Thomas-Kilmann Conflict Mode Instrument®

The Thomas-Kilmann Conflict Mode Instrument (TKI®) tool is the world’s best-selling tool for helping people understand how different conflict-handling styles affect interpersonal and group dynamics—and for empowering them to choose the appropriate style for any situation.

The TKI tool assesses an individual’s typical behavior in conflict situations and describes it along two dimensions: assertiveness and cooperativeness. It provides detailed information about how that individual can effectively use five different conflict-handling modes, or styles.
