The agile working methods have been developed to meet the needs of flexibility, innovation and increased competitiveness of companies. These methods are characterized by a dynamic and self-directing approach to team management. After covid-19, hybrid work has become an established way of working, this means a combination of remote work and work in the office. Despite this, there is a lack of understanding of the challenges these methods can bring to communication within agile teams. The scrum master can be seen as a project manager within agile teams that work with the scrum methodology. One of the scrum master's most important tasks is to be responsible for communication within agile teams. The purpose of this study is thus to deepen the understanding of the communication challenges that scrum masters can face in a hybrid work environment where team members work from home as well as the office. Through semi-structured interviews with scrum masters, this study delves into experiences of communication challenges and how they deal with these challenges. Based on collected empirical evidence, conclusions can be drawn that scrum masters experience communication challenges linked to, spontaneous communication, digital tools, trust, community and problem solving. The overall conclusion in relation to the study's results is that the scrum masters are well aware of the challenges hybrid work entails and what measures they need to take to deal with them. Although the increasing trend of agile teams working within a hybrid context is relatively new, our results indicate that the scrum masters have undergone a learning process to deal with the communication challenges that have arisen. They have identified challenges with the hybrid way of working and implemented a range of measures to address these challenges. / The agile working methods have been developed to meet the needs of flexibility, innovation and increased competitiveness of companies.
