Six Sigma Project KPIs

KPIS are crucial throughout the implementation process. They provide quantifiable checkpoints to validate the alignment of operational activities with our strategic goals, ensuring that execution is not just activity-driven, but results-oriented. Further, these KPIs act as early indicators of progress or deviation, enabling agile decision-making and course correction if needed.


What gets measured gets done, what gets measured and fed back gets done well, what gets rewarded gets repeated.
     – John E. Jones

  • Defect Rate: Tracks the frequency of defects post-implementation to measure quality improvements.
  • Customer Satisfaction Score: Gauges customer perceptions of quality and service to ensure market competitiveness.
  • Process Cycle Time: Measures the efficiency of the process flow and identifies areas for further improvement.
