Explores the impact of early supplier involvement (ESI) on product development practices. Develops a conceptual framework and a case study for effective implementation of ESI. A conceptual framework for ESI in product development consists of the four building blocks of design, procurement, supplier, and manufacturing requirements. Notes that, while each of the building blocks has a unique role in ESI, their interrelationships are the focus of the ESI conceptual framework. These blocks are decomposed into a set of specific tasks required to implement ESI. Applies the framework in a company that currently implements ESI in order to test and validate its viability. This comparison enumerates the examples of success and failure of ESI and two measurements of the company's ESI effectiveness. Discusses the framework's validity and proposes modifications. Additionally, presents a set of findings, hypotheses, and recommendations for implementing ESI. Also presents a set of hypotheses as a basis for future ESI theory building and testing.
