+====== Six Sigma ======
+Currently I am learning 'Becoming Six Sigma Green Belt' on linkedin learning. Below are keypoint I learned.
+===== Operational Excellence =====
+  * Operational Excelence: better, faster, cheaper
+  * 3 roles: customer, processor, supplier
+  * Voice of customer VOC >> Critical to quality CTQ >> Metrics
+  * Performance attributes is categorized to three (kano model): dissatisfier, satisfier, and delighter.
+  * Variation; controlling variation within specification limit is key. Mean, variance, stdev, LCL, UCL.
+  * Quality at the source: (1) Quality by design (2) Quality by process monitoring & control (3) Quality by self check and verification
+  * Pokayoke: prevention, facilitation, detection
+  * Lean principles: principle to maximize customer value by minimizing waste. 8 waste: TIMWOODS, Travel, Inventory, Motion, Waiting, Overproduction, Overprocessing, Defects, Skill underutilized
+  * Process Mapping: detail, swimlane, value stream map
+  * FMEA: Design FMEA, Process FMEA
+  * Control plan
+  * Key Roles in op excellence; project champion; 1. Design for six sigma 2. Six sigma and lean 3. Process monitoring
+  * Alignment of kpi. 1) Reduce KPI 2) Vertical line sight 3) Horizontal line sight
+  * Choose right methodology: 1) Process Management 2) Project 3) Lean Project 4) Six Sigma DMAIC 5) Six sigma for design DMADV 6)SIPOC
+  * Process/value stream management: 1)Stdzd work 2) Control plan 3)Process metric & KPI
+  * Lean Event or Kaizen Event or Workout to get improvement from first hand executor/operator. It is guided by kaizen facilitator
+  * Six Sigma DMAIC for problem with unknown cause: Define, Measure, Analyze, Improve, Control
+  * DFSS, Design for Six Sigma used for design/redesign product/process/service. Steps: DMADV, Define, Measure, Analyze, Design, Verify
+  * Challanges for implementation op excellence: fear of job cut, resistance to changes, back to old habit, too many project,
+  * Audit for sustainable implementation
+===== Six Sigma Foundations =====
+  * Six Sigma = Project methodology for improvement
+  * Steps: DMAIC
+  * Role of executives and project champion
+  * Level: White, what is six sigma and why is it useful; Yellow; Green; Black; Master Black Belt
