What does the TKI® assessment measure?
TKI® helps you understand your preferred approaches to handling conflicts. The asessment tool identifies five distinct conflict-handling modes, each defined by two key dimensions: assertiveness – the degree to which you seek to satisfy your own concerns – and cooperativeness – the extent to which you seek to satisfy the other person’s concerns.
These dimensions form the framework for recognising and reflecting on your responses to conflicts in various situations.
