Mark Parker’s office on Nike campus, is full of paraphernalia. It’s a visual overload when you first walk in. It’s not exactly the office you’d expect a top CEO to have, but when you consider that Parker started out as a designer for Nike over three decades ago, it makes a bit more sense. Parker is all about visual stimulation and inspiration. One of his mantras is “Be a Sponge.” And it’s obvious that he lives by it. He also lives by the idea that collaboration is key and that design is the foundation of any company’s success.
