A basic premise of inter-organisational research, from a number of different theoretical perspectives, is that selected organisations should work in harmony rather than competition with each other in order to enhance business success. From this perspective, a review of the literature reveals that three related topics are co-operation, coordination, and specific assets. Yet these constructs have not been examined together in empirical research. This study examines the relationship between these focal constructs and two antecedents (trust and commitment) and one consequent (satisfaction). As predicted, commitment leads to co-operation, coordination, and specific assets. Yet, only co-operation and coordination leads to satisfaction with the relationship. Although trust leads to co-operation, trust has a negative relationship with specific assets, which in turn, leads to lower levels of satisfaction with the relationship.
