About IDI

The Interpersonal Dynamics Inventory

The Interpersonal Dynamics Inventory (IDI) is a multi-rater tool that brings multiple perceptions together to measure aspects of our behavior rather than our intent. The results grow our awareness about how our behavior impacts others, improve our ability to work with and influence others, and help us understand what motivates our own and others' interpersonal behavior.

The History of the IDI Tool

The Interpersonal Dynamics Inventory (IDI) was initially developed in the United States by Dr. Richard E. Zackrison, Ph. D. in 1977. Drawing on extensive research conducted by Drs. David Merrill and James Taylor about the relationship between human behavioral styles and managerial effectiveness, Zackrison produced a framework for gathering behavioral data that could then be categorized by the same social styles that Merrill and Taylor produced.

In 1980, Zackrison moved to Sweden to continue developing the Interpersonal Dynamics Inventory. His work resulted in the instrument as it exists today, which emphasizes the interpersonal tendencies of human nature while remaining sensitive to the varying behavioral norms of cultures around the world. Unlike industry tools like the Meyers-Briggs, the Interpersonal Dynamics Inventory draws on both self-perception and input from significant others in the workplace—for instance, co-workers, supervisors, and subordinates. The resulting feedback allows an individual to understand his or her social style and own managerial strengths and weaknesses.

Throughout the years, the IDI tool has been consistently tested and adjusted as needed to ensure its foundational approach can translate to modern users and practice. The IDI tool is now fully operational in a digital format while continuing to employ the groundbreaking outcomes of decades of behavioral-based research.

Relators

(Often Affiliative/Seldom Directive) Relators are those among us who are driven by connecting to others and making sure people are participating, supported and satisfied.

Motivators are perceived to be enthusiastic, exciting and absorbing, and enjoy interacting with other people, particularly if they are given the chance to be the center of attention.

(Seldom Affiliative/Often Directive) Producers are the task masters that move others towards a goal and make sure the path is clear. Producers are perceived to be independent, enterprising, ambitious and competitive. Producers put great emphasis on performance, particularly their own.
