Smart products are the future of the smart connected world. Digital transformation has radically changed traditional manufacturing processes through new collaborative connected product development to smart manufacturing. Smart product development is essential for almost all manufacturing industries today. In this chapter, the different stages of the smart connected product development process have been discussed – from quality function deployment through post launch. Smart products bring with them lots of brand-new barriers and challenges. New product development teams are changing from a majority of mechanical engineers to proficient engineers of numerous disciplines, and manufacturers have the ability to check specifically how their products are utilized in actual time with the help of sensing units and also systems attached to the Internet/intranet within the product. In addition, the touch base on the smart product ecosystem enables manufacturers to have incredible access to a constant stream of up-to-date insights into the product.
