The term "product design" refers to the process of creating a new product or redesigning an existing one. It involves several stages, including research, concept development, prototyping and testing, as well as refining the final design for manufacturing. Product designers work with engineers, marketers, and other professionals to ensure that their designs meet both functional and aesthetic requirements while also being cost-effective and sustainable. The goal of product design is to create products that are not only visually appealing but also user-friendly, durable, and efficient.
