- A process has upper and lower tolerance limits of 5.80 and 5.00, respectively. If the customer requires a demonstrated Cpof 2.0, what must the process capability (standard deviation) be? If both Cpuand Cplmust also be 2.0, determine the mean and standard deviation of the process, assuming a normal distribution of output. (For this problem, assume the standard deviation is the same as what you calculated in the first part of the problem when you are asked to compute the mean for Cpu and Cpl in the second part of the problem. The answers actually come out to be the same number for both means).

Vetro has a customer who requires glass cut to a lower specification of 4.96 cm and an upper specification of 5.04 cm. Vetro's process averages 5 cm, but does have some variability. specifically, the standard deviation = 0.01 cm. What is Vetro's capability index for this customer? (Round to two decimal places)

A key joint in a precision machining process has a lower specification limit of a width of 0.99 mm and an upper specification limit of 1.01 mm. The standard deviation is 0.005 mm and the mean is 1 mm. The company wants to reduce its defect probability and operate a "Six Sigma process." To what level would this company have to reduce the standard deviation in the process to meet this target? Note: A "Six Sigma process" has a process...

1.)Ready Care is currently using SPC as a means for investigating its process. However, they want to determine if they are currently aligned with customer expectations. The marketing team has determined that customers expect some sort of a wait and are not likely to complain if the wait does not exceed 35 minutes. Operations has determined that the process mean is 25.25 and the standard deviation of the process is 2.5. Knowing this, what is the capability ratio (Cp) for...

As part of the process for improving the quality of their cars, Toyota engineers have identified a potential improvement to the process that makes a washer that is used in the accelerator assembly. The tolerances on the thickness of the washer are fairly large since the fit can be loose, but if it does happen to get too large, it can cause the accelerator to bind and create a potential problem for the driver. (Note: This part of the case...
