The difference between research and development and product development is that research and development is the conception phase in the product life cycle, while product development is the entire process of designing, creating, and marketing new products or existing products with new features.
Research and Development
In research and development, a company conceptualizes entirely new products. The research portion occurs when a company's research and development team tests the viability of a potential product by coming up with completely new science. This is the act of discovering entirely new science that can be used to create new products. The development portion comes after the research and is the act of turning the discovered science into a useful product that the company can market and sell.
Companies invest in research and development when their product lines become outdated or competitors come out with similar or superior products. Research and development is vital for the sustained growth and success of a company.
On the other hand, product development is the entire process of researching, designing, creating, marketing and selling new products. Research and development is essentially the first step in developing a new product, but product development in not exclusively research and development. It is the entire product life cycle, from conception to sale.
Product development is also not exclusive to designing, implementing and selling new products. Existing products can go through product development to revamp old features or add new features so the product sells better or adds greater value to consumers. Any time a new product is created and sold – or any time an existing product has added features and is resold – it is going through product development.
