Evolution and Model

The Diamond Power Index® (DPI) is a scientifically valid instrument that has been normed by more than 500 leaders from 62 unique organizations, spanning 12 different countries

It measures the impact leaders have on those around them and how effectively they are able to inspire, empower, and achieve results.

The DPI® guides leaders on a journey of self-development, and provides actionable insights for motivating, influencing, and inspiring the people around them.

DPI®’s framework looks at three aspects of power:

  • Personal Power: The leader’s own sense of power and capacity to impact the world.
  • Power Perspective: A 360° assessment that profiles a leader’s effectiveness along the critical dimensions of power and authority.
  • Developmental Drive: Characteristics and capacities that support or hinder the process of personal and leadership development.

In the white paper, Julie Diamond Ph.D. discusses how power is used in an organization and how it has an outsized effect on the organization’s culture. But power use is a blind spot: even the most well-meaning leaders aren’t always aware of the impact they have on others. Why? Because power doesn’t only change you; it changes the people around you.
