That's what the dictionary says, but there's so much more to mavericks, especially if you have to manage them. IT managers who have dealt with mavericks say they are easy to spot. They're nonconformists who challenge the status quo. They're passionate about their work; creative, curious and energetic; willing to take risks; unafraid to stand alone or fight for an unpopular position; evangelical in their passion for change; and at once insightful and annoying.

Mavericks provide essential reality checks. Because they may refuse to follow a process they consider stupid, mavericks might be described as complainers, irritants and dissidents. But smart managers recognize their value. "Mavericks help people think differently, and they do it by just showing up," says Richard Schroth, who directed strategic technology initiatives at various companies for nearly 30 years and is now CEO and president of Executive Insights Ltd. in Olney, Maryland.

"They're the ones that know the mousetrap will never be finished," says Andy Wihtol, president of Andrew Associates Executive Search in Lake Oswego, Oregon, and an officer of the Society for Information Management. He says that average employees are "potential energy," but mavericks are "kinetic energy" that just needs to be harnessed. "The maverick is not comfortable with the norm and is very comfortable influencing change," Wihtol says.

You'll find mavericks in every field, but some IT managers suspect that there are more per capita in technology than anywhere else. And they may be right, since IT attracts analytical thinkers who can spend their careers building and tinkering. If IT is a maverick magnet, that's good news. Mavericks keep an organization honest, and they're catalysts for change. But by their nature, they also challenge managers.

Tim McCracken, a former CIO who now leads the technology leadership practice at Tatum Partners LP, a consulting firm in Atlanta, describes a maverick he once supervised as "both frustrating and frustrated."
