Conflict can negatively affect productivity, decision making and retention. By resolving conflicts more effectively, you can strengthen your organisation and improve results. Make conflict management a core competency and create a satisfying and productive work environment throughout your enterprise.

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® assesses an individual’s behaviour in conflict situations and describes it along two dimensions: assertiveness and cooperativeness. The instrument provides detailed information about how that individual can use the five different modes, or styles – competing, collaborating, compromising, avoiding and accommodating – effectively. The TKI® model demonstrates that these different behaviours are neither good nor bad but simply different ways of dealing with conflict. This research-backed instrument offers a practical way to initiate safe and calm, yet purposeful dialogue, to resolve or manage conflict.

How can you use the Thomas-Kilman Conflict Mode Instrument?

Your organisation can use the TKI® as the foundation for conflict literacy – for developing a common language that helps people think and communicate clearly about conflict and how to manage it through the opportunities provided for accepting differing viewpoints, enhancing communication and improving productivity, team cohesion and retention.
