Japan used a lot of Deming’s theories, to significant success. I worked for a Japanese company.

In my case, the company produced absolutely top-shelf stuff, but even relatively mediocre companies did well, using Deming’s techniques. It required that everyone be on board, wrt the culture, though.

But I have found that a “good” engineer is one that takes their vocation seriously. They may not be that accomplished or skilled, but they have self-discipline, humility, and structure.

I’ve met quite a few highly-skilled “not-good” engineers, in my day. I’m embarrassed to say that I’ve hired some of them.
