Innovation and new product development (NPD) are essentially considered to be important to economic development. This study is aiming at the NPD success experience in Taiwanese food industries, and determines the key factors leading to the success of NPD performance for Taiwanese small and medium enterprises (SMEs). The research sample included 385 SMEs from food manufactures. The results have showed that customer acceptance, market acceptance, financial performance, and technical-level measurement are the four key factors for achieving success for Taiwanese food industries. Some other research findings and corresponding suggestions are also presented and proposed in this paper.
