In recent years, Taiwan's manufacturing industry has gradually transformed from the Original Equipment Manufacturer (OEM) to Original Design Manufacturer (ODM) or Own Branding & manufacturing (OBM). Many corporations have also begun to think about how to further strengthen the relations between members within the supply chain. Industrial clusters began to take shape. Such clusters are linked through collaborative designs, and further gave birth to the design chain concept. Each participant uses their own unique strength in design as an advantage to form an industrial design chain and form cooperation between enterprises, hoping that such formation can promote product creativity and innovation, and departing themselves from the conventional manufacturing management.When the industry establishes such collaborative design chain, they began to review the relationships, with a degree of adjustment to each member in the design chain. Then formulate a collaborative design chain performance evaluation method as the basis to measure effectiveness as well as follow-up strategy for improvement. Intelligent electric vehicles is one of the industries being promoted in Taiwan’s industries promotion plan. The electric buses have already begun its mass production and are running on the roads. Electric buses in Taiwan is a new emerging industry. The participating partners in this industry chain have an important role in setting the intricacy and collaboration within the design chain. This study employs electric bus manufacturer A and the Design Chain Performance Evaluation (DPCE) method, through design involvement, collaborative design execution-ability, professional design-ability, and collaborative design compatibility, to build a suitable performance evaluation measures.
