it more pronounced in specific groups?

Why it matters: Helps identify if the issue is global or segment-specific. Expected answer: The drop is more significant among younger users (13-17 age group). Impact on approach: I'd investigate factors specifically affecting this age group.

• Given the suddenness of the drop, I'm wondering about any changes in marketing efforts. Have there been any significant shifts in marketing strategies or budget allocation recently?

Why it matters: Changes in user acquisition channels can directly impact sign-up rates. Expected answer: No major changes in marketing efforts. Impact on approach: I'd focus more on product and technical issues rather than marketing.

• Considering potential technical issues, has there been any reported downtime or performance issues with the app or sign-up process in the past week?

Why it matters: Technical problems can severely impact user sign-ups. Expected answer: No significant downtime, but there have been some reports of slower app performance. Impact on approach: I'd investigate the app's performance metrics more closely.
