The digitalization of supply chains offers great opportunities, especial-ly with regard to procurement. To effectively implement innovative concepts, it is necessary to evaluate procurement departments' current situations and create target-oriented recommendations for action. Suit-able maturity models can help to achieve these goals effectively. However, most existing models do not consider the specifics of pro-curement and Industry 4.0 technologies and fail to define realistic digitalization goals. In this paper, a model called MAP 4.0 is proposed to assess procurement organizations' maturity and derive realistic tar-get conditions. A qualitative and deductive methodology is applied to analyze existing maturity models. Based on the findings, the maturity assessment model MAP 4.0 is developed according to the methodolo-gy of de Bruin et al. (2005). By focusing on the specific field of Procurement 4.0, the requirements and needs can be considered in more detail. In addition, target states and recommendations for actions can be devel-oped. The model includes the relevant dimensions of digitalization and defined weighted items for measurement. In this way, the study lays the foundation for future research, provides valuable insights for procurement managers, and can contribute to the digitization of procurement.
