Abstract-The integration of Agile and User-Centered Design methods is a fundamental condition to improve the quality of software products. However, one of the main problems faced to establish this integration on a day-to-day basis is how to improve communication among the invariably distinct involved teams. We believe that the artifacts involved in the development process could be used to support and increase teams' communication.To better understand this scenario, we performed a systematic mapping study on artifacts and their role in the communication between Agile and User-Centered Design fields. Through the analysis of 56 papers dealing with this specific topic, we present the artifacts used for communication in these approaches and software development events when they are used. The analyzed studies reinforced our beliefs about the importance of artifacts to improve teams' communication.
