 The Inventory assesses how an individual behaves in a team environment.The assessment includes 360-degree feedback from observers as well as the individual's own evaluation of their behaviour, and contrasts how they see their behaviour with how their colleagues do.Belbin himself asserts that the Team Roles are not equivalent to personality types, and that unlike the Myers-Briggs Type Indicator, which is a psychometric instrument used to sort people into one of 16 personality types, the Belbin Inventory scores people on how strongly they express behavioural traits from nine different Team Roles.
