Final answer:
True, the commercialization phase of new-product development involves refining and finalizing plans for manufacturing and marketing, which is essential for a successful product transition from design to market.
Step-by-step explanation:
True: During the commercialization phase of new-product development, plans for full-scale manufacturing and marketing are indeed refined and settled. This phase is critical as it involves the transition from design to the market, where the detailed design process is crucial for the success of the product. A poor detailed design can ruin an otherwise good design concept, highlighting the importance of selecting the best choices for production during the development phase. After research and development are completed, the selection process for the best ideas and details takes place, leading to the implementation of the design. This includes locating suppliers for components, deciding on facilities for manufacturing, and identifying a sales and marketing team. During this phase, it is paramount to remain flexible and adaptable to change, as unforeseen challenges may arise.
