four-dimensional sustainable e-services
DESCRIPTION
E-services are not sustainable, unless specifically designed for sustainability along four dimensions (4D): economical, technical, environmental, and social. Designing 4D-sustainable e-services is very complex, mainly due to the many challenges in communicating and assessing sustainability. This paper proposes a conceptual model that identifies the core elements of 4D-sustainable e-services. Our goal is to enhance the shared understanding amongst sustainability stakeholders, while easing sustainability assessment and negotiation. We illustrate the value of the conceptual model using a real-life case study featuring an airport baggage handling system.TRANSCRIPT

What is a sustainability model
We define a Sustainability Model as a tool to support the evaluation and visualization of Sustainability aspects.
A model is needed when we consider sustainability as a design problem, i. e. Design for sustainability

Common Misunderstanding...
Most of the Sustainability Models aim at modeling sustainability itself as a concept, rather than modeling sustainability aspects.

Our Approach
● Focused on e-services
● What does a sustainable e-service imply for each dimension?
● How can we represent the 4 Dimensions at the same time?
