One of the many jobs I have had was at a plant that made stainless steel pipe and tube. The process was that we would buy large rolls of stainless steel, slit them to the proper sizes, then cold roll those into pipe. The edges of the roll would be welded together, then the now completed pipe was induction annealed so it would hold its shape.
We had a woman there who was in charge of QA. It was her job to test each batch of pipe to ensure that the pipe was properly manufactured. Once, the woman decertified an entire batch of pipe because the welds were faulty and had microscopic cracks in them. That batch had to go out the next day so we could meet the customer’s deadline. It was a couple of dozen tons of pipe.
Management fixed the problem by firing the QA department and shipping the pipe. Of course, the entire batch of pipe came back when the welds began to fail. Due to bad management, the company went out of business less than a year later.
I am telling you this story because there is a lesson there. One that will easily apply to the situation in this country with regards to our education. The Oregon governor recently decided that too many black students were failing tests in reading and math proficiency. To her, the obvious problem lies in the test, so the test was eliminated.
