If this meeting were a cup of coffee... radar charts for evaluation
I have given up using the evaluation technique in which you ask people, "If this meeting were a pair of shoes, what kind of shoes would they be? Roman Sandals? Pumps? Flippers?" Or, "If this workshop was a cup of coffee what kind of coffee would it be? Espresso? Turkish coffee? Soy or whole milk?" (I like that kind of thing, but I have found that not everyone does!)
But, we can borrow a tool used to evaluate coffee and other things to evaluate our work: the radar chart. (http://en.wikipedia.org/wiki/Radar_chart)
