Power Index®

The Impact You Want
to Make?

The Diamond Power Index® (DPI) leadership assessment measures leadership efficacy using the framework of Power Intelligence®.

It is the only leadership assessment that looks specifically at the effective use of power—personal power and positional power—shining a light on the critical link between use of power and its impact on organizational outcomes and culture.

The DPI measures two facets of power—the leader’s assessment of their personal power and others’ assessment of their use of power along seven unique power competencies. The Power Profile® report integrates results into a comprehensive roadmap for development, with actionable insights and suggestions for improvement.




Join this 7-week email course to learn the 7 key behaviors for using power effectively. Each email introduces one of the behaviors, showing what it is, why it matters, how it plays out, and the concrete steps leaders—or anyone—can take to improve this critical behavior.

If you’re a leader, or you support leaders in your work, you’ll want to sign up for this free once-weekly email course to learn how to use power to foster healthy and inclusive organizational cultures.
