Product design is the process of creating products that satisfy user needs while meeting business goals. This important, multifaceted process requires not only design skills but also the ability to conduct customer research, oversee rapid prototyping of new product ideas, and develop a marketing strategy that ensures a successful launch. An effective product design process typically includes repeated iterations in response to user feedback in order to ensure the development of profitable products with a strong product/market fit.
While product design is applicable to the development of both physical and digital goods and services, the rapidly growing market for software, websites, mobile applications, and other digital products has led to the creation of new terminology specific to product design in this area. For example, user experience (UX) and user interface (UI) design is an aspect of product design that studies how customers interact with digital products, which is refined through a process of usability testing and user research.
