SHORTLISTED FOR THE 2026 SMART THINKING BUSINESS BOOK OF THE YEAR
What if the fact that no one can help you at your bank, doctor's office, airline, or job - you name it - is on purpose?
In One Size Fits None, social entrepreneurship experts Alejandro Juárez Crawford and Miriam Plavin-Masterman argue that the systems powering our experiences are unresponsive by design; they often run on "best practice" templates imported wholesale from somewhere else and applied to people and places they were never built for. In a fragmenting world, that top-down, one-size-fits-all approach is breaking down, and the cracks show up everywhere: in workplaces, hospitals, schools, and city halls, and in our collective inability to make progress on bigger problems like climate change, housing, and food.
The book goes beyond just highlighting these failures. Pairing an accessible style with sharp analysis, One Size Fits None shows that it doesn't have to be this way.
Drawing on original research conducted across 20 countries, the authors point to something already taking shape: a borderless, entrepreneurial ecosystem of people using digital tools to build the solutions the imported playbooks couldn't. This loose network of innovators—working across industries and borders—is emerging as a stabilizing force precisely because it starts from the opposite premise of "best practice": trust the people closest to the problem.
When we make it practical for the people facing unresponsive systems—employees, patients, students, community members—to build new ones that actually meet their needs, they rise to the challenge. We change from passive "users" to engaged participants equipped to shape the systems in which we live and work.
One Size Fits None is relevant to management and business readers looking to change organizations; researchers, students, and leaders focused on social entrepreneurship, innovation, or sustainability; and anyone who's ever wondered why things just don't quite work.
To learn why systems have become unresponsive, what can be done about it, and how to bring this approach to your organization or community, order the book here.

One Size Fits None is a must-read for anyone grappling with the systemic breakdowns that seem to define our era—whether it’s crumbling infrastructure, institutions, deepening climate crises, or increasing alienation in customer service. Instead of searching for a single, scalable fix (Go Big or Go Home), the authors challenge us to rethink problem-solving itself: How might we empower a generation hungry to make a change, the way Apple and Microsoft once empowered hundreds of millions through personal computing? What if we empowered local innovators to develop solutions tailored to their communities while learning from each other in real-time? The real challenge, the book argues, is redefining who we believe has the power to innovate. Backed by original research, this book makes a compelling case that such a shift is not only possible but necessary within the decade. A revolution isn't sparked by one person alone, but by countless people experimenting, sharing, and building change together.
One Size Fits None holds the blueprint for an innovation revolution. Crawford and Plavin-Masterman argue convincingly that the biggest challenges we face today — from climate change to disruption from technological change, to unresponsive corporations, governments, and institutions — require a completely different approach to finding solutions. The key to a better future comes from broadening who gets to innovate through developing experimentation as a mindset. Following the authors' journey over years of practical application of their methods shows that, not only will the solutions not come from the traditional halls of elite entrepreneurs, venture capitalists, and private equity bankers, but the solutions will be far superior when developed at the local level by those who are most familiar with the problems at hand and arrive, through experimentation, at outcomes that would benefit them directly.
One Size Fits None strips away the hype of AI, algorithms, and Big Tech invincibility, and confirms their real effects on our lives – then shows us a better way. Yes, technology can seem able to do anything for us, not only help us buy or stream anything we want with one click, but also serve all our lifestyle desires. While tech visionaries rhapsodize about it as companion, babysitter, teacher, and co-author, we’ve all become part of a “cattle class” struggling to get the help we need because it isn’t one of the menu options. One Size Fits None reminds us that the better way is human ingenuity; data shows that real people can develop real solutions that actually work – for us. This brilliant book will make you feel seen, and inspire you to take back the initiative and seek solutions among the wildly diverse, messy miracles of humanity itself.
We’ve all been victimized by the ‘doom loop,’ where no well-informed human can ever answer our urgent questions about our bills, our 103 degree fever, our blue-screen computer, the climate crisis, you name it. One Size Fits None explains how we got here, how much damage these loops are causing, and–most importantly–how we can escape them. The simple solution, the authors argue, is to scale down our businesses and unleash millions of small-scale enterprises capable of delivering personalized and localized goods and services. They persuasively show that we have the right tools–of design, ingenuity, and capital–to create these kinds of solutions, if we’re smart enough to use them. And there’s no better book to explain what these tools should be, and no better time to deploy them than now.
“Reading One Size Fits None felt like someone had finally put into words a lot of the ideas I’ve been thinking about regarding work, leadership, and the kind of company I’d like to run one day.”
“This book made me rethink leadership as a whole and I don’t just want to manage processes or check boxes, but I hope to actually lead people in ways that empower them to innovate, grow, and feel like they can actually make a difference.”
“Reading One Size Fits None really shifted how I think about management going forward. One of the biggest takeaways for me is that there is no single “right” way to run a business, and effective managers have to be able to adapt their approach based on the situation, the people involved, and the long-term impact of their decisions.”
“Reading One Size Fits None has fundamentally shifted my perspective on what it means to manage in a modern organizational context.”
