Digital product design is an iterative design process used to solve a functional problem with a formal solution. A digital product designer identifies an existing problem, offers the best possible solution, and launches it to a market that demonstrates demand for the particular solution. The field is considered a subset of product design. Some digital products have both digital and physical components, but the term is mainly used for products produced through software engineering. Since digital product design has become mainstream in the creative industry, a digital product designer oftentimes is simply referred to as a "product designer" in job posts.
