If you're building for digital, for a place where you can't possibly be present to guide or to answer questions, I think it's vital you have someone who can review your work. Same for instruction manuals, secret ballots and road signs.
Not to make suggestions to make it better (what do they know?) but to share their confusions.
I don't think that's a phrase, but it should be. Share your confusions is a way of asking someone to dissect your work and point out what's not totally clear.
