WebPp is a measure of the overall capability of the process. Pp is a ratio that compares two values: The specification spread (USL – LSL) The spread of the process (the 6-σ variation) based on the overall standard deviation. Pp evaluates overall capability based on the variation in the process, but not on its location. WebThe process is centered, but not capable. Question 8 (1 point) Use the following example for questions 8, 9 & 10: A customer has asked for process capability on a particular process. The control charts, created with a sample size of n = 5, in place show that the centerline (XDB) is 0.50349 with a range of 0.00014.
