Mutual understanding between Chief Executive Officers and Chief Procurement Officers is critical yet unexplored. Therefore, this study investigates how the ability of mutual perspective-taking influences the quality of collaboration and the perceived contribution of procurement. Building on two well-established social and interpersonal relationship research models, this investigation employs dyadic data analysis to examine 28 matched-pair survey responses from CEO-CPO pairs. Findings indicate that the actual stances of executives on important business and procurement subjects exhibit greater alignment than they perceive them to be, implying that their understanding of each other's viewpoints diverges negatively from their actual opinions.
