I worked on a relatively narrow part of a complex domain, I had an anki deck to keep track of the various acronyms and remember some of the weirder processes my systems participated in. Most of the questions were one of: - what does ABC stand for - describe process X - how process X differs from Y, and why - what is the role of system A in process Z - what is the shape of data that comes from A to B in process Ł This vastly reduced the number of times I got stumped with something during various high-level meetings (to the point that I routinely pointed out some false assumptions people made). It worked better for me than passive documentation. The domain was unusually complex though.
