You all probably know these kind of (ux) guidelines as listed in the post of Justin Misfud here: http://usabilitygeek.com/official-usability-user-experience-user-interface-guidelines-from-companies/
my questions are:
do you also have these kind of guidelines in your company or that you follow for yourself as a freelancer?
If yes, how do you guarantee and systematically validate that all guidelines are always respected in your work?
