For more than 50 years, the Fundamental Interpersonal Relations Orientation™ (FIRO®) approach has helped people understand their interpersonal needs and how those needs influence their communication styles and behaviour – thereby improving their personal relationships and professional performance. The FIRO® instrument address the core of personality – people’s underlying needs – and precisely identify sources of tension in relationships

The FIRO® assessment is based on social need theory: all living things seek equilibrium between their basic needs and getting those needs met. They address, gather, and present critical insights around these fundamental areas: how you tend to behave toward other and how you want others to behave toward you. Use this instrument to cultivate highly effective teams by helping team members discover how their needs for participation, influence and closeness form their team’s success.
