Walt Disney was a visionary, an accomplished businessman, and a creative mind that set the imagination free. And he did that not by letting every whim and fancy go wild, but by filtering ideas through a process to weed out the mediocre from the iconic.

The critic asks the tough questions and gives a strength test to the idea. He is adept at finding weaknesses and question the premises and assumptions.

Taking the free-wheeling imaginations, the realist evaluates the feasibility, practicality, and achievability of the ideas. He can also organize, simplify or clarify the idea at this stage.

To generate Ideas, a dreamer is allowed to provide ideas, big or small, weird, wild or charming, without any rules.  He does not have to worry about the details on 'HOW' or the costs of the idea.
