Thomas Kilmann Conflict Model

The TKI (Thomas-Kilmann Conflict Mode Instrument) is fast and accessible, delivering insight, empowerment and resolution to anyone involved in conflict. By identifying alternative conflict styles, it helps people reframe and defuse conflict, creating more productive results.


TKI and Conflict Resolution

The TKI questionnaire identifies five distinct conflict styles and provides people with conflict-management solutions. By helping individuals understand their default approach in conflict, it encourages the exploration of alternative ways to handle different situations. And although it’s sophisticated, you don’t need to be an expert in conflict resolution theories to use it.

  • Assesses an individual’s typical behaviour in conflict situations.
  • Identifies five different conflict-handling modes, or styles.
  • On-line and easy to understand (30 items, takes just 15 minutes).
  • No certification required to use.
  • Helps individuals review interpersonal styles in challenging situations.
  • Facilitates learning to use five practical, situation-specific styles for dealing with conflict effectively.
  • Quick to implement and complete and provides results for discussion.
  • Rapid deployment to support independent or supported learning.


Competing is assertive and uncooperative - a power-oriented mode.  When competing, an individual pursues his or her own concerns at the other person's expense, using whatever powers seem appropriate to win his or her position.


Accommodating is unassertive and cooperative - the opposite of competing.  When accommodating, an individual neglects his or her own concern to satisfy the concerns of the other person; there is an element of self-sacrifice in this mode.


Avoiding is unassertive and uncooperative.  When avoiding, an individual does not immediately pursue his or her own concerns or those of the other person.  He or she does not address conflict.


Collaborating is both assertive and cooperative - the opposite of avoiding.  When collaborating, an individual attempts to work with the other person to find a solution that fully satisfies the concerns of both.  It involves digging into an issue to identify the underlying concerns of the two individuals and to find an alternative that meets both sets of concerns.


Compromising is intermediate in both assertiveness and cooperative.  When compromising, the objective is to find an expedient, mutually acceptable solution that partially satisfies both parties.  Compromising falls on a middle ground between competing and accommodating, giving up more than competing but less than accommodating.
