This paper discusses the value of using design research to expose Voluntary Community Sector (VCS) organisations to design-led approaches. The discussion is based on the findings from two qualitative, exploratory doctoral inquiries into the relevance and applicability of adopting a Design for Service (DfS) approach to effect transformation in VCS contexts. Using Action Research and a case study structure, the DfS approach was introduced and applied within four VCS organisations in succession. The research findings have provided valuable evidence and insight into design’s capacity to incite transformational change, and the challenges of doing so, at a critical time for the sector.
