In current research on the team roles played by staff, prevailing methods have been de-veloped on the basis of psychometric techniques. These techniques allow us to define per-sonnel’s predispositions and their potential to play specific roles in teams. The authors’ con-cern was to verify this attitude from the point of view of the staff taking effective roles. In the research a sociometrical technique was applied, that presently forms part of a more wide approach to the study of organizing Social Relations Analysis which consisted in studying relations between different subjects. In the pilot research 3 task teams operating in public administration participated. The results indicate that application of the sociometrical method allowed us to capture differences between the effective roles played in a team and the potential defined with the use of methods based on psychometric research.
