| Abstract: | This paper advocates early supplier involvement in the early phases of product design and development in a concurrent engineering environment. A concurrent engineering environment and the benefits of such involvement are explained in detail. The paper then focuses on facilitating an interface and collaboration among designer, supplier, and buyer at three planning horizons: strategic, intermediate, and tactical with respect to product design and development. A set of propositions and corollaries for each area of interface at each level of planning are proposed. These propositions and corollaries are intended to effectively accomplish the design-based sourcing and early supplier involvement. Then, each proposition is evaluated in practice and the extent of difference from theory to practice is discussed. Finally, concluding remarks and an assessment are presented. |
