Purpose A shortage of skills is recognized as a major source of risk in supply chain networks. This study uses two independent organizational theories to explain how to build applicable skills for continuous availability of appropriate supply chain talents. The purpose of this paper is to propose an integrated framework that links human agency theory, social capital theory and supply chain skill. Design/methodology/approach This framework is analyzed in third party logistics (3PL) organizations by confirmatory factor analysis and tested using a survey. After pre-testing by six academics and six practitioners, and following the total design method, the data were collected from 183 3PL organizations in India. Data were checked to ensure no non-response bias. Research hypotheses were tested using WarpPLS-structural equation modeling. Findings A primary finding offers guidance to 3PL managers. Their driving role and mediating role of access to information and access to resources facilitate building supply chain skill. Leaders who invest in library, acquiring e-resources, offer financial support and create trust among employees are enablers of building supply chain skill. Originality/value This study classified 14 supply chain skills into three categories as: managerial skill, quantitative skill and supply chain core skill. The study could be extended to similar companies in other developing countries.
