Final answer:
True, the product development stage is indeed where the technical feasibility of producing a new product is determined. This stage involves creating a detailed design that is vital for the production and overall success of the product.
Step-by-step explanation:
The statement "The product development stage determines the technical feasibility of producing the new product" is True. During the product development stage, teams thoroughly assess the technical aspects required to bring a new product to life. This includes creating a detailed design from the initial design concept, which is critical for project success. A significant amount of time in a new product design project is dedicated to developing this detailed design, as it has a profound impact on whether the product can be produced feasibly and at scale. A poor detailed design can indeed ruin a good design concept, leading to failures in manufacturing, increased costs, or a product that does not meet customer needs or safety standards.
