This work, an action research, was conducted in a multinational Germany company, manufacturer of industrial gearboxes, and aimed to compare the differences between the product development process model (PDP) above and the PDP model proposed in this research, from the design of a series consisting of thirteen sizes of modular planetary gearboxes. This research is justified from the need for constant deployment tools that help to minimize costs and maximize productivity results in organizations, using as an example, the modular planetary gearbox due to its high and demand and market potential. Among the benefits found on the basis of the adopted model exchange are setting up the project teams (creation of cross-functional team), parallelism of activities (project developed and validated by a team), a better way to integrate the project's clients (meetings brainstorming and feedback) as well as the possibility to use in support of product development tools (DFMA - Design for Manufacturing and Assembly, DFM – Design for Manufacturability, among others). In addition, the practice of the new model was possible to give emphasis to consumer preferences, always considering the quality, cost and development time to market The main result, we obtained the implementation of an integrated PDP model and simultaneously with development time gain and manufacturing (70% reduction in rework elaborate designs to manufacturing and 50% of new projects development time), reducing equipment costs by 7.5% compared to the equipment developed sequentially. Through this implementation, it was still possible to draw up a catalog of modular planetary gearboxes, translated into 5 languages and distributed in more than 13 countries in Europe, Asia and America. The catalog also provided to the sellers a faster response to customers and the release of the product worldwide.
