Accessibility isn’t just a legal requirement or a checkbox - it’s a catalyst for innovation, inclusion, and lasting impact. This book is a compelling call to action for leaders, changemakers, and anyone ready to reimagine accessibility as a strategic advantage rather than a technical hurdle. This is not a manual or how-to guide. Instead, it’s a powerful exploration of the 'why' behind accessibility and the transformative potential it holds when woven into the fabric of an organisation’s mission and mindset. Drawing on interviews with global industry experts, the voices of people with lived experience, and insights into the legislation and international policies shaping our world, this book builds a vivid case for accessible design as a force for good and a driver of value. From boardrooms to policy rooms, from product teams to public services, Joanna and Fernando invite readers to think bigger: to see accessibility not as an obligation, but as an opportunity to lead with purpose, reach more people, and future-proof their work for a more inclusive tomorrow. Whether you’re just beginning your journey or looking to deepen your strategic approach, this book will help you to make accessibility a core part of how you lead, create, and grow. ** Including an exclusive foreword by the Future Generations Commissioner for Wales.
