So far, what we do is simply take a large print out of the current feature we are working on and stick it on the wall. As brainstorming sessions and discussions happen about the feature, notes, scribbles and soon enough the printout needs to be updated with a new one as changes need to be made.
What's the best way to maintain updated user flow without having to make a new printout every time something in it changes? i'm thinking of a more modular approach as separate printouts per screen or stickers for each UI element. but that might be too granular.
What would be the best solution for this, and are there any best practices for this already?
