What purpose could be served by teaching rudimentary technology basics to non-technical employees? What good does it do for HR or finance employees to understand what a transistor is? In short, one must accept pretty much on faith that knowing where your paycheck comes from is good for morale. If one accepts that employees deserve a layman’s explanation for financial results, it is not too great a stretch to conclude that they also deserve a layman’s explanation for the technology that is the basis for those financial results. There is also a benefit to the trainer, especially one who normally teaches only other engineers and assumes a high level of background knowledge in doing so. Occasionally examining our hidden assumptions is a healthy thing for anyone.
