Accessibility Value Chain

This series of pages will explain the concept of the “accessibility value chain“.

In order to understand that concept, let’s look at the basic idea of a value chain. This concept was first put forward by Michael Porter, who wrote about it in his book Competitive Advantage: Creating and Sustaining Superior Performance (1985). Simply stated, a value chain is the recognition that the value of a product is created by a manufacturer plus a lot of other players: component vendors, distributors, retailers, and end users all contribute value.

In this diagram, the farmer receives seeds, fertilizer, pesticides, water, etc. from other entities; the product of the farm is further increased in value by many other entities, such as supermarkets and restaurants.  Without a robust chain of participating entities, not as much value can be delivered to the user.

Value chains can be used to analyze the total social benefit from products and services, and to clarify and refine the relationships between and among links in the chain.

      Thanks, Vincent. I don’t think all value comes from within an organization. Especially in accessibility, consider how much value is provided by end users, even when they’re not customers. Policy makers, researchers, competitors, and many other entities also add value. I guess my point is that value is added along the supply chain, but not exclusively, and not always in a cascade — downstream participants may be as useful as upstream ones.

  3. This is definitly a supply chain. Porter’s definition of value chain is for a single business generating value. How different functions are positioned within a company impacts on the value chain efficiency and, as a consequence, on the supply chain’s efficiency, but does not affect neither change the supply chain structure.
