What if you could have whatever you want, produced and provided immediately and affordably no matter how customized-with minimal environmental impact? Products, services, and experiences on demand. Just-in-time everything, everywhere, always. This radical change is already underway, as digital technologies push the production and provision of value ever closer to the moment of demand. Robert C. Wolcott and Kaihan Krippendorff provide an indispensable guide to the Proximity revolution, showing how it's transforming every industry-and our lives. Offering unparalleled foresight for leaders and innovators, they reveal how pervasive and profound this trend will be. Proximity-driven delivery represents an entirely new way to serve customers, with critical implications for corporate strategy, investing, public policy, supply chain resilience, and even sustainability. Incremental changes to existing business models won't suffice. Through interviews and compelling examples, Proximity shares stories of the people and companies leading the way. The book places rapidly advancing technologies-from generative AI and 3D printing to lab-grown meats, renewable energy, and virtual reality-in context and explores the factors accelerating the shift toward just-in-time. Proximity offers a playbook for business leaders, investors, and entrepreneurs to win this rapidly emerging game-and for each of us to consider what this revolution might mean for our lives.
