The Diamond
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.

Here is what some of our users have to say:

“We have found the DPI a really valuable tool in holding deep and pragmatic coaching conversations that help illuminate blind spots and explore topics that may otherwise stay in the ‘too hard basket’ around how we lead.”


Head of People and Team Development, UK

“The Diamond Power Index is a unique assessment tool for management development. The comprehensive report detailing the results provides an educational roadmap for not only awareness, but levers to impact successful interactions and relationships.”


Senior Director, Global Employee Relations and EEO Compliance USA

“I’ve used many tools over my 20 years of consulting. The Diamond Power Index stands apart from the rest. Because it combines feedback from others across 7 unique power competencies with self-assessment on Personal Power metrics, it opens the door to entirely new coaching conversations. As a coach, that’s exactly what I want.”

Personality-based instruments are often used to build leadership capacity . Knowing your unique traits and characteristics provides clarity about your strengths, gaps, and unique leadership style. By offering ways to understand personal differences, they are useful for team development.
Competency-based 360s help build the business. They assess the skills and capacities needed for the leadership role, and for running the business. They identify strengths and skill gaps, and compare results against global or company benchmarks.
Assessments that measure potential help organizations build their leadership pipeline. They may measure IQ and cognitive skills, personality traits and characteristics, and even values and interests to establish culture fit and person-role fit.
Assessments that focus on impact help build culture. This is where the DPI sits. These assessments measure the impact leaders have on the performance of others and on the culture at large. They shine a light on the far reaching impact a leader has on the behavior of others and how it cascades throughout the company.

How does the Diamond Power Index® differ from other 360º leadership assessments?

Leadership is a journey through different stages of development. Each stage requires not only different skills, but increased self-understanding and insight necessary to transform to the next level.

As leaders rise in the ranks, it’s critical that they get feedback that helps them see their impact on the performance of others and on the culture at large. This is where the DPI sits.
