Ah, food! It just reminded me of this story.
I knew someone who worked in the What Went Wrong department of a major food processing company. WWW investigated problems like exploding cans, horrible off-tastes, or products that turned weird colors.
Let's say that one of the company's products was Peter Piper's Pecks of Pickled Peppers. My friend told me that WWW had figured out the manager turnover in the Peter Piper division. Almost exactly at 2-year intervals, WWW would be asked to figure out why the peppers were now turning black and slimy. Sure enough, a new manager had discovered that the pickling recipe called for a small amount of X. There did not seem to be any reason for including X, so the manager figured that a perfect way to look good with management was to cut costs by eliminating X. Alas, X was critical in preventing peppers from becoming black and slimy.
WWW was never able to figure out why this bit of wisdom was not imparted to incoming Peter Piper managers.
