This article concurrently studies customer relationship management (CRM) and organizational excellence (OE) by pursuing three goals. First, it investigates the relationship between CRM and OE; second, it conducts a performance assessment from CRM and OE viewpoints; and third, it analyzes how each factor of CRM and each criterion of OE affects an organization's performance. To achieve the first goal, a number of hypotheses about potential relationships between CRM factors and OE criteria are proposed with the cooperation of experts and using fuzzy DEMATEL. These hypotheses are then examined using the path analysis method to find out which one is supported and which one must be rejected. Subsequently, the data envelopment analysis (DEA) approach is employed to accomplish the second goal. Finally, a t‐test is used to achieve the third goal. To implement the research in the real world, two major international airports of Iran are considered as our survey cases.
