Based on knowledge resource theory, this study introduces a framework to organize supplier development activities from a knowledge-sharing perspective. In this framework, supplier development activities are classified into two categories: knowledge-sharing activities and knowledge-sharing enablers. Together, they create value for a supply chain. This framework contributes to understanding of a key issue in the practice of supply chain management – supplier development activities – and does so from a knowledge-sharing perspective. Results of preliminary content analysis support the framework and its mappings. Research results from larger-scale study along the lines indicated here can provide useful guidance for companies to carry out supplier development in practice and for researchers to accommodate supplier development in their future research.
