Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent update. Has there been any software or algorithm changes in the past 1-2 months?

Why it matters: Recent changes could directly impact accuracy. Expected answer: Yes, there was an update to improve processing speed. Impact on approach: If confirmed, we'd focus on the update's impact on accuracy.

• Considering user segments, I'm curious about the data distribution. Has there been any change in the types or sources of breast cancer images being analyzed?

Why it matters: Changes in input data could affect accuracy rates. Expected answer: No significant changes in data sources. Impact on approach: If unchanged, we'd look more closely at internal factors.

• Thinking about performance metrics, I wonder about the accuracy measurement itself. Has there been any change in how accuracy is calculated or in the ground truth data used for comparison?

Why it matters: Changes in measurement could explain the perceived drop. Expected answer: No changes in accuracy calculation methods. Impact on approach: If confirmed, we'd focus on actual performance issues rather than measurement discrepancies.

• Considering external factors, I'm wondering about any recent regulatory changes or industry standards updates. Have there been any new guidelines or requirements for breast cancer detection tools?

Why it matters: External changes could necessitate adjustments to our tool. Expected answer: No significant regulatory changes. Impact on approach: If confirmed, we'd focus more on internal factors and tool-specific issues.
