This book introduces the reader to the changing role of design as a way of thinking and a framework for solving complex problems and achieving systemic change. It documents 80 methods that cover all stages of a design process, providing actionable guidance for applying the methods across a range of projects. The methods are complemented by seven case studies to demonstrate their application in different domains, from designing interfaces for autonomous vehicles to addressing health and wellbeing. Free templates and resources, available at designthinkmakebreakrepeat.com, make this a great resource for design educators as well as practitioners leading workshops in their organisation or looking for inspiration to transform their practice. In this revised edition, the authors look beyond the human-centred design paradigm and provide an introduction to life-centred design. This extended focus is reinforced through design methods for considering the broader ecosystem in which products and services are used, including the use of natural resources, ethical concerns and the long-term impact of design decisions.
