(or how American Apparel took over the world)
In our early classes, we look at Gestalt principles and learn that people are coded to be a bit lazy — that we tend to see things in groups, lines and structured arrangements... and even if they're not truly there, we kind of make them up simply to put our minds at ease. As communication designers, knowing these things helps us connect to our audiences more effectively. The same principle helps movie makers make more enjoyable films. It helps chefs make more interesting dishes.
When we look at brands, we can also look at these same tendencies. We can look at the sentiments of stability, trust, and comfort that these ideas bring to our minds... These are things that brands generally strive to achieve.

[Speaking of uncomfortable: When your critically acclaimed (and awesome) show is canceled, and all that's left are re-runs and bottles of cleaner on the discount rack...]
IN THE CLASSROOM
In GR604: The Nature of Identity, the challenge for students is to re-discover the soul of a dead, dying or defunct brand. The soul is not what a brand makes, but what it stands for.
Avon isn't about make-up, it's about women and opportunities. The soul of Mary Kay is similar, but a bit different, a bit more business-focused — and with a pick Cadillac — a lot more demonstrative. Pan Am is about cultural exchange. Maxtor is about preserving information and memories. Tupperware is about organizing the precious things in your life.
After choosing their brand and doing a lot of research, students are then challenged to envision where else their chosen brand might be able to take an offering like this. If Mary Kay was about opening doors to business opportunities for women, in 1963, that meant (to them) selling make-up door to door. What could that mean in today's context? What kind of service could they offer? What kind of educational offerings or co-branding opportunities could exist? This obviously goes far beyond the logo. This is also why this class lives at the graduate level. It's a lot of fun and yields some amazing projects. Our students can not only make pretty things, but know how things work — and most importantly why they work.
However, in the knowing of how and why, the idea of structured thinking comes into play... or as I've begun to call it in class: Diagrammatical thinking.
I often say:
"If you can't draw it, you probably can't really explain it."
