The Analytical Process (DMAIC Framework)

01

ETL & Data Transformation (Define & Measure)

Leveraged Power Query to merge disparate data sources into a unified fact table.

  • Unpivoted 12 columns of downtime factors into a "tall" schema
  • Cleaned production records for consistency across shifts
  • Calculated efficiency metrics considering overnight overlaps
02

Down-Time Segmentation (Analyze)

Partitioned downtime into "Operator-Controllable" and "Systemic" categories to ensure fair performance assessment.

Operator Errors
Training Opportunities
Systemic Issues
Maintenance & Supply Chain
03

Root Cause Identification (Improve & Control)

Deployed Pareto analysis to isolate the "Vital Few" factors—specifically machine failure and inventory shortages—that drove 80% of lost time.

Downtime Drivers

Identified that Machine Adjustments and Inventory Shortages were the primary bottlenecks, not operator speed.

Productivity Levers

The CO-600 product line demonstrated the highest variance in downtime, suggesting equipment issues specific to that format.

Strategic Recommendation

"Shift from reactive machine fixing to a preventative maintenance schedule prioritized for the CO-600 line equipment and high-incidence adjustment phases."
