Moving from static design tools to prototypes in code has helped systems-level design work, because you cannot easily grasp the many combinations of states until you have something in some form of code.

doing that kind of work in like a static environment detached from the code was always way harder than it probably needed to be because you're think trying to think through like a ton of different combinations of states that are just hard to gro until you actually get something in some form of code to be able to understand whether your your idea even makes any sense at all
