3. 11/13/07 SJSU Bus. 142 - David Bentley 3 Six Sigma Evolution Started as a simple quality metric at Motorola (Bill Smith)
Migrated to Allied Signal
(acquired Honeywell and took its name)
Picked up by General Electric
Commitment by CEO Jack Welch
Grown to be an integrated strategy for attaining extremely high levels of quality
4. 11/13/07 SJSU Bus. 142 - David Bentley 4 What is Six-Sigma?
5. 11/13/07 SJSU Bus. 142 - David Bentley 5 Percent Not Meeting Specifications +1S = 32%
+2S = 4.5%
+3S = 0.3%
+6S = 0.00034%

7. 11/13/07 SJSU Bus. 142 - David Bentley 7 Statistics - DPU Defect
Six Sigma: any mistake or error passed on to the customer ???
General view: any variation from specifications
DPU (defects per unit)
Number of defects per unit of work
Ex: 3 lost bags ÷ 8,000 customers
= .00375
8. 11/13/07 SJSU Bus. 142 - David Bentley 8 Statistics dpmo (defects per million opportunities) Process may have more than one opportunity for error (e.g., airline baggage)
dpmo = (DPU × 1,000,000) ÷
opportunities for error
Ex: (3 lost bags × 1,000,000) ÷ (8,000 customers × 1.6 average bags)
= 234.375
9. 11/13/07 SJSU Bus. 142 - David Bentley 9 Statistics dpmo (contd) May extend the concept to include higher level processes
E.g., may consider all opportunities for errors for a flight (from ticketing to baggage claim)
10. 11/13/07 SJSU Bus. 142 - David Bentley 10 Statistics - Off-Centering Represents a shift in the process mean
Impossible to always keep the process mean the same (this WOULD be perfection)
Does NOT represent a change in specifications
Control of shift within ą 1.5 s of the target mean keeps defects to a maximum of 3.4 per million
