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.

How It Works

Individuals respond to 40 statements, choosing one of five options they believe to be most characteristic of their behavior. The assessment reveals scores in each of the four interpersonal influence styles as well as a dominant style. It takes approximately 20 minutes to complete and score. We recommend you allow up to an hour for the interpretation of results, debrief, and action planning.
You can expand the learning into a 2.5-hour workshop using the program outline and Microsoft PowerPoint presentation that's included with the facilitator guide. Trainer certification is not required to administer or facilitate the Interpersonal Influence Inventory.
