The Thomas-Kilmann Conflict Mode Instrument (TKI) is a fast and powerful tool that can go beyond conflict management to support your team-building, leadership coaching, and retention goals. The research-supported TKI offers a practical way to initiate safe and constructive dialogue to resolve conflict. It offers an understanding of how different conflict-handling styles affect interpersonal and group dynamics thus empowering individuals to choose the appropriate style for any situation.

The TKI tool assesses an individual’s typical behaviour 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.
