Retrium is a comprehensive software tool designed to facilitate and improve retrospectives for Agile teams. Retrium was developed to address the challenges Agile teams face during retrospectives. These challenges include ensuring active participation, maintaining engagement, and deriving actionable insights that lead to continuous improvement. Retrium aims to make the process of reflecting on past work more structured, engaging, and effective. Retrium offers a variety of retrospective techniques and templates, such as Start/Stop/Continue, Mad/Sad/Glad, 4Ls (Liked, Learned, Lacked, Longed For), and many more. These templates help teams choose the right format for their specific needs and contexts.
