Many companies are trying to build the new product development systems for a concurrent engineering and collaborative environment. Out-sourcing of both design and build activities is appearing to be one of the most important strategy in recent business activities. Two approaches emerged to deal with data exchange problems: If a company is mandating the use of only one CAX(CAD M/E/T) system, their design productivity will be lower, and if a company uses heterogeneous CAX systems, their data may rapidly become out of control and therefore increase costs. Therefore the strategy of data exchange measured by design productivity and Return on Investment(ROI) is required in each company, when CAX system is implemented currently or in the future. This study suggests a process model of CAX strategy establishment for CAX strategy implementation. Under the definition of CAX strategies, Hybrid Approach Method that is mixture of inductive approach and deductive approach is helpful to find an effective strategy.
