What would be the best approach to represent the baseline process capability with respect to the overall Turnaround Time for Stat tests, for all hours of the day? (Note: it is inadvisable to draw any conclusions about the capability of an unstable process, but in this case, we're not making any prediction about the future, we just want to characterize past performance in a way that is broadly understandable.) A Remove the outliers, then calculate the Ppk B Use a non-normal process capability calculation to determine the Ppk C Compare the mean cycle time to the target D Calculate the 3 Sigma Upper Limit, Adjusted for Skewness E Calculate the percentage of observations beyond the target time
