Consistently part of the conversations of the most valuable brand names in the world, Nike continues to enjoy a massive level success behind the work of its innovative team and CEO Mark Parker. From 2006 when he took over, Parker has managed to grow Nike’s market cap from $16.39 billion USD to an incredible $86.2 USD occupying a whopping 48% of the American athletic footwear market. To put this number into perspective, its chief rival adidas only owns 9%. Check out the excerpt below from Fortune’s interview with Nike founder Phil Knight discussing Parker’s role and success. The full read is available here.

In the video above, Fortune’s Nicholas Varchaver talks about the leaders on the Business Person of The Year List.

Parker is something of an oddity in a world of big-ego, headline-grabbing CEOs. Introverts, after all, aren’t the norm in the executive suite. But people like Parker and Apple’s Tim Cook AAPL -0.24% are showing that reserved types can deliver. Parker’s meticulous approach to product development, known as “design thinking,” is all the rage, thanks to the acclaim of Apple’s products under its famed designer Jony Ive. Parker remains committed to his original craft: He still noodles on two limited-run sneaker lines with famed Nike designer Tinker Hatfield, one of them with Nike spokes-icon Michael Jordan and the other with Japanese stylemaker Hiroshi Fujiwara.

Nike’s performance, like a seasoned champion that continues to steamroll the competition, has prompted Fortune to name Parker its Businessperson of the Year for 2015. Given that students of management are always looking for role models, it’s also a good excuse to investigate what makes Parker tick. After all, he is the rare successor of a celebrated founder who has taken his company to new heights. It is time, as Phil Knight tersely observed, to discover how Mark Parker does it.
