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.

Successful institutions almost always develop strong cultures that reinforce those elements that make the institution great. They reflect the environment from which they emerged. When that environment shifts,it is very hard for the culture to change. In fact, it becomes an enormous impediment to the institution’s ability to adapt.

This is doubly true when a company is the creation of a visionary leader. A company’s initial culture is usually determined by its founder’s mindset—that person’s values, beliefs, preferences, and also idiosyncrasies. It’s been said that every institution is nothing but the extended shadow of one person.

Nothing can stop a cultural transformation quicker than a CEO who permits a high-level executive—even a very successful one—to disregard the new behavior model.

There are fundamentals that characterize successful enterprises and successful executives.

• They are focused.

• They are superb at execution.

• They abound with personal leadership.

Continuing to drive change while building on the best (and only the best) of the past is the ultimate description of the job of Chief Executive Officer, International Business Machines Corporation.
