Embracing Conflict for Positive Change
Celebrating 50 years of the Thomas-Kilmann Conflict Mode Instrument (TKI®)
TKI celebrates 50 years



Welcome to the 50th anniversary of the TKI® assessment!

To celebrate 50 years of the assessment helping people around the world understand and manage conflict, we'll be sharing new resources throughout the year so you can better generate positive outcomes from conflict.

Whether you’re an experienced TKI practitioner or someone completely new to the assessment, you’ll find something to support your journey into successful conflict management. Watch this page as we make regular updates.


Why the TKI assessment?

36% of people say they deal with conflict often, very often, or all the time.

22% of people say their managers handle conflict poorly or very poorly. 4.3 hours are spent dealing with conflict every week by those who have to manage it.*

The TKI assessment celebrates its 50th birthday in 2024. But why is it so popular?

  • Its five different approaches to conflict give people a practical, accessible framework
  • It helps people understand both their own and other people’s approaches to conflict
  •  The assessment insights enhance leaders’ conflict management skills and ability to reconcile differences
