Commercialisation is the process of taking a new product from development to market. It generally includes product launch and ramp-up, marketing materials and program development, supply chain development, sales channel development, training, and service and support growth. The purpose of commercialisation is to make the product available to consumers and generate revenue. Commercialisation often occurs after a period of research and development (R&D). During R&D, a company develops a prototype of the product and tests it to see if it works as intended. If the product is successful, the company begins the commercialisation process; this usually involves changing the product to make it ready for mass production and market launch. Once the product is prepared for launch, the company develops a marketing plan to promote it to consumers. It also works on developing its sales channels and setting up a supply chain to manufacture and distribute the product on a large scale. In some cases, commercialisation may also involve developing services and support infrastructure for the development; this is particularly important for products that require regular maintenance or have parts that may need to be replaced over time. By definition, commercialisation is taking a new product from development to market.
