Why Does GE Need A Quality Initiative? GE Raising The Bar New Goal to be “Best in the World” vs. #1 or #2 Customers are Expecting More, we Must Deliver “Ship-and-fix” Approach no Longer Tolerated in the Market Aim to Speed Past Traditional Competitors in 5 Years Goal Consistent with Reduced Total Costs We Must Acknowledge Our Vulnerabilities Poor Quality That Impacts Customers Problems with NPI Too High Internal Costs Why “Six Sigma”? Proven Successful in “Quality-Demanding” Industries e.g., Motorola, Texas Instruments (many process steps in series) Proven Method to Reduce Costs Highly Quantitative Method – Science and Logic Instead of Gut Feel Includes Manufacturing Service (close to customer) and Provides Bridge to Design for Quality Concepts Has Support and Commitment of Top Management 6?
