In today’s global economy, companies develop products not only to target a single market, but to sell them to the entire world. Companies that realize the importance of collaborative design develop regional engineering centers worldwide to balance design variations while ensuring local market success. This paradigm enables diverse customer values to be integrated into products, but also introduces challenges in the management of work distribution. Typically, workshare decisions consider the capability and capacity of the regional centers. This strategy, however, overlooks the interdependence of the design systems, leading to delays and quality problems. This paper describes a method to formulate the workshare risk based on the couplings of the design system components and to evaluate overall workshare scenario. The method involves two relationships, Component-to-Component Coupling and Workshare Coupling, and a technique to combine these two relationships to measure the workshare risk. A simple case of hair dryer illustrates the concepts, while the method is serving actual global automotive development projects.
