TopIntroduction
With the rapid development of the automobile industry, the automobile parts industry has become an important foundation to support the sustainable development of the automobile industry (Tzokas et al., 2004). With the globalization of the economic market, the position of the auto parts industry in the auto industry system is constantly improving (Gerwin & Barrowman, 2002). At present, China's automobile industry has been ranked first in the world for nine consecutive years, and its sales volume has accounted for more than 30% of the world share (Smith & Morrow, 1999). The increase in vehicle sales has brought about a huge demand for accessory parts, but the market share of automobile parts in China is not ideal, which is mainly due to the fact that China pays attention to the development of whole vehicles and ignores the development of components and related accessory industries (Schilling & Hill, 1998). In order to enhance the competitiveness of China's auto parts industry, it is an urgent problem to strengthen the R&D of auto parts products (Koufteros et al., 2002).
At present, a lot of research and successful practical experience have been carried out from the perspectives of management methods and development processes for improving the research process of automobile parts in China (March-Chorda et al., 2002). Some researchers summarized the whole process of product development of existing components, combined with the management model of automobile development, described the core work content and technical requirements of the product development stage, and divided the product development stage into market strategy, product planning, conceptual design, product engineering, development verification, and formal production processes (Ye et al., 2008). By analyzing the actual product development process of Jiefang Company, some researchers, from the point of view of the fact that the actual business process is not in line with reality and the process is cumbersome and unsmooth, incorporate excellent practical theory, formulate the optimization scheme of the product development process, and improve the product management system of China's automobile enterprises (Gerwin & Barrowman, 2002). Some researchers put forward a new product development process under the guidance of enterprise strategy, which transforms product ideas into the final marketing plan through a series of development, prediction, and control procedures and takes the process of successfully transforming new product ideas into products on the market as the main focus of work (Bullinger et al., 2000). Some researchers believe that the new product development process is composed of relatively independent and overlapping stages, which run through the product development process from conceptual design to product structure design, product marketing to product delivery to customers. Facing the situation of increasingly fierce market competition, automobile core components have always occupied a pivotal position in the automobile industry system (Sommer et al., 2014). In order to continue developing successfully, automobile enterprises must optimize the development process of component products (Wind & Mahajan, 1988). Taking Auto Parts Company A as the research object, this paper sorts out the concept and model of the component product development process, analyzes the problems existing in the component product development process of Auto Parts Company A based on the integrated product development (IPD) theory, and puts forward the optimization strategy of the component product development process, which provides theoretical data support for the optimization of the component product development process of auto enterprises (Zahay et al., 2004).
