❒ Abstract

This paper proposes models for retailing using an electronic market environment. The authors advance a set of models of virtuality to describe an electronic market consistent with popularly used definitions. These are related to electronic grocery retailing to describe avenues to efficient expansion. Virtual forms that may be adopted are constrained both by pre- defined communication links and the extent to which these can be substituted by virtual ones and also by the intensity of virtual links which define the virtual form adopted. It is argued that seven models suffice to provide and describe a comprehensive dynamic framework of change. It is suggested that for strategic advantage e-groceries must align management and communication strategies in accordance with the business model adopted but further that they need to develop a process of continual change management to reflect continuous evolution of the models in an e- market environment.

This or- ganisational form is not new, but its attractiveness as a virtual model are a consequence of the benefits flowing from low friction communications in real time and the ease with which such structures can be assembled and restructured. This form of cooperation is no novel response to business circumstances: the novelty lies in the speed and efficiency with which such alliances can usefully form, perform their tasks, and reform owing to efficient communica- tions, and hence the ease with which the other partners can treat the partners as a virtual (single) entity existing for a specified time.
