This book explores the HDL Studio Model, a unique way of bringing together the right people, a carefully framed problem, a supportive place, and an open-ended process to craft an integrated vision and sketch the pathway towards strategic improvement. It’s particularly geared towards problems that have no single owner. It includes an introduction to Strategic Design, a “how-to” manual for organizing Studios, and three practical examples of what an HDL Studio looks like in action. Geoff Mulgan, CEO of NESTA, has written the foreword and Mikko Kosonen, President of Sitra, contributed the afterword.
