Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent system update. Has there been any significant change to the Entity Resolution algorithm or data sources in the past 1-2 months?

Why it matters: System changes often correlate with performance shifts. Expected answer: Yes, there was a recent update. Impact on approach: If yes, we'd focus on the update's impact; if no, we'd look at other factors.

• Considering user segments, I'm curious about the distribution of this accuracy drop. Is the 5% decrease uniform across all customer types, or is it more pronounced in specific industries or data sets?

Why it matters: Helps identify if the issue is systemic or localized. Expected answer: The drop varies across segments. Impact on approach: Uniform drop suggests a system-wide issue; varied drop points to segment-specific factors.

• Thinking about data quality, has there been any change in the input data characteristics or volume over the past month?

Why it matters: Data quality directly impacts Entity Resolution accuracy. Expected answer: Some changes in data patterns or volume. Impact on approach: If yes, we'd investigate data quality issues; if no, we'd focus more on algorithmic factors.

• Considering performance metrics, has the definition or measurement method for accuracy rate changed recently?

Why it matters: Ensures we're comparing apples to apples. Expected answer: No change in definition or measurement. Impact on approach: If changed, we'd need to reassess the actual performance impact.

• Reflecting on user feedback, have there been any notable complaints or support tickets related to Entity Resolution accuracy in the past month?

Why it matters: User feedback can provide qualitative insights into quantitative issues. Expected answer: Some increase in related complaints. Impact on approach: If yes, we'd analyze these complaints for patterns; if no, we'd focus more on internal metrics.
