Our products, services, and systems are increasingly digital, connected, and data-generating. At the same time, AI has moved from experimental to be embedded in our everyday workflow and lives. These changes raise an important question: how do we evolve design thinking so that it takes advantage of data and AI? This book is a response to that question. It does not present AI and data as a replacement for humans in design thinking, but as means to expand and augment what designers can see, explore, and do. Data can reveal what is happening at scale, and AI can help us process complexity at speed, while designers remain central for interpreting meaning and making decisions. With research-based frameworks and real-world case studies, this accessible guide will help students, educators, and professionals in design, business, and engineering innovate in today's digital world.
