Product design as a verb is to create a new product to be sold by a business to its customers. A very broad coefficient and effective generation and development of ideas through a process that leads to new products. Thus, it is a major aspect of new product development.

Product design process: the set of strategic and tactical activities, from idea generation to commercialization, used to create a product design. In a systematic approach, product designers conceptualize and evaluate ideas, turning them into tangible inventions and products.

Product design is sometimes confused with (and certainly overlaps with) industrial design, and has recently become a broad term inclusive of service, software, and physical product design. Industrial design is concerned with bringing artistic form and usability, usually associated with craft design and ergonomics, together in order to mass-produce goods.

There are various product design processes and many focus on different aspects. One example formulation/model of the process is described by Don Koberg and Jim Bagnellin in "The Seven Universal Stages of Creative Problem-Solving."

The product design process has experienced huge leaps in evolution over the last few years with the rise and adoption of 3D printing. New consumer-friendly 3D printers can produce dimensional objects and print upwards with a plastic like substance opposed to traditional printers that spread ink across a page.

Product designers need to consider all of the details: the ways people use and abuse objects, faulty products, errors made in the design process, and the desirable ways in which people wish they could use objects. Many new designs will fail and many won't even make it to market.
