Ralph H. Kilmann, Ph.D., is CEO of Kilmann Diagnostics (KD) in Newport Coast, California. In this capacity, he has created all of KD’s recorded online courses and assessment tools on conflict management, change management, expanding consciousness, and quantum transformation. Ralph’s online products are used by such high-profile organizations as Amazon, Bank of America, DuPont, Exxon Mobil, FedEx, GE, Google, Harvard University, JP Morgan Chase, Microsoft, NASA, Siemens, Twitter, the U.S. Army, and the World Health Organization.

Ralph earned both his B.S. in graphic arts management and M.S. in industrial administration from Carnegie Mellon University in 1970, and a Ph.D. degree in the behavioral sciences in management and social systems design from the University of California, Los Angeles, in 1972. After Ralph left UCLA, he immediately began his professional career as an Assistant Professor at the Katz School of Business, University of Pittsburgh. In 1991, the faculty awarded him the George H. Love Professorship of Organization and Management, which he held until 2002, when he relinquished his tenured faculty position. Instead of staying in Pittsburgh, Ralph moved to the West Coast, since he wanted to fulfill his California Dream, which led to the creation of Kilmann Diagnostics.

He has consulted for numerous corporations throughout the United States and Europe, including AT&T, IBM, Ford, General Electric, Lockheed, Olivetti, Philips, TRW, Wolseley, and Xerox. He has also consulted for numerous health-care, financial, and government organizations, including the U.S. Bureau of the Census and the Office of the U.S. President.

Ralph has published more than twenty books and one hundred articles. In 2021, he published his LEGACY BOOK, which integrates everything he has created during the past five decades of his professional life: Creating a Quantum Organization: The Whys & Hows of Implementing Eight Tracks to Long-Term Success. Ralph is also the coauthor of more than ten assessment tools, including the Thomas-Kilmann Conflict Mode Instrument (TKI).

In 2023, Ralph published his first book that focuses on the TKI assessment tool: Mastering the Thomas-Kilmann Instrument: Celebrating More Than 50 Years of Resolving All Kinds of Conflicts.

Ralph Kilmann’s Target Audience and Primary Mission for Mastering the Thomas-Kilmann Instrument (TKI)

Dr. Kilmann’s “TKI Book” is intended for the great variety of practitioners who are dedicated to helping people, families, communities, organizations, and nations resolve their most troublesome conflicts. Specifically, the relevant practitioners include trainers and facilitators; independent consultants; human resources executives; holistic change agents, executive and business coaches; mediators and ombudspersons; couple and family therapists; professors and students; international peace-builders; and project managers.

Dr. Kilmann’s book presents the theories and the methods for how to resolve all kinds of conflicts: intrapsychic (internal) conflicts, interpersonal conflicts, group and team conflicts, organizational conflicts, civil wars and international wars.

Here is the bottom-line question that Dr. Kilmann answers in his book: How can people resolve their conflicts in a manner that will satisfy everyone’s most important needs and concerns? Although an organization’s long-term success can never be guaranteed, especially in our increasingly fast-paced, diverse, interconnected global village, the probabilities are remarkably increased when all members are able to address their most important conflicts in the most productive and satisfying manner.

The TKI Book


This is the first book to integrate the most valid theories and methods for expertly using the Thomas-Kilmann Instrument for all kinds of conflicts. As I was assembling all the materials I’d ever created about the Thomas-Kilmann Instrument and conflict management (since the early 1970s when the TKI was first created), I knew I had to develop a meaningful sequence of chapters—starting with the basics of the TKI Conflict Model and the TKI assessment tool and then proceeding with how to USE that model and tool for resolving all kinds of interpersonal conflicts, team conflicts, organizational conflicts … all the way to facing the most devastating conflicts on this planet: civil wars and international wars.

At the start, I discuss the TKI Conflict Model, it’s two underlying dimensions, the five conflict-handling modes, and the three diagonal dimensions that enable a deep interpretation of your or anyone else’s TKI results. Then I cover the eight key attributes of a conflict situation (e.g., the level of stress, the level of trust, the relative importance of the issue to both parties, etc.), which determine when to choose-and how to use-each one of the five conflict modes: competing, collaborating, compromising, avoiding, and accommodating. Next, I demonstrate how to conduct an in-depth interpretation of six very different TKI Profiles. Afterwards, each person can then use their personalized TKI results to significantly improve their conflict-handling behavior. With that background, my book addresses some of the most challenging conflicts in our world today.

For example, I discuss one of the most novel and profound applications of the TKI Conflict Model and the TKI assessment tool: How you address your INNER conflicts plays a major role in how you address all your OUTER conflicts. In my experience, the focus of virtually all discussion in conflict management concerns the variety of OUTER conflicts that people face in life; yet we can utilize the same conceptual model and use the same assessment tool to address a person’s INNER conflicts, which include: Are you governed by your ego OR your soul? Is your ego and soul separate from (or fused with) your surrounding systems Have you resolved your primal relationships?

Lastly, I discuss how to all the prior material in the book can be used to resolve CIVIL WARS and INTERNATIONAL WARS.
