Value Chain Management versus Supply Chain Management?

Value Chain and Supply Chain
Elias
The value chain of an individual company is normally part of the total supply chain of value-creating activities.
While Porter's value chain concept decomposes all activities of one firm into its parts and analyses each individual activity and their interdepencies, the supply chain concept tries to optimize the supply system as a whole by taking into account the interdependencies between the activities in multiple firms.

Value System
Hannie
A firm's value chain is embedded in a larger stream of activities that Porter terms the Value System. This value system comprises the Supplier Value Chains, the Firm Value Chains, Channel Value Chains and Buyer Value Chains.
Gaining and sustaining competitive advantage depends on understanding not only a firm's value chain but how the firm fits in the overall value system.
