Thomas–Kilmann conflict mode instrument

The Thomas–Kilmann conflict mode instrument helps people choose a response to conflict deliberately instead of relying on a habitual style. Kenneth Thomas and Ralph Kilmann define conflict as a situation in which two people’s concerns appear incompatible and show how different combinations of self-advocacy and concern for the other person produce different responses.

When to use it

• Use the model when you are directly involved in a disagreement or are helping other people resolve one.
• Use the framework without the formal questionnaire to diagnose a situation, or use the instrument’s 30 paired statements when a structured assessment of conflict preferences is useful.

Origins

Kenneth W. Thomas and Ralph H. Kilmann developed the instrument at the University of Pittsburgh during the nineteen seventies. They adapted an earlier two-dimensional managerial grid associated with Robert Blake and Jane Mouton, using assertiveness and cooperativeness as the central axes. The paired-choice design was intended to reduce the tendency to select whichever response sounded most socially desirable. Their central conclusion remains important: each mode can be constructive in the right circumstances, and none is best in every conflict.

What it is

The model maps conflict behaviour along two dimensions. Assertiveness is the extent to which you try to satisfy your own concerns; cooperativeness is the extent to which you try to satisfy the other person’s concerns. Their intersection produces five modes:

Avoiding:

low assertiveness and low cooperativeness; neither side’s concerns are actively pursued.

Accommodating:

low assertiveness and high cooperativeness; you give priority to the other person’s concerns.

Compromising:

moderate assertiveness and cooperativeness; each party gives up something to reach a workable middle position.

Competing:

high assertiveness and low cooperativeness; you pursue your position at the other party’s expense.

Collaborating:

high assertiveness and high cooperativeness; both parties work to satisfy the underlying concerns of each side.

The framework is descriptive, not a ranking. A preferred mode can be useful, but overusing it creates predictable blind spots. Effective conflict management depends on matching the response to the stakes, time available, relationship and possibility of an integrative solution.
