User experience and agile techniques have grown over the last decade. However, there are not many articles that study how the integration of both proposals influences requirements engineering. The objective of this research is to structure the available literature on the integration of agile techniques and user experience in the domain of requirements engineering. A systematic literature review (SLR) was carried out considering duly indexed conference and journal publications. Likewise, the studies found in the four (4) selected databases followed a rigorous study selection procedure. The systematic review recovered a total of 25 primary studies after going through a quality evaluation and revealed the different practices and strategies most used in the requirements analysis integrating agile techniques and user experience. Besides, it allowed identifying the obstacles faced by professionals in requirements engineering. The study carried out concludes that the most used practices in requirements engineering are user stories, low-fidelity prototypes, and person. The literature provides a systematic summary and proposals for frameworks that can be incorporated into agile development projects by integrating user experience.
