VDML roots: e³value

This post will give more detail about the mapping of e³value to VDML.

This modeling language for evaluation of the viability of e-commerce business models or value constellations, e³value, as presented by Gordijn and Akkermans (2003, 2004), represents a group of economically independent entities, including market segments, that exchange transactions with economic value for mutual benefit. This seems straightforward, but in e-commerce the number of entities, their different interests and multiple exchanges can obscure the net value realized by the different participants. Each of the participants must have a sustainable business model for the overall exchange to be viable.

Mapping of e³value concepts to VDML concepts
VDML Concept e³value Concept Remarks
Actor/collaboration Actor In e³value, an actor is restricted to an economically independent entity. An economically independent entity in VDML may be an actor or a collaboration. The
collaboration will generally be specialized as a community (representing a set of potential actors such as a market segment) or an organization unit such as a company.
Business network Composite actor A business network may have supporting business networks. A supporting business network consists of parties working together to participate in a parent
business network.
Business network Constellation A collaboration/exchange of complementary transfers of value between independent business entities.
Deliverable flow Dependency element In e³value, a flow within a business entity. In VDML, flows are between activities and roles (through activities) internally or externally.
Community Market segment A market or market segment is a community of potential parties in a business network or other collaboration.
Scenario Scenario Similar concept of applying different circumstances to evaluation of the viability of the model.
Activity Value activity Value activity is a collection of operational activities which can be assigned as a whole to actors.
Business network Value interface Not explicitly defined in VDML but is the aggregate of value propositions provided and received by one party in
a business network. So a business network determines the scope of value interface of each party.
Business item Value object The thing that is provided or received, which is of economic value for at least one of the actors.
Value proposition Value offering May be a value proposition as well as a value proposition that represents the aggregation of value propositions provided or received.
Port Value port The point of departure or receipt of a value object/business item.
Unit of production Value transaction The set of value objects and transfers that represents a complete cycle of exchanges between parties in a constellation such that their net gain/loss can be assessed.
Deliverable flow Value transfer Flow of value between business entities (actors in e³valueor parties in VDML).
