You made it to the position of CIO because, in part, you excelled as a hotshot performer on the way up. Now that you're a senior manager, you'll need to effectively lead an entire department full of potential hotshots to ensure success. The very moment that you first step into a room as the "new boss" sends a clear message to your employees - either you "have it" or you don't. And that "it" is the ability to take command - whether it is taking charge of a room, or a crisis, or a great potential growth opportunity. In an article for the McKinsey Quarterly

Other times, there's a bit of smoke and mirrors involved. Here's more from Sutton - a professor of management science and engineering at Stanford, and author of the book "Good Boss, Bad Boss: How to Be the Best . . . and Learn from the Worst" (Business Plus/September 2010).
