The key factor of promoting a firm’s competitive advantage is by means of sustainable innovation and meeting the low profit environment. For the development of new materials and new processes can promote effectiveness. Most of the research on process condition selection has been characterized by a basic approach to the problems. This study used a Taguchi orthogonal array to design the optimal experiment variables for reducing the test time and data envelopment analysis to integrate the chemicals control factor level, reaction time, reaction temperature for obtaining the efficiency selection in the process research management of thick electroless copper plating. After presenting the framework and formalization of method, the problem of searching for the best solution has been discussed. It could be constructed the product diversification to raise the research power and effectiveness of the firm’s innovation by a cyclic research and development model.
