FIRO-B stands for Fundamental Interpersonal Relations Orientation - Behavior. The FIRO-B assessment was created in the 1950’s by Will Schulz to predict how members of the military would interact. Learning about needs has been important for intact or cross-function teams because it helps members to understand what each member of the team personally needs. The assessment measures Wanted and Expressed Inclusion, Control, and Affection. It is helpful to be aware of your own needs and the needs of your team members in order to successfully collaborate.
