However, cognitive biases often lead to planning inaccuracies, particularly during sprint planning. This study investigates whether nudges can improve planning quality in agile teams. In cooperation with an industrial partner developing mechatronic safety systems, tailored nudges were designed and implemented in two Scrum teams. Using a before-and-after design, the effects on story granularity and sprint completion rates were analysed. The results show that, especially in less mature teams, nudges led to a reduction in average story size and an increase in sprint fulfilment. Rather than causing abrupt changes, nudges supported ongoing learning processes and fostered more consistent planning. The study provides initial empirical evidence that nudging can serve as a practical tool to enhance decision-making quality in agile development environments.en1363-91962025World Scientific Publ.agile developmentbehavioural economicscognitive biasdecision architectureinnovation managementmechatronicsNudgingplanning qualityscrumsprint planningstory sizeTechnology::600: TechnologyJournal Article10.1142/S136391962540016XJournal Article
