Product design describes the process of imagining, creating, and iterating products that solve users' problems or address specific needs in a given market. The key to successful product design is an understanding of the end-user customer, the person for whom the product is being created.
UX/UI should be seamless, intuitive and effortless to the user. Part art, part technical, and part psychological, great product design is both challenging and rewarding.
Product management is an organizational function within a company dealing with new product development, business justification, planning, verification, forecasting, pricing, product launch, and marketing of a product or products at all stages of the product lifecycle.
