Well, that is the single largest expense we have. If we want to optimize anything in our discipline we should look at this part first. We talk often about how we build systems, but how often do you talk about how you spend the “figuring out” time? If we do not talk about it, it’s not explicit. If it’s not explicit, it does not get optimized.
In addition to the author’s suggested solution to this problem allow me to add: developer retention! Nobody has more to figure out in a system than the people who just joined the team. Cut down on that (via better compensation, workplace satisfaction, etc.) and you cut way down on that oh so expensive “figuring out” time.
