The critical need for employee wellbeing in organizations calls for a comprehensive approach integrating positive psychology, positive organizational scholarship (POS), and implementation science and relevant pedagogical theories. This Capstone presents a transversal analysis of the scaling problem in wellbeing initiatives and proposes an innovative solution: "Positive Organizational Wellbeing Implementation Science." This framework provides a multi-faceted, systematic approach to scaling wellbeing initiatives effectively across diverse organizational contexts. It encapsulates the whole cycle of initiative development and deployment, from identifying potential interventions to executing and continuously improving them. The study uses a descriptive-analytical design, drawing from literature reviews and expert analysis. Key aspects of the framework - including the source, structure, scope, and synchronization of wellbeing content; training and pedagogy methods; organizational top-down commitment and bottom-up engagement; and robust infrastructure and continuous refinement - are examined in depth, with a particular focus on the role of content. The analysis demonstrates that a well-structured, comprehensive approach can lead to successful, scalable wellbeing initiatives. Furthermore, the study underscores the importance of scientific, evidence-based methodologies in developing and deploying wellbeing initiatives. The implications of this study carry significant relevance for the employee wellbeing industry, providing a robust model for creating and managing scalable initiatives.
