Assembly of contributions of elementary values allowing the final (complet) contribution to a stakeholder, on the occasion of an event. In other words, the succession of the various value segments realized to operate a transformation within a universe. The term "value" is used here in the sense of the service or provided product.
Definition & Concepts
The real value, which measures the counterpart of an exchange, can be variable, according to the fluctuations in equilibrium conditions (evolutions of markets, interactions between operators), while the composition of the product or the service is unchanged.
The value chain represents the successive contributions to the final product or service, rather than different "added value" resulting from transactions or from accounting agreements. It is thus an approach by the functions and the analyzed value which does not refer either to the price(prize) of transaction(deal), or to the production cost, or to the utility for the user.
The pile of consequentive contributions, successive and complementary, corresponds to the notion of Value Chain developed by Porter.
Value chains are organized in a stable pattern, which reveals "Strata" (layers). See "Value Layers".
We represent the strata of value chains in the vertical dimension, placing the boundary at the top of this pile of different stages of transformation. See "Value layers".
