Purpose The purpose of this paper is to contribute to the theory and practice of supply chain management in terms of how an organisation should structure its supply base to be resilient to supply uncertainties and disruptions. An empirical assessment of supplier response diversity is demonstrated, and the following research question posed: Is response diversity of suppliers positively associated with supply chain resilience, more positively than mere supplier diversity is? Design/Methodology/Approach Resilience is operationalised as the maintenance of sales of two food products in 27 southern Finnish retail stores during two distinct disruptions. Response diversity is operationalised as 1) diversity in the personnel sizes of slaughterhouse suppliers of pork under domestic strikes and as 2) evenness in the proportions of imports and domestic supply of food oil under global price volatility. A five-step quantitative assessment is performed. Findings Response diversity is positively related to the maintenance of sales, more positively than diversity of individual suppliers is. Social implications The proposed approach is useful for teaching and for authorities to enhance food security. Originality/value This first assessment of response diversity of supply chain operations presents an important advancement in the theory and practice of supply base management for resilience.
