Value-sensitive co-design for resilient information systems Balbir Barn and Ravinder Barn and Giuseppe Primiero Abstract Resilience is becoming an important and alternative response to provi- sion of services in the state sector and has been the subject of much examination in the social sciences and psychology literature. In Information Systems develop- ment, resilience has often been treated as a non-functional requirement and little or no work is aimed at building resilience in end-users through systems development. The question of how values and resilience (for the end-user) can be incorporated into the design of systems is an on-going research activity in user centred design but remains largely absent from method engineering research and its formal area. In this paper we offer a critique of the intrinsic relationship between values and resilience, evaluate it within the context of an ongoing software development project and con- tribute a formal model of co-design based on a significant extension of Abstract Design Theory. We argue that value-sensitive co-design enforces better resilience in end-users. 1 Introduction Modern information systems place possibly unsustainable demands on the need to preserve key moral and epistemic values such as privacy, security and autonomy. Failure to address these demands may have a detrimental effect on the resilience of end-users and ultimately affect the acceptance of new technology. However, in- volving users and their values in the design process is manifestly difficult and while much progress in value-sensitive co-design has been made, the nuances of how val- Balbir Barn Middlesex University, UK, e-mail: B.Barn@mdx.ac.uk Ravinder Barn Royal Holloway, University of London, UK, e-mail: R.Barn@rhul.ac.uk Giuseppe Primiero Middlesex University, UK, e-mail: G.Primiero@mdx.ac.uk 1
