Contextual Design is a user-centered design process that uses in-depth field research to drive invative design. Contextual Design was first invented in 1988 and has since been used in a wide variety of industries and taught in universities all over the world. It is a complete front-end design process rooted in Contextual Inquiry, the widespread, industry-standard field data gathering technique. Contextual Design adds techniques to analyze and present user data, drive ideation from data, design specific product solutions, and iterate those solutions with customers. In 2013, we overhauled the method to account for the way that techlogy has radically changed people's lives since the invention of the touchscreen phones and other always-on, always-connected, and always-carried devices. This book describes the new Contextual Design, evolved to help teams design for the way techlogy w fits into peoples' lives. We briefly describe the steps of the latest version of Contextual Design and show how they create a continual immersion in the world of the user for the purpose of invative product design.
