Open labs provide spaces for interaction across organizational boundaries. They have lately become a very popular approach to facilitate participatory innovation processes in many different contexts. The book investigates how such processes are implemented and managed. It brings together contributions from leading experts in the fields of engineering, design, strategy, foresight and marketing research as well as practitioners from JOSEPHS®, an open lab in Germany. The topics addressed in the different chapters include: interaction patterns and mediation in open labs, innovation technology, resource management, ecosystem and platform design, cultural translation, productivity and multi-channel communication.
