Global competition is forcing firms to rethink the question of how new organizational knowledge is acquired. New knowledge provides the foundation for new skills, which in turn can lead to competitive success. However, few firms systematically manage the process of knowledge acquisition. This paper explores international strategic alliances and their potential for learning and knowledge acquisition. In bringing together firms with different skills, knowledge bases, and organizational cultures, alliances create unique learning opportunities for the partner firms. Based on the assumption that organizational learning is both a function of access to new knowledge and the capabilities for using and building on such knowledge, the paper focuses on alliance knowledge accessibility and firm learning effectiveness.
