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 automation system in the last 1-2 months?

Why it matters: Recent changes could directly impact picking accuracy. Expected answer: Yes, a software update was implemented. Impact on approach: If confirmed, we'd focus on the update's specifics and rollback options.

• Considering the scale of the issue, I'm wondering about its consistency. Is the 15% decrease uniform across all product types and warehouse sections?

Why it matters: Helps identify if the problem is systemic or localized. Expected answer: The decrease varies across different areas. Impact on approach: We'd prioritize investigating the most affected areas first.

• Given the nature of automation, I'm curious about any changes in inventory layout. Have there been any modifications to the warehouse layout or product placement recently?

Why it matters: Layout changes could confuse the automation system. Expected answer: Some layout optimizations were made last month. Impact on approach: We'd examine the correlation between layout changes and accuracy drops.

• Thinking about external factors, I'm considering seasonal influences. Has there been a significant increase in order volume or complexity compared to the same period last year?

Why it matters: Unusual demand patterns could strain the system. Expected answer: Order volume is up 20% year-over-year. Impact on approach: We'd analyze if the system is adequately scaled for increased demand.
