Influence Style Indicator

About the Influence Style Indicator

The Influence Style Indicator (ISI) defines influence as “the interpersonal behaviours that we use to have a positive impact on another party’s choices.”


Using this definition, the Influence Style Indicator measures an individual’s preferred styles as they influence others. The assessment assesses the respondent’s dominant and under-utilised influencing styles, also how to identify others’ preferred styles.

  • Asserting: You advocate by debate, insisting your ideas are heard and challenging the ideas of others

  • Inspiring: You advocate by presenting a sense of shared purpose and exciting possibilities 

  • Bridging: You advocate by connecting, building relationships and coalitions

  • Negotiating: You advocate through comparisons, concessions and trade-offs to reach outcomes that satisfy your greater interest

  • Rationalising: You advocate by offering logic, rational reasons and data
