Maybe you were born with it. Or maybe it was learned.

Influence is a daily part of everyday work life, from resolving misunderstandings with colleagues to negotiating complex deals and leading project teams. And while there are several different styles of interpersonal influence, research shows that assertive behavior has the greatest impact on individual success and organizational performance. The good news is that influence is a learned skill. With the right training, some self-discovery, and a healthy dose of practice, people can develop their ability to be assertive.
