The author argues that the unidirectional measurement and evaluation of the dependence in a specific relationship is not enough to understand the existing dependence between two actors in a dyadic relationship, but a bi-directional approach may be necessary. Furthermore, a bi-directional approach may not always be sufficient to understand the dependencies in a specific relationship. The incorporation of a third actor may improve the understanding of dependencies in dyadic business relationships. Therefore, a method is applied to analyze the dynamics of dependence in triadic business networks.
