Individuals may purchase the book (1st and 2nd editions) and complete the SPI for their own personal development, but any copying or wider usage is an infringement of copyright. To clarify our position, we own the copyright and do not allow this questionnaire to be reproduced in any form. In particular, the use of the self-scoring paper Self-Perception Inventory (SPI) originally published in Meredith Belbin’s book, Management Teams: Why They Succeed Or Fail (1981).
We frequently receive calls requesting information on the copyright of Belbin materials.
