Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent system update. Has there been any software or hardware changes to the robotic picking system in the past month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, a software update was implemented two weeks ago. Impact on approach: If confirmed, we'd focus on the update's impact and potential rollback.

• Considering the scale of the increase, I'm wondering about environmental factors. Have there been any significant changes in warehouse conditions, such as temperature or humidity?

Why it matters: Environmental changes can affect robotic performance. Expected answer: No significant environmental changes noted. Impact on approach: If no changes, we'd shift focus to internal system factors.

• Given the specificity of the increase, I'm curious about the measurement process. Has there been any change in how pick time is measured or calculated?

Why it matters: Ensures we're comparing apples to apples in our metrics. Expected answer: No changes in measurement methodology. Impact on approach: If confirmed, we can rule out measurement errors and focus on actual performance issues.

• Thinking about potential physical changes, have there been any modifications to the warehouse layout or inventory organization in the past month?

Why it matters: Physical changes can significantly impact robotic navigation and picking efficiency. Expected answer: Minor reorganization of some inventory sections. Impact on approach: If confirmed, we'd investigate the correlation between reorganized areas and increased pick times.
