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.
|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||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).|
