What factors contributed to the 30% drop in StoreDot's XFC cell production yield at our pilot plant last month?

Introduction

The 30% drop in StoreDot's XFC cell production yield at our pilot plant last month is a critical issue that demands immediate attention and thorough analysis. To address this problem, I'll employ a systematic approach to identify, validate, and resolve the root cause while considering both short-term and long-term implications for our production process and overall business strategy.

Clarifying Questions (3 minutes)

• Given the sudden drop, I'm wondering about recent changes. Have there been any modifications to the production process or equipment in the past 1-2 months?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: Yes, we upgraded some equipment last month. Impact on approach: If confirmed, I'd focus on the new equipment's integration and calibration.

• Considering the scale of the drop, I'm curious about quality control. Has there been any change in our QC processes or standards recently?

Why it matters: QC changes could explain yield variations without actual production issues. Expected answer: No changes to QC processes. Impact on approach: If unchanged, I'd look deeper into production variables.

• Thinking about supply chain, have we experienced any changes or disruptions in our raw material sourcing?

Why it matters: Material quality directly impacts production yield. Expected answer: Some supply chain disruptions occurred. Impact on approach: I'd investigate material quality and consistency if confirmed.

• Reflecting on our workforce, have there been any significant changes in staffing or training programs?

Why it matters: New or untrained staff could affect production quality. Expected answer: Normal staff turnover, no major changes. Impact on approach: If stable, I'd focus more on technical and process-related factors.
