Segregation of product development and manufacturing process creates an engineering problem in concurrent engineering application. Commonality analysis has never been used for solving this problem, but rather solely as a product development tool. This paper focuses on coordinating the manufacturing and product development process to produce supply chain agility. The purpose of this paper is to present a novel approach to managing the product development process by considering strategic safety stock allocation to decide on the customer order decoupling point. The new approach to commonality analysis by multi criteria decision making and vector analysis is developed by optimising the safety stock allocation. The results show that the safety stock allocation increases product commonality. Furthermore, it increases the whole product family profitability by lowering total costs. Product reconfiguration should be carried out in the future in considering safety stock placement. In terms of managerial implication, coordination between the manufacturing process and product development department facilitates supply chain design.
