Configuring and managing strategic supplier portfolios

Acknowledging that not all supplier relationships can nor should be close partnerships, this article explores the development of strategic supplier portfolios. The strategic portfolio perspective considers risks, trade-offs, and interdependencies between the firm's array of supplier relationships. Based on over 50 interviews with managers and archival data from 12 multinational companies, a strategic supplier portfolio management framework is developed. The authors explore processes that firms use to plan, implement, and monitor strategic supplier portfolios. This research indicates that by assembling superior supplier bases, developing suppliers and integrating them into product development and manufacturing, strategic supplier portfolios contribute to competitive advantage.
