My 6𝜎 Black belt project

Led a full-cycle Six Sigma Black Belt project to reduce dispatch documentation errors that were causing costly supply chain disruptions in a transportation and logistics operation. Applied the DMAIC framework to identify root causes, implement corrective actions, and sustain improvements.

• Define: Established project scope and stakeholder alignment; documented the problem through a SIPOC diagram and charter.

• Measure: Analyzed dispatch error rates using historical logs and baseline metrics; identified variation and error frequency trends.

• Analyze: Performed root cause analysis using Cause & Effect diagrams, FMEA, and COPQ; isolated breakdowns in documentation handoff and accountability.

• Improve: Piloted standardized checklists, peer reviews, and visual cues to streamline documentation. Used QFD and DOE to align changes with customer priorities and validate effectiveness.

• Control: Instituted a formal control plan with SPC charts, audit checklists, SOPs, and dashboards; improved compliance from 65% to 98% and reduced errors by over 60%.

Results:

• Reduced weekly documentation errors from 6.0 to 2.0

• Increased SOP compliance from 65% to 98%

• Improved process capability from ~2.5σ to ~4.1σ

• Cut detention-related costs by over 50%

• Established a sustainable framework for continuous improvement
