Radical, systemic change is needed to create a sustainable and just society. Yet attempts at transformation often meet resistance, move slowly, or fall back into familiar patterns. This book is written for designers and public-sector innovators who confront these realities every day. The good news: systemic change is possible. Through numerous case studies, the author shows how design approaches can help drive transitions in public governance. Drawing on deep practical experience, he explains what it takes to navigate public institutions as an innovator and to move beyond abstract visions toward grounded, achievable change. Blending personal stories, societal insights and models from transition science, public administration and design, the book offers practical guidance for working in complexity and helping organizations build the capacity to learn, adapt and sustain meaningful change.
