Abstract: The complexity in supply networks is increasing and influences the competitive position of the focal company. Traditional approaches like supply chain mapping only show the focal company's relationships with suppliers and customers along the vertical supply chain, but are not capable to map any horizontal buyer-supplier relationships with other companies. Hence, this paper introduces a new supply network map structure model that extends the multi-tier view towards suppliers and customers along the vertical supply chain also to the complementors and competitors across the horizontal supply chain. Thus, the model enables the development of the existing supply chain mapping theory further into a holistic supply network mapping method. The model has been conceptualised with the help of 13 semi-structured interviews and is based on relevant models from the strategic management and the purchasing and supply management (PSM) literature. According to design science, it has been refined in several iterations.
