Introduction Please note: this is not just a book about methods of design. Yes, we know what the cover says. But the truth is, we believe that the power of the methods and techniques included in this book is that each provides an opportunity to structure conversations that can help us better understand and empathize with people, and as a result build more meaningful products. When we set out to write this book, we admit that we began with the simple intention of aggregating 100 different ways to collect user-centered research data, synthesize and analyze information, and communicate results and design implications. But over the course of our writing process, we realized that integral to the methods and techniques are the conversations that they facilitate--conversations with stakeholders, team members, clients, and most importantly, with the people who will ultimately use designed products, systems, and services. We realized that these methods and techniques have a role to play in how the design community can establish expertise and build credibility, because they can help designers have the right conversations at the right time. Professional and academic excellence requires situating and articulating new knowledge in a timely and approachable manner. The 100 methods, techniques, and deliverables in this book have the potential to do just that. In keeping with the work that we do, we have a simple, human-centered design intention in the presentation of this book. Methods and techniques are organized alphabetically for ongoing, quick reference. On each page spread, accessible, concise text descriptions of each method appear on the left page, accompanied by references for further reading that pay respect to
