Making decisions

I had a really interesting training at work recently.
It was about making decisions - how do people make them, what is the process and the methodology they use, why do they often delay making up their mind...

We got brief description of each person. The results of this exercise were very interesting and showed us how different approaches and priorities we have, what is the most important when making a choice and how we make our decisions...
