This study develops a conceptual model that explains the variation of interpersonal skills among volunteers. An overall perspective is the assumption that people can learn informally outside organizational borders. Both individual and situational characteristics are considered as important in explaining individuals behavior. The main learning mechanisms that are introduced in the model are: learning from practice, learning by modeling, and learning by information exchange.
The model developed was tested on volunteers at the Kongsberg Jazz Festival. The results from the analyses show that both individual and situational factors explain the variation of increased interpersonal skills. More precisely, motivation to learn, age, job challenge, and feedback from supervisors, are significantly related to the generation of increased interpersonal skills for the whole sample in the study. The study does not find any interaction effects. In the last section of the dissertation limitations and implications of the study are provided.
