摘要

Sometimes, like it seemed for a client's company, there are ghosts in the machines. On paper, everything seemed fine. The company tested every component and every supplier solemnly swore their hardware worked. And yet, the production line was freaking out unpredictably and often and the company was missing product ship dates. All the tests said everything was flawless - except it wasn't.
