“There are only two barriers to running a usability study:
1. the fear that you can’t do it, and
2. the desire for perfection. ”
Those are Jakobs. Both are valid. But he also forgot the fear of laughing. And Desirion. At you. For testing such a piece of crap. That’s a real fear of mine whenever testing. (since I’m always testing MY prototype)
And a fear of possums. I loathe possums. Rats from the Ninth Pit of Hell.
