Purchasing portfolio models have received great attention during the last two decades. Thesimplicity of application and the focus on power-dependence balancing has been appreciatedby practitioners and academics alike. In this paper we argue that the starting point in 'given'products in addition to a dyadic perspective on purchasing management may be counteractivewhen purchasing efficiency is concerned. First, the object of exchange is not 'given' whenfirms interact, but may be subject to continuous development. Second, the dyadic perspectivemay obscure potentials for enhancing productivity and innovativity since both parties haveother relationships that impacts on the collaboration between them.
