A model of e-business transformation is developed for ERP enabled organisations, based on the findings of a longitudinal multiple case study analysis of SAP sites. The model is represented as a matrix along three stages of e-business growth. The theory embedded within the matrix recommends that successful e-business transformation with ERP systems occurs when B2B value propositions are realized through integration and differentiation of technologies, used to support new business models for delivering products and services online. In addition, the management focus evolves through employee self-service and empowerment towards extensive relationship building with e-alliances. The matrix can be used by ERP business managers to guide their strategies for organisational transformation but also highlights critical stages of change.
