The Origin of Six Sigma1979 The Real Problem At Motorola Is That Our Quality Stinks ! Art Sundry(Formerly Motorolas Senior Executive)
Tenfold Improvement Over A Five Year Period Robert Galvin (Formerly Motorolas President)
1980s Bill Smith discovered the correlation between market failures rate and manufacturing defects rate. At Government Electronics Group, under the leadership of Mikel Harry, experiments with problem solving through statistical analysis showed dramatic results. Mikel Harry began to formulate a methodology for applying statistical tools for problem solving. His work culminated in a paper titled The Strategic Vision for Accelerating Six Sigma Within Motorola.
1990 Robert Galvin asked Mikel Harry to start up and lead Motorolas Six Sigma Research Institute. The mission was to develop Six Sigma implementation strategies, deployment guidelines, and advanced statistical tools that would work in a variety of companies and industries.

Six Sigma BenefitsGE Capitals railcar-leasing business achieved 62% reduction in turnaround time at its repair shops. Customer who once found themselves able to talk with a GE Capital Mortgage associate only 76% of the time now have a 99% chance of success on the first try. GE Plastics added 300 million pounds of new capacity through rigorous Six Sigma process work. Citibanks Regional Cash Product Management Unit in Asia Pacific improved the defect rate of its fund transfer process to 4.95 sigma level.

What is Sigma? Sigma (Greek letter ) is a symbol for statistical unit of measurementcalled standard deviation that measure the variability of data from the mean. In Six Sigma program, Sigma is an index for measuring the capability of process to produce defect free products or services. A defect is any mistake that results in customer dissatisfaction.
The higher the sigma level, the less likely a process will producedefects. As sigma increases, costs go down, cycle time goes down, and customer satisfaction goes up.
Process VariationInput Process Output
All businesses are a system of interconnected processes. Variations exist in all processes. Variations in processes result in process outputs variability. Understanding and reducing process variability is the key to improving the capability of a process to produce defect free products or services.
Process Output VariabilityCycle time for taking X-ray at a hospital
Process Variability &Process CapabilityProcess Output Variability Customer Requirements Customer Requirements
Defects Less variability means less defects will be produced. Less defects means better capability in meeting customer requirements.

Is Three Sigma Performance Acceptable?Example: GE Plastics before Six Sigma implementation 95% compounded product first pass yield=>3 million pounds of rework week. 90% on-time delivery =>1 missed shipment every 30 minutes. 98% billing accuracy. => 1 billing error every 3 hours. 98% capacity utilization => 20 million pounds of lost opportunity. 95% meetings star on time(5%with a 10-minute delay) => 1,000 work-hours lost each day.
