2 TKIs 

Do you manage conflict differently
when you are inside versus outside your
group or organization?

Take the Thomas-Kilmann Instrument (TKI assessment) from the person who co-created it: Dr. Ralph H. Kilmann. Ralph’s e-learning platform offers all his research, online courses, and TKI certifications.

Why take two Assessments?

As described in our recorded online course, GROUP Training in Conflict Management, there are several benefits for taking TWO separate TKI assessments, each with modified instructions: (1) how you manage differences INSIDE your group and (2) how you manage differences OUTSIDE your group (across all other settings in your life).

By taking these two modified TKI assessments, you will learn how the leader, the other members, the culture, and the reward system might be unduly influencing how conflict is being managed in your group—which has not led to satisfactory outcomes for you, the group as a whole, and other key stakeholders. But once you (and your group members) receive the two TKI Reports from those two modified TKI assessments, members will be able to discuss which conflict modes are most needed for success INSIDE their group, while they also realize which conflict modes they’re already using effectively OUTSIDE their group. It will then be much easier for members to significantly improve their group’s conflict-handling behavior, which includes redesigning and aligning their surrounding systems so they’ll be able to use all five modes INSIDE their group—as the situation requires.

THE MOST KNOWLEDGEABLE EXPERT AT YOUR DISPOSAL: Dr. Ralph Kilmann is the co-author of the TKI: If you have any questions about how to administer the assessment or interpret your results, you won't be able to find another person who has more TKI knowledge and experience.

LEARN ALL ABOUT YOUR CONFLICT BEHAVIOR: The TKI is a self-report assessment that allows you to discover whether you might be overusing (a high score) or underusing (a low score) one or more of these five conflict-handling modes: competing, collaborating, compromising, avoiding, and accommodating.

COMPARE YOUR RESULTS TO THOUSANDS OF OTHERS: To determine which of your TKI mode scores are high or low, your results are compared to a. U.S. research sample of 8,000 men and women who were drawn from a pool of 59,000 TKI respondents in order to mirror the demographic distribution of the U.S. population. A subsequent cross-cultural research sample of 6,000 men and women from 16 different countries revealed only minor variations from the U.S. norms. These rather surprising results demonstrate that the TKI is measuring an aspect of conflict-handling behavior that is fairly consistent across different countries and cultures.

THE TKI IS AMAZINGLY ACCURATE: One reason that TKI results have such cross-cultural consistency is because the assessment was purposely designed to minimize the “social desirability response bias” (which is the natural tendency for people in all societies to respond to test items in order to look good to themselves or to others). Consequently, TKI results provide an accurate picture—across the globe—of how people actually behave in conflict situations.

MODIFYING THE TKI INSTRUCTIONS OFTEN LEADS TO EVEN GREATER ACCURACY IN RESULTS: For the first TKI assessment, respondents are instructed to consider only how conflict is managed in their particular group—in contrast to the standard instructions that asks them to consider all situations in one bundle. With modified instructions, therefore, the results for the group will not be diluted by how conflict is being managed in other situations.

LEARNING HOW ORGANIZATIONAL SYSTEMS AFFECT CONFLICT-HANDLING BEHAVIOR IS AN EYE-OPENER FOR ANY GROUP: For the second TKI assessment, respondents are instructed to consider how conflict is being managed outside their group. With these modified instructions, it’s now possible to examine the differences between conflict management inside versus outside the group, which is primarily shaped by the behavior and systems that can dominate group members: the leaders, the culture, and the reward system, to name a few.


Taking 2 TKIs per person (the first TKI for INSIDE the group and the second TKI for OUTSIDE the group) allows respondents to discover the impact of their leader, their culture, the reward system, and the key attributes of their unique situation on the group’s conflict-handling behavior. Taking 2 TKIs per person is highly relevant to these OCCUPATIONAL IDENTITIES:

Here are the TKI instructions for INSIDE/OUTSIDE. The words that can be changed have been set in bold.

INSIDE your group, how do you usually respond when you find your wishes differing from those of another group member? For each of the 30 pairs of statements below, select the letter (“A” or “B”) that best characterizes your behavior in your group.

OUTSIDE your group (across all other settings in your life), how do you usually respond when you find your wishes differing from those of another person? For each of the 30 pairs of statements below, select the letter (“A” or “B”) that best characterizes your typical behavior in these other settings.

Please let us know if you would like to change the focus of these instructions to: INSIDE/OUTSIDE your organization, your department; your school, the workplace… or whatever suits you. If you prefer that your participants respond to their TKIs with a different focus for INSIDE/OUTSIDE, we will place YOUR instructions in the emails that we send to your participants. But other than the INSIDE/OUTSIDE focus, we do not change any other aspect of the TKI instructions, since the rest of those instructions are essential for maintaining the validity of the TKI assessment process.

After you complete your checkout, please download The KD_Spreadsheet for Creating Group Accounts and follow the instructions. If you are buying a pair of TKIs for another person, fill out the spreadsheet for just that one person.

If you’ll be conducting an educational program for several members and you want to make use of their two TKI results before that meeting, ask them to send you a copy of their two personalized reports as soon as they have downloaded them.
