In this paper a conceptual framework for characterizing the Supply Chain (SC) Collaborative Planning (CP) under a process perspective is presented. When analyzing the CP process view, the definition of coordination mechanisms among SC members results essential. With the aim of identifying the possible coordination mechanisms that SC members can implement, the structural elements necessary to define them are proposed. Finally, the impact that the coordination mechanisms structural elements have on the definition of the CP process is presented. The knowledge of the CP process, the coordination mechanisms and their relationship constitutes the basis for the latter identification of potential activities that can be supported by decision tools and for the partially or totally automation of the process.
