Notes: What are Value Chains? The value chain describes the full range of activities that are required to bring a product from its conception, through its design, its sourced raw materials and intermediate inputs, its marketing, its distribution and its support to the final consumer. In other words, the chain can be seen as incorporating production, exchange, distribution and consumption - from the cradle to the grave of a given product or service.
