Hi Shabnam, we can say that the Value Chain is part of a Value Net. A value chain is a sequence of functions operating in order to produce a value (product or service) for customers. Imagine a car making company from mines and steel factories, various parts manufacturers, assembly line, dealers and customers. This semi- series line can be called a value chain (compatible with the vertical pivot in the above chart. The main players or actors in a value chain are suppliers, company and customers. But in value net we may have other players like competitors who may be included in other value chains (different from ours).
