Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a recent change. Has there been any significant update to our SMS marketing platform in the past two weeks?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, we rolled out a new template system. Impact on approach: If yes, we'd focus on the new feature's impact; if no, we'd look at external factors or gradual changes.

• Considering user segments, I'm curious about the distribution. Is this 15% decrease uniform across all customer segments or more pronounced in specific groups?

Why it matters: Helps identify if the issue is global or segment-specific. Expected answer: The decrease is more significant in our B2C segment. Impact on approach: A segment-specific issue would narrow our focus to that particular user group and their unique characteristics.

• Thinking about seasonality, does this time of year typically see fluctuations in SMS marketing performance?

Why it matters: Rules out normal seasonal variations. Expected answer: No, this is usually a stable period for us. Impact on approach: If seasonal, we'd adjust our baseline; if not, we'd focus on recent changes or external factors.

• Regarding system integrity, have there been any changes to our tracking or analytics systems that might affect how we measure conversion rates?

Why it matters: Ensures the observed decrease is real and not a measurement error. Expected answer: No changes to our analytics systems. Impact on approach: If yes, we'd first validate our measurement systems; if no, we'd focus on actual performance issues.
