Every organization has a different product development process, some more structured than others. Furthermore, variations of the product development processes can exist in the same organization for different types of development projects. There are also several frameworks for product development available, such as the Stage-Gate process by Robert G. Cooper , the New Product Development process by the Product Development & Management Association , and processes based on the Toyota product development system [5, 6]. No matter which process is adopted, some steps are needed for an effective product development project, based on Ulrich and Eppinger , these steps are: (1) planning, which includes opportunity identification, project’s mission statement, and allocating resources; (2) concept development, including generating alternative product concepts to satisfy a need in the market, and selecting a few concepts for further development; (3) design, which involves defining the product architecture, including its major subsystems and components, and a detailed design with complete specifications of geometry and materials, and tooling design; (4) testing, where the product is tested in its intended environment and refinements are made based on the results; and lastly (5) production ramp-up, including manufacturing the product with the intended production system, training the workforce, and correcting any issues before full production.
