That's a good way of looking at domain knowledge "one layer up". I'm have been terrible at this in the past and I have been making an effort to improve. Business knowledge seems to provide the most leverage, especially in fields like finance.

My problem is I find the knowing the lower level stuf way way more interesting. Heck I'm doing a udemy course on network programming which arguably won't help my career, I just have a secret shame about not really knowing networking. (Plus it's really interesting)
