Earlier quoted context omitted.
The problem with consistency is that if you're not already doing the right thing, you'll never do the right thing. Not even by accident.
I disagree. Even if you are doing the wrong thing consistently, one has a much greater chance of knowing what parameters can be tweaked to alter the outcome. Consistency is easier to monitor/log. It is easier to experiment. Without consistency, it is much more difficult to know which of your decisions changed the outcome, or was it just good or bad luck. Toyota and McDonald’s are successfully companies, but they are…
But in my experience striving for consistency means that before improving something you have to go and change everywhere that pattern appears in 400 different code bases going back 20 years (and all of the documentation across however many platforms). As a result nobody ever improves things.
As with all things YMMV.
