Storehouse co-founder and ex-Apple designer Mark Kawano:
I think the biggest misconception is this belief that the reason Apple products turn out to be designed better, and have a better user experience, or are sexier, or whatever . . . is that they have the best design team in the world, or the best process in the world […]
It’s actually the engineering culture, and the way the organization is structured to appreciate and support design. Everybody there is thinking about UX and design, not just the designers. And that’s what makes everything about the product so much better . . . much more than any individual designer or design team.
He shares some more insight into the design process at Apple.
