  1. Six Sigma - A Breakthrough Strategy Competitive Edge Management Consultants

  2. Visible and hidden costs Visible costs • Scrap • Rework • Warranty Hidden Costs • Conversion efficiency of materials • Inadequate resource utilization • Excessive use of material • Cost of redesign and re-inspection • Cost of resolving customer problems • Lost customers / Goodwill • High inventory

  3. The Six Sigma roadmap- Breakthrough strategy Stage Phase Objective Identify key business issues Define Identification Understand current performance levels Measure Analyze Characterization BREAKTHROUGH STRATEGY Improve Control Achieve breakthrough improvement Optimization Integrate Six Sigma in day to day functioning.
