> In fact, management is full of numbers that a slightly-clever high school sophomore who’d paid attention in science classes could tell you are totally useless, because they were gathered all wrong. They mean nothing whatsoever. They’re just noise. The whole point of SPC is to separate signal from noise. Pointing out that some change that everyone is obsessing over is well within the expected range is useful, it can head-off knee jerk reactions to phantom issues.

"In the wild" is everything from wishful moronic overly technical to systems that worked 75 years ago still in place and no one knowing how or why it all continues to work. We've got a huge diversity of understanding, and thanks to a relatively stable society all kinds of inarticulate nonsense has been accepted by people as their reasonings for things that do not and could not work in a million years, but no one is going to tell them. So they continue in their belief. I think I was lucky to land in some seriously scientific groups that had personal grudges against emotional decision making, and they went overboard being analytical.
