Research showed that the most successful teams were made up of a diverse mix of behaviours; they had access to all nine Belbin Team Roles.
This doesn't mean that every team requires nine people! Most people will have two or three Team Roles that they are most comfortable with.
There are no good or bad Team Roles. Each Team Role has it's strengths and weaknesses, and each has equal importance. However, not all are required at the same time - it is important to first look at the team objectives, and work out which tasks need to be undertaken. Once this has been done, discussions can take place regarding which and when each Team Role behaviour should be utilised.
None of this is possible without an individual completing a Belbin Self-Perception Inventory and asking for feedback from their colleagues. The Belbin Report that is produced will help pin-point individual strengths to communicate and share with the rest of the team.
