Construction and Selection of Six Sigma Quick Switching Sampling System: Sample Size Tightening

D. Senthilkumar, B. Esha Raffie

Six Sigma at many organizations simply means a measure of quality that strives for near perfection. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects in any process, from manufacturing to transactional and from product to service. The statistical representation of Six Sigma describes quantitatively how a process is performing. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. A Six Sigma defect is defined as anything outside of customer specifications. A Six Sigma opportunity is then the total quantity of chances for a defect. In this article, desining of Six Sigma Quick Switching Variables Sampling System [SSQSVSS(nN,nT;k)] indexed by Six Sigma Quality Level's is presented. Procedures are indicated and tables are constructed for designing the system indexed by six sigma quality levels, viz., six sigma acceptable quality level (SSAQL) and six sigma limiting quality level (SSLQL).
