I just went through it at my company part of a 5S, Six Sigma, Black Belt, Green Belt thing. It's suppose to tell what your tendencies are and then give you tools to recognize others and the best way to deal with them. It's a pretty accurate, at least for me, but it's not a "Universal This Is What You Are." It's more of a "this is your current comfort zone of personality" but it can change depending on the situation. It was kind of fun but I figure in a week I'll forget about it all.
