In this study we question the direct relationship between alliance capability and alliance performance. We contend that this relationship is mediated through post-formation factors such as alliance management and relational quality. Drawing from the Resource Based View a model is presented that explicates these indirect relationships. Partial least squares analysis was used to test three hypotheses, using a sample of Dutch alliance managers responsible for non-equity alliances in agribusiness and the food industry. Our empirical findings affirm the hypothesized indirect relationships between alliance capabilities and alliance performance.
