Agile methodologies have an impact on how organizations carry out Requirements Engineering (RE). In this context, organizations use different kind of agile techniques like artifacts, meetings, methods or roles, but there is a lack of specific guidelines for agile RE. The aim of this paper is to present a modeling language for supporting organizational aspects of agile RE. It allows the visualization of agile RE concepts and their relationships, which can be used to define guidelines for a specific organization, project or domain. The modeling language for agile RE is used in projects in industry and our experiences reveal that it supports organizations in detecting problems and visualizing internal conflicts during the agile requirements phase, among other benefits.
