The evolution of agile UXD

Context: Agile User eXperience Design (Agile UXD) is a current theme and a trending topic for the future of software development. The integration of UX Design within Agile development is seen as one of the frontiers for Agile Methods as a balance between upfront design as advocated by UX and the you-ain't-gonna-need-it (YAGNI) principle from the agile community must be found.Objective: In this paper, we analyze the evolution and current state of Agile UXD to provide a brief overview of the topic and to point out still unaddressed gaps, challenges, and future trends.Method: We systematically analyzed the existing research literature on how this topic evolved over time. We identified three categories with distinctive sets of work and classified them as Early, Middle and Recent years.Results: We noticed that the Process and Practice dimension has already crossed the line that separates Agile and UXD, the People and Social dimension is crossing this line right now, and the Technology and Artifact is the dimension that took the longest to be addressed, and it did not cross the line yet. Crossing the line means that there is already a full understanding from the Agile side of UX needs and vice versa.Conclusion: Agile UXD is a need for today's software development teams. However, integrated teams still need to understand that UXD is not a role, but discipline and culture for the whole Agile environment.
