As designers and researchers grapple with more systemic issues, we need to hone our tools and refine our language. Visualising complexity is one of the key ways that we add value in highly collaborative settings and it is something that sets us apart. How can we further add value through mapping? Explorers: Thoughts on Mapping in Design Research brings together learnings and conversations around this topic. With generous contributions from leading pioneers, we explore the work of innovators in our own fields and venture across disciplines for insight into how others go about mapping. We hope this collection of thoughts and maps will spark fruitful discussion and reflection in design studios, research departments, boardrooms, and beyond.
