Question: 1. For a six sigma capable process, how many total standard deviations would fall within the specification limits? 2. Explain why TPY (throughput yield) is
1. For a six sigma capable process, how many total standard deviations would fall within the specification limits?
2. Explain why TPY (throughput yield) is the preferred and more appropriate measure of process quality as compared to the classic "yield" metric.
3. Identify (3) evidence/signals of nonrandom behavior that are used to determine if a process is in statistical control (i.e. stable).
4. Specifications for a bicycle derailleur are 6.000cm +/- .001 cm. The current manufacturing process produces parts with a mean of 6.0001cm with a std deviation of .0004. The population is normally distributed. Calculate the Cpk. Is the process capable (i.e. Cpk >=1.25). Show your work.
