What is Product Design?
Product Design, UX Design or User Experience Design is the digital or physical process of designing a product that is useful, user-based, easy to use and fun to interact with. Essentially, it is bettering a product by enhancing the way users interact with it. Along with creating a great product, it is also the process of making sure there is value found in the product you're putting out.
