This paper discusses the results of a correlation study performed at Stockholm University, which investigated the possible connection between the make-up of security risk management teams and their performance. Three different models were used to construct team composition profiles and were (separately) tested as the seven participating teams completed two practical security risk management tasks. The study has shown that there is a possible correlation between the teams' diversity in terms of the combinations of work related preferences and tendencies (including both risk management specific ones, and non-specific to the risk management context) of their members and the teams' performance.
