In each of the following, name the term defined or answer the question. Answers are listed at the bottom.1. A Six Sigma process that is running at the center of its control limits would expect this defect rate.2. The variation that can be clearly identified and possibly managed.3. Variation is inherent in the process itself.4. If a process has a capability index of 1 and is running normally (centered on the mean), what percentage of the units would one expect to be defective?5. An alternative to viewing an item as simply good or bad due to it falling in or out of the tolerance range.6. Quality characteristics are classified as either conforming or not conforming to specification.
Why are adherents of quality management and continuous improvement opposed to the traditional perspective of quality control expressed in the use of acceptance sampling ?
Suppose that a quality characteristic is normally distributed with specifications at 100 ± 20. The process standard deviation is 6.(a) Suppose that the process mean is 100. What are the natural tolerance limits? Calculate Cp and Cpk and interpret these ratios. What fraction of parts do you expect to be defective?(b) Suppose that the process mean is 106. What are the natural tolerance limits? What is thefraction defective? Calculate Cp and Cpk and interpret these ratios.
