Innovative research solutions increasingly require deep engagement with practitioners to manage the complex problems they are attempting to solve. This often project-based research is equipped with finite resources over a limited period without much thought into future-proofing the practice. These projects must face questions of what happens when a product comes to an end and whether there are any lasting positive effects once the IT systems are no longer being actively developed. From a computing perspective, the challenge is to design IT artifacts that contribute to improving the user's work and everyday life in a sustainable way, thereby also contributing to social and ecological sustainability. Future-Proofing: Making Practice-Based IT Design Sustainable documents the experiences made by several leading research groups in Europe, North America, and South Africa. It describes their efforts to achieve sustainable design results, the difficulties that barred the way but also the strategies they adopted to achieve the goal of sustainability. The analysis of these cases has inspired thinking about how to more systematically address and possibly overcome the impediments to sustainability. This book develops a strong future-oriented perspective that conceptualizes sustainability as a complex and highly variegated issue and formulates insights and recommendations with a view to help researchers to better design for sustainability.
