Missing from this list is that lots of the mentioned concepts are highly subjective. There is no generally agreed-upon standard of what documentation is "proper". Or what "clean" code is. Or what "competence" looks like. Or what a "scalable architecture" is. Etc etc. Most of these words are bent by whomever using them to make a point (or to boost their ego, sadly). Two people could easily work side-by-side and claim about the other that that person is incompetent and defend this position here on HN with some horrible-sounding anecdotes.
