      What process targets (in terms of mean and standard deviation of the filling process) are needed for the filling machine to have a six-( capability? Answer: We need to center the process at the middle of the specs, i.e., at 400 gms. To yield six sigma quality the standard deviation must be (400-390)/6 = 1.67 gms. 88 Chapter 9. Chapter 9 89

      First Time Yield - FTY Rolled Throughput Yield – RTY. 1.5 Sigma Process Shift Explanation . By . Zack Swinney. iSixSigma recently released a process sigma calculator which allows the operator to input process opportunities and defects and easily calculate the process sigma to determine how close (or far) a process is from 6 sigma.

      Six Sigma A term coined by Motorola to express process capability in parts per million. A Six Sigma process generates a maximum defect probability of 3.4 parts per million (PPM) when the amount of process shifts and drifts are controlled over the long term to less than +1.5 standard deviations. Special Cause See Assignable Cause.
