I came to see, in my time at IBM, that culture isn’t just one aspect of the game—it is the game. In the end, an organization is nothing more than the collective capacity of its people to create value. Vision, strategy, marketing, financial management—any management system, in fact—can set you on the right path and can carry you for a while. But no enterprise—whether in business, government, education, health care, or any area of human endeavor—will succeed over the long haul if those elements aren’t part of its DNA.

Culture isn’t just one aspect of the game - it is the game,” Gerstner says. “In the end, an organization is nothing more than the collective capacity of its people to create value. Vision, strategy, marketing, financial management - any management system, in fact - can set you on the right path and can carry you for a while. But no enterprise - whether in business, government, education, health care, or any area of human endeavor - will succeed over the long haul if those elements aren’t parts of its DNA.”

Chris Lofgren, chief executive of Schneider National, the large transportation and logistics company believes that “culture is a foundation upon which you build your long-term strategy. If you build a strategy that isn’t consistent with the culture, it isn’t going to work.

But it's not just management that gets it. The conviction that culture is key is embraced throughout the ranks at Zappos. It's so central to the company's belief system, in fact, that the company publishes the Zappos Culture Book, which is updated regularly and contains hundreds of unscripted comments and essays written by Zappos employees and vendors about the company's culture, why it matters, and how it affects what they do every day. It was conceived as a training tool for new hires and partners, but consumption of the book has gone way beyond that internal circle. Ringing in at 348 pages in the 2009 edition, it's a moving and persuasive testament to the power of employee engagement ("happiness" in Zappos-speak), and the role of culture in eliciting it. We recommend buying it and just paging through.

The quote that moved us most was from Ryan A.: "At my last job I was afraid to be anything: right, wrong, smarter, dumber ... At Zappos being yourself is the best thing you can do." Perhaps the cultural feature we observe most often is unproductive fear, fear of looking bad or doing something wrong. If organizations did nothing else but address that part of their environment, we're confident that the creativity and engagement of their people would have a real chance of being unleashed. Human beings are not at their best in a defensive, self-distracted crouch.
