All manufactured products are the result of a design process, but the nature of this process can take many forms. It can be conducted by an individual or a team, and such a team could include people with varied expertise (e.g. industrial designers, engineers, business experts, etc.). It can emphasize intuitive creativity or calculated scientific decision-making, and often emphasizes both. It can be influenced by factors as varied as materials, production processes, business strategy, and prevailing social, commercial, or aesthetic attitudes. Industrial design, as an applied art, most often focuses on a combination of aesthetics and user-focused considerations, but also often provides solutions for problems of form, function, physical ergonomics, marketing, brand development, sustainability, and sales.
