This paper consists in a deep analysis of both the professional experience of individuals and the performance of the group. This research focuses simultaneously on the effects of the accumulation and the diversity of professional experience on team performance by proposing a typology. This typology has been tested on Brazil football team, who played the fifteen FIFA world cups (1954-2010). Results show that the accumulation of experience due to the selection of the most experienced does not ensure the highest performance of the group. On the reverse, the less experienced teams who count a few “experts” represent the most efficient configuration.
