The document discusses the shift from a "Mobile First" customer experience design strategy to a "Context First" strategy. It argues that while Mobile First recognized the importance of mobile devices, it had limitations because it focused only on mobile as the primary touchpoint rather than considering the full context of the customer's experience. Context First takes a broader view, using mobile devices and other data to understand the customer's complete environment, needs and goals in order to deliver highly personalized experiences. Examples of companies taking a Context First approach include EpicMix Ski and Rebecca Minkoff Digital Changing Rooms.
