Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in our data processing pipeline. Has there been any significant update to our analytics infrastructure in the past month?

Why it matters: Recent changes could directly impact accuracy. Expected answer: Yes, there was a major update two weeks ago. Impact on approach: If confirmed, we'd focus on post-update data discrepancies.

• Considering user segments, I'm wondering if this accuracy drop is uniform across all user types. Are we seeing any differences in accuracy between, say, business accounts and personal accounts?

Why it matters: Helps identify if the issue is user-segment specific. Expected answer: Business accounts seem more affected. Impact on approach: We'd investigate business account-specific features or data flows.

• Thinking about the metric itself, I'm curious if we've recently changed how we define or calculate reach. Has the definition of reach remained consistent over the past quarter?

Why it matters: Ensures we're comparing apples to apples. Expected answer: No changes to the definition. Impact on approach: If changed, we'd need to reassess our baseline accuracy.

• Considering external factors, I'm wondering about any recent API changes or third-party integrations. Have we integrated any new data sources or changed our data providers recently?

Why it matters: External data sources could introduce inconsistencies. Expected answer: We added a new third-party data provider last month. Impact on approach: We'd scrutinize the integration and data quality from this new source.
