This book examines returns on experience and managerial practices to generate deeper collaboration, intensify co-creation, support start-ups and established companies to explore, develop, and accelerate their projects thanks to open labs (living labs, fab labs, coworking spaces, "third spaces", etc.). Open labs are the beatbox to create a rhythm in ecosystems and make all stakeholders move forward, faster, together. This book proposes a framework to understand how open labs, innovation hubs, and collaborative spaces contribute to ecosystems.
