The Belbin® Inventories and reports
Once the research was complete, Dr Belbin devised the Belbin Self-Perception Inventory (SPI) and Observer Assessment (OA), designed to measure an individual's Belbin Team Roles.
The SPI is designed to be completed by the individual, and the Observer Assessment, by colleagues.
Over the years, the inventories have been subject to rigorous statistical analysis to ensure that they measure Team Role behaviours as accurately as possible. More information on the reliability and validity of the Belbin inventories is provided below.
Inventories are completed online to produce a Belbin Individual report.
There is no sanctioned self-scoring inventory available. For more information, please see our copyright information.
