  • Analyze: Identify root causes of issues within processes. Example Tools: Pareto charts, cause-and-effect diagrams.

  • Improve: Implement solutions to enhance performance and achieve desired outcomes. Example Tools: Brainstorming, pilot testing.

  • Control: Maintain improvements through ongoing monitoring and control systems. Example Tools: Control charts, standard operating procedures (SOPs).

Lean Six Sigma Certification Levels

  • Certifications range from Yellow to Master Black Belts, indicating levels of expertise.

Quality Philosophies

  • Goal Post Philosophy: Quality loss occurs outside spec limits.
  • Taguchi Philosophy: Any deviation from target results in quality loss.
