Meurer, JohannaMüller, ClaudiaSimone, CarlaWagner, InaWulf, Volker2018-06-012018-06-012018Achieving the sustainability of IT-based solutions is a challenge. We will argue in this paper that it is helpful to conceptualize designing for sustainable IT-based solutions as taking place in a multi-dimensional space. It requires thinking about how a project is framed; the perspectives and commitments of the project partners; the type of innovation that is foregrounded; the motivations and needs of the user group; and the level of sustainability a project or research program may achieve. The paper describes some of the challenges and possible solutions by revisiting a portfolio of projects that developed IT support for elderly people who continue living in their own homes.enICT designSustainabilityElderly peopleAppropriationCapacity buildingFunding schemesCollective learningText/Journal Article10.1007/s10606-018-9317-1ISSN 0925-9724
