So this blog entry is a blatant plug for a very funny man who knows his marketing and can see the absurd side of the brand onion. (What? An onion doesn't have sides?) I used one of his cartoons here and hope you have time to have a look at Tom Fishburne's site.
I love the Mission Statement cartoon and the ones about the fun you can have with focus groups as well as the brand positioning cartoon that introduces the splendid concept of a Brand Butterfly. And check out "The Tower of Eco Babel" if you're working on a sustainability project.
Most of all, I love this quote: "If a picture tells a thousand words, a cartoon tells a thousand boring Powerpoint slides."
