Error Proofing 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: Monitor the percentage of products with defects post-implementation to measure improvement.
  • Recall Frequency: Track the number of recalls as an indicator of product quality and error proofing effectiveness.
  • Training Completion: Measure the percentage of staff who have completed the new error proofing training programs.
  • Customer Satisfaction Scores: Use customer feedback as a gauge for the success of quality improvements.
