Clarifying Questions (3 minutes)

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

Why it matters: System changes often correlate with performance fluctuations. Expected answer: Yes, a software update was deployed 6 weeks ago. Impact on approach: If confirmed, we'd focus on the update's impact and potential rollback options.

• Considering the scale of the decrease, I'm wondering about environmental factors. Have there been any significant changes in store layout, lighting, or product placement recently?

Why it matters: Environmental changes can affect computer vision systems' accuracy. Expected answer: No major changes, but seasonal product rotations occurred. Impact on approach: If confirmed, we'd investigate how seasonal changes might affect the system's performance.

• Given the specificity of the 15% figure, I'm curious about our measurement methods. Has there been any change in how we measure or define transaction accuracy?

Why it matters: Ensures we're comparing apples to apples in our metrics. Expected answer: No changes in measurement methodology. Impact on approach: If there were changes, we'd need to re-evaluate our baseline metrics.

• Thinking about user behavior, have we seen any shifts in customer demographics or shopping patterns in the past month?

Why it matters: Changes in user behavior can impact system performance. Expected answer: Slight increase in new customers due to a marketing campaign. Impact on approach: We'd investigate how new user onboarding might affect accuracy.
