The notion of resilience is becoming an important consideration in \ addressing the needs of vulnerable individuals and groups in the public \ sector. In Information Systems development, resilience has often been \ treated as non-functional requirement such as scalability and little \ or no work is aimed at building resilience in end-users through systems \ development. In this paper we introduce a refinement of the value \ sensitive action-reflection model used in co-design, first introduced \ by Yoo et al, that recognises the tension between values and resilience. \ We report on our activities of using this approach for a project aimed \ at developing mobile apps for promoting better engagement between \ young people in conflict with the law and their case workers in the \ UK youth justice system. We examine the ambiguity created when designer \ and stakeholder prompts change their role and purpose during the co-design \ process and discuss the impact of this on resilience building for \ the end-user and the possible implications for Information Systems \ design processes.
