This article aims to integrate capability-based theory into purchasing management. The research model presented in the article focuses on the effect of supplier evaluation capability and risk management capability on delivery performance. Further, the article explores the moderating effect of demand and technological uncertainty. The methodology relies on a multiple informant survey design with responses from purchasing and production managers in Danish manufacturing companies. Hypotheses are tested using regression analysis based on data collected from 197 firms. Risk management capability is found to increase delivery performance. Unexpectedly, supplier evaluation capability was found to decrease delivery performance. Demand uncertainty has a negative effect on delivery performance. Technological uncertainty had no effect on delivery performance. The results are discussed in detail in the final section of the article.
