In this paper we present the η Framework which aims at enabling a holistic vision of Enterprise Transformation (ET) related to the adoption of Technological Artefacts. This framework is based on a Benefit-Driven approach to ET led by Stakeholders. Therefore, we focus on three interrelated components: (1) Stakeholders and corresponding classification according to their level of influence and attitude towards an artefact; (2) ET which encompasses five dimensions, namely Governance Changes, Business Model Changes, Business Process Changes, Structure Changes, and Resource Changes; and (3) Benefits classified according to their different degree of explicitness and hence importance to each stakeholder. In order to assess ET in a feasible way, we advocate mapping every single change with its corresponding benefit. Subsequently, these pairs of changes and benefits are assigned to a group of "Change Owners", who are responsible for ensuring that ET is measured and successfully achieved. Finally, we summarize the four phases of ET Lifecycle (Envision, Engage, Transform, and Optimise phase) as well as the corresponding steps required to properly apply the η Framework.
