This chapter compares insights from our empirical cases of three kinds of interactions: cooperation, conflict and conflict resolution, and competition. The elements of authority, information, and resources affected incentives and interactions differently. Focusing on interactions as a unit of analysis points to a variety of performance criteria that may be appropriate. These criteria for assessing outcomes and processes cannot all be optimized at once, as trade-offs are evident, and different types of interaction are likely to entail different performance combinations. In our case studies, no performance criterion scored high across all cases, and no case performed well across all performance criteria.
