Balanced Scorecard Software (Strategic Analysis, Management). The Belbin Team Role Inventory assesses how an individual behaves in a team environment. It is therefore a behavioural tool, subject to change, and not a psychometric instrument. The test includes 360-degree feedback from observers as well as the individual's own assessment of their behaviour, and contrasts how they see their behaviour versus how their colleagues do. Unlike the Myers-Briggs, which is conventionally used to sort people into one of 16 types by how clearly they express their preference for 4 dichotomous types of behaviour, the Belbin Inventory scores people on how strongly they express traits from 9 different Team Roles.
An individual may and often does exhibit strong tendencies towards multiple Roles. Belbin himself asserts that the Team Roles are not equivalent to personality types.
