Card sorting
Or “My customers can’t find anything on my site!”
A very tricky problem in web design is how to organise the information on the site into categories. Card sorting solves this problem in a way that’s really pretty obvious.
You write out the items you’re going to have on the site on cards (assume for a moment we’re just talking about a bunch of simple documents you want to publish). Then you take that stack of cards and ask a customer to group them for you. Take a note of what they do, then go see another customer and ask them. Do this with a few customers, the client and maybe some other people and then look what consensus arises.
Frickin’ obvious. Gold dust. Thank you DoS.
