> I would imagine a higher up got very angry every time a batch failed. > After awhile you learn to just keep your head down. Many people don’t feel safe enough to push back. Or they stop questioning after awhile. Worked at a foundry where a metal lab tech was caught fudging the numbers for this exact reason. The floor manager would get angry at the tech for telling him the "wrong" mix of alloying elements to put in the melt after the main charge was molten. In reality, the manager should have been mad at the suppliers sending him shoddy alloying elements of wildly varying quality. Or he should have been mad at the metallurgist for not putting in the correct info w.r.t. the quality of the alloying elements.
