Design process from a number of different disciplines: writing, shoe design, architecture, animation and filmmaking.
Chuck Lorre (creator of Two and a Half Men and Big Bang Theory) on the writing process for television:
"I came up, I was taught... you break a story, you have an outline and you send the writer off for 10 days, 2 weeks, to write the script and they bring it back and the executive producer throws it out. That's how television gets made."
"The rewriting process is generally a sustained argument with the guy who wrote the first draft and the executive producer. Everybody is miserable, everybody hates one another, "you're ruining my work!"... or you're secretly thinking, oh, they're making it better, "thats even worse!", I'm no good, I'm not worthy, I'm a fraud... either way you're not happy."

I've repeatedly stated that the biggest problems interactive agencies had during the 1.0 days wasn't with talent and people but the integration of all of those diverse talents and personality types. Even in leadership positions (and especially there at times) many people believed that their part of the process was THE most important part of the process.
The reason so little innovative digital work comes out of traditional advertising agencies is not a result of a lack in the development of capabilities, it's that they've never understood and embraced tech/geek culture. The people and sensibilities that live and create within the digital/interactive space were, and still are, seen as production people and not integrated into the "creative process". There are some great lessons to be learned on fostering creativity and managing multi-disciplinary processes from these two articles on Pixar.
