Yes, it is. It is a well known field in hardware development, and generally treated as a sub field of manufacturing engineering. It deals with things like testing, sampling, statistics of yield, and process improvement. If you’ve ever done a DFMEA, an 8D report, a Five Whys review, a sampling quality analysis, or a process map, you’ve used tools produced by this discipline.
That’s what I’m trying to tell you and everyone else reading this.
Software, as a profession, collectively talks about quality with all of the rigor of joint passing English majors sharing their favorite sections of Zen and the Art of Motorcycle Maintenance.
Quality has a meaning and a definition and a field of study attached to it. Semiconductors and large scale consumer product manufacturing wouldn’t exist as we know it without this.
