The decomposition of processes into sub-processes and sub-steps provides valuable insights to support decision-making and optimize the overall process operation. However, the evaluation method should be both objective and reliable and include multiple criteria in the evaluation. Data Envelopment Analysis (DEA) is a method for evaluating the efficiency and identifying best practices of organizations, depart-ments or processes, for example. The specifics of the object under investigation can be explicitly consid-ered in the modeling. In order to evaluate multi-level processes, such as supply chains, so-called Network-DEA approaches are receiving increasing attention. The paper provides an overview of network DEA and its relevance to supply chain assessment. Subsequently, the presentation focuses on the assessment of supply chain sustainability. For this purpose, the possibilities as well as the potentials and drawbacks of DEA are demonstrated by means of a practical example.
