I'm running out of people to do it with, but I love taking someone in the company who has never used, read about, or even seen a program and setting aside some time and just handing it to them and saying "do x".
It's such a massive help in finding what can be confusing, what requires industry knowledge, what is easy for a developer vs a user, etc... It's so often that we as developers take some knowledge for granted, and helping the user either get that knowledge, or not need it is monumentally helpful.
Sadly, I've found that once they do that, they are "tainted" and can't really do it again as well with that product, so it's something I try to do as late in the process as possible. But it has been what prompted me to throw out an entire redesign for a screen and start over very late in the process, and to good effect.
I'm seriously afraid our usability will suffer when we run out of people to do this with.
-I do this from time to time to test one-off service/support docs prior to shipping them off to my customers.
(I work in the marine industry; when a customer has a problem, he's often way out on the high seas, outside of even helicopter range - so, effectively, if whatever issue he's facing cannot be solved with what he's already got on board and some detailed instructions, he's SOL.)
After breaking down the solution (hopefully, we're able to isolate the problem!), I bring all the required hardware, software, scripts and my first draft for the solution document to someone Not Into Automation & Control(tm) - say, the cafeteria or cleaning staff and ask them to work their way through it.
It never ceases to amaze me how many things we just take for granted after working in a field for a few years. ("Oh, but surely it is self-evident that..." "F--k no, it isn't!")
Result: Someone not at all involved in the day-to-day management of our products feel a much stronger attachment to the company and what we do to stay in existence; a customer gets a procedure which is so detailed, they can have anyone do it; I get to sleep well as I know the tasks sent offshore are as detailed and correct as I can possibly make them - and everybody is better off. At least I like to think so.
