The science behind TeamSight

TeamSight—formerly known as Style of Influence—was developed as a behavioral assessment focused on team performance. In the early 80's, Douglas Wilson, PhD, was teaching Organizational Behavior at the USC Graduate School of Business and working with Toyota Motor Company's heads of HR and Strategic Development for North America to improve their leadership practices. Gene Getz, PhD, a former professor of Dr. Wilson's, had built a successful career implementing behavioral principles in both educational and religious institutions. They both championed the critical importance of productive team interactions that resulted in higher performance, and began to work together on a tool to assist teams in these areas.

At that time, most tools were based on identifying personal characteristics and were more descriptive by design. These were helpful, but Wilson and Getz believed a predictive tool for team interactions could prove even more useful. Their goal was to develop an assessment with exceptional internal consistency—one that would help individuals and teams perform at a higher level by recognizing their default behaviors and gaining awareness of how those behaviors influence themselves and others.

The empirical research behind TeamSight identified four highly consistent activities that impact team performance. Based on this research, the TeamSight assessment analyzes 84 items that identify how people naturally behave within the four areas of team performance, and presents actionable, objective feedback that isn't subject to interpretation.The results demonstrate an excellent internal consistency of reliability with a high degree of construct validity. The results from Exploratory Factor Analysis (EFA), Multi-Trait Multi-Method (MTMM) Matrix, and Confirmatory Factor Analysis (CFA), all strongly support the conclusion that TeamSight demonstrates excellent validity.
