International experience is identified as a firm's or a team's resource, to be more precise as a form of tacit knowledge. International experience as a resource is likely to contribute to a firm's or a team's performance. Team managers are assumed to exploit the performance potential of international experience via two distinct mechanisms, namely via resource-picking and capability-building. The aim of this thesis is to identify and illustrate the impact of international experience on the performance of national football teams participating in a major tournament. Descriptive statistics, as well as concrete multiple regression models are developed. Various dependent and independent variables are calculated. Following an extensive description and illustration of the obtained data, two multiple linear regression based models are developed to test five concrete hypotheses relating international experience with performance of football teams. The obtained results render strong support for the hypothesized relationships between three different measures of diversity in international experience inherent in a team and short-term team performance.
