This article highlights the organization change implications for organizations that are attempting to develop collaborative relationships with their suppliers. The research focuses on four dimensions of collaborative relations including joint buyer-supplier cost reduction, supplier involvement in new product development, delivery and logistics management, and core business strategy. A case study is presented which outlines how an organization adopted a strategy that led to extensive outsourcing and the adoption of more collaborative relations with its key suppliers. The pursuit of this strategy has acted as a stimulus for change within the organization. The article identifies a number of issues that must be addressed, including the adoption of an integrated approach to the management of strategic change, the pivotal role of senior managers as facilitators of this change, and the involvement of those most affected by the movement toward more collaborative buyer-supplier relationships.
