This research study explores in general the nature of a private general medical practice [PGMP] and whether analysis of the PGMP as a social system can lead the Group Dynamics Practitioner towards developing interventions that will enhance group effectiveness in the PGMP support staff group. The main assumption is that, through the application of a framework of analysis based on that of G. C. Homans and the AGIL functional prerequisites developed by T. Parsons, a structured analysis of the external and internal variables that impact on the PGMP as a social system can be undertaken. The findings of the analysis would lead to the formulation of interventions that would improve the performance effectiveness of the PGMP as a social system. Following a two-questionnaire survey of 17 practices that provided demographic information as well as soft skills training needs, a single PGMP was identified for the case study. Data pertaining to the group as a social system were collected, and by using direct observation, content analysis and a sociometric test, the practice support staff sub-system, being the main focus of this research, could be analysed. By linking the findings to the elements of the framework of analysis, areas of ineffective group functioning could be identified and interventions suggested. This research indicates that the choice of soft skills is associated with the nature and size of the practice, as well as the dynamics of the sociometric patterns characteristic of the relations within the practice support staff subsystem; that while some practice support staff have preferences for sociometric task and socio-emotional relations outside their work clusters, these seem to serve as a buffer against clique forming, thus enhancing the function of integration within the social system as a whole; and that the physical practice layout, and the interaction dynamics that it creates, tend to hinder integration between the members of the practice support staff group, as a social subsystem.
