The value chain is a strategic approach that analyzes the relevant activities in a value creation process and assigns them to the value chain. The concept of the value chain is based on the work of Prof. Michael Porter of Harvard Business School, published in 1985.
According to Michael Porter's concept, all activities by which a product is designed, produced and distributed enter the value chain. According to Porter, in a value chain, all the resources consumed are linked to the values created. Porter divides value chains into inbound and outbound logistics, production, marketing, and service. In addition, there are human resources, corporate structure and development. Each company department makes its contribution to value creation.
In addition to the production of products, there are also numerous examples of value chains on the Internet. For example, the production and distribution of books, which are created digitally as e-books and distributed via the Internet through downloads.
