Electronic Business Media

According to Schmid, media can basically be defined as follows: They are enablers of interaction, i.e. they allow for exchange, particularly the communicative exchange between agents. Such interaction enablers can be structured into three main components:

First, a physical component (C-Component) allows for the actual interaction of physical agents. This component can also be referred to as carrier medium or channel system. Second, a logical component (L-Component) comprises a common “language”, i.e. symbols used for the communication between agents and their semantics. Without such a common understanding, the exchange of data is possible (with the help of the C-Component), but not the exchange of knowledge. Third, an organizational component (O-Component) defines a structural organization of agents, their roles, rules which impact the agents’ behaviour as well as the process-oriented organization of agents’ interactions.

Together, these basic three components have been identified to constitute various kinds of media. Among others, it is appropriate to describe electronic media such as those deployed to support cross-organizational collaboration. Based on these components which already represent a first, scientific approach to modelling, understanding and reorganizing media, a layer/ phase reference model has been introduced as well.

The Media Reference Model (MRM) comprises four different layers (which all represent dedicated views on media) and structures the use of media into four sequential phases. Similar to the emerging field of software engineering in the software context, the MRM aims to provide a comprehensive, coherent and systematic framework for the description and analysis of various media.

The Community View (first layer) thereby accounts for the set of interacting agents, the organization of the given agents’ population, i.e. the specific roles of involved stakeholders, the situations in which they act as well as the objects with which they deal. Summing up, it models the structure of the social community sphere in a situation-dependent, but static fashion. The Process View (Implementation Aspects) deals with the modelling of the process-oriented organization of agents and can also be referred to as “Interaction Programming”. It is also called implementation view as it connects the needs of the community with the means provided by the carrier medium and thus implements the “community-plot” on the basis of the carrier medium. The Service View (Transaction View) models the services provided by the carrier medium which can be used in the different interaction steps to reach the respective interactions’ goals. The Infrastructure View models the production system, which creates the services provided by the service view, i.e. in the case of electronic media the actual underlying information technology.

The above discussed three major components can seamlessly be integrated into the MRM: The upper two views (Community Aspects and Implementation Aspects) represent the organizational component (O-Component) which accounts for the structural as well as process-oriented organization. The lower two layers are mapped to the physical component (C-Component) which focuses on the creation and provision of services. Last, the logical component (L-Component) concerns all four layers as it ensures that interaction of agents is based on a common understanding of exchanged symbols. Wikipedia
