This article investigated the distribution of roles, the nature of group dynamics and the level of maturity in two management groups. The participants were a group of surgeons and a group of head nurses at a Norwegian hospital. The methods used in the study were systematic observation, questionnaires, semi-structured interviews and qualitative observations. The systematic observation was performed using SPGRobserver. The questionnaire in use was also based on SPGR. The main finding was that both groups operated on a low level of maturity. The surgeons were less mature than the head nurses. Group dynamics in the group of surgeons was rigid. This was partly due to the low levels of role interchange, and partly because of the apparent existence of a hierarchy in the group. The main reason however, was that the group focused solely on assignments while neglecting the relational aspects. The study questioned whether the group of surgeons was functioning as a group at all. There were several indications of low levels of maturity in the group of head nurses: The distribution of roles was relatively fixed. The group had a permanent, visible and dominant leader. The group focused almost all its energy on assignments, and displayed few instances of the three other basic group functions, as described by SPGR. If the groups are to be of any assistance to the organization as a whole they will have to mature considerably.
