Four decades of research into how people actually work together.
IDI Profiling AB is the Swedish company behind the Interpersonal Dynamics Inventory, a psychometric tool used by thousands of organizations worldwide to develop the collaboration skills that drive real performance. IDI is certified by DNV according to the EFPA test review model.
What we believe about people and development
We focus on what you do, not who you are
IDI measures observable behaviour in context, not personality traits. Development is about expanding your repertoire, not changing who you are.
Context shapes everything
The same behaviour can be constructive in one situation and counterproductive in another. IDI always accounts for context and never applies static labels.
The gap is the growth
The difference between how you see yourself and how others experience you is where all meaningful development begins.
The foundation
Born from Dr Richard Zackrison's 1977 research at the University of Minnesota, the first version of IDI is applied in 1979 in the Swedish Armed Forces together with Dr Anders Risling. During the 1980s, IDI is part of Dr Zackrison's consulting firm Effectiveness Consultants and grows steadily in Sweden. By the end of the decade, about 25 facilitators have together delivered 25,000 profiles and a foundation for a Swedish norm has been created.
The people who built and lead IDI
From academic research to a global platform, built by people who believe in the power of collaboration.
In 1977, at the University of Minnesota, he developed the framework that would become IDI, a scientifically grounded approach to measuring how people collaborate in real work settings.
With roots in IDI dating back to 1990, he has shaped the methodology for over three decades. Appointed Head of Development in 2002, he founded IDI Profiling AB in 2014, driving the modernization of the platform and expanding its reach across languages and markets.
Aram has been central to IDI’s development since 2015, shaping both the platform and its theoretical foundation. In 2024, he became CEO and the third generation leader of IDI, advancing the platform toward a fully integrated environment for profiling, personalized coaching, learning, and progress tracking.
Leadership expert, educator, and researcher in organizational communication, and the son of Dr Richard Zackrison. A continuing lecturer at the University of California, Santa Barbara, he brings over 30 years of experience as a manager, entrepreneur, and consultant. His work focuses on leadership, team dynamics, and how people are experienced by others in organizations.
