When facing persistent, resistant challenges, leaders often surrender to poor results or invest in change efforts that waste time and resources. And yet it's possible to influence behavior with surprisingly predictable success. For the past thirty years, we've studied leaders with a proven ability to influence rapid, profound, and sustainable change. And here's what we know: human behavior is grounded in six sources of influence. Effective leaders know how to leverage and apply these sources of influence to solve everyday leadership challenges. Crucial Influence® teaches leadership skills that are essential to leaders at every level. Drawing on five decades of social science research and work with successful leaders around the world, the Crucial Influence Model reveals why people do what they do and how all leaders -- from aspiring leaders to top executives -- can influence others for lasting results. Crucial Influence is an engaging classroom course rich with group discussion, real-time practice, and group support, coaching, and personal reflection to maximize skill transference.
