I’m a Type-A personality with a sense of urgency to explain everything. Give me a little data, and I will use every statistical tool I can wrap around these rationalizations to help explain an observation. But here is something that I cannot explain: why do we tolerate such poor gages?
We should not comment on the quality of a process without accurate data, but we seem incapable of providing it. We are not much farther from the days in which we checked our oil one dipstick at a time.
