Emotions are part of our everyday life and are known to impact cognitive skills, thus influencing job performance. This is true also for software development, an intellectual activity requiring creativity and problem-solving skills that are known to be influenced by affective states. In particular, early recognition of negative emotions, such as stress or frustration can enable just-in-time intervention for developers and team managers, in order to prevent burnout and undesired turnover. In this talk, I will provide an overview of recent research findings on developers’ emotions and their relationship with self-assessed productivity. Next, I will argue in favor of the emergence of tools to support developers’ emotion awareness at the individual and team level to improve productivity, resilience to failures and wellbeing.
