how do you differentiate product and service design?

Product design is the process of creating a new product or improving an existing product. It involves researching customer needs, developing a concept, designing the product, testing the product, and launching the product. Product design focuses on the physical aspects of the product, such as its form, function, and aesthetics.

Service design is the process of creating or improving services. It involves researching customer needs, developing a concept, designing the service, testing the service, and launching the service. Service design focuses on the intangible aspects of the service, such as the customer experience, the service process, and the service delivery.
