Digital Twin as a Service (DTaaS) is emerging as a paradigm that enables scalable, interoperable, and service-oriented implementation of digital twins (DTs). While this approach has the potential to reduce technical barriers to using simulation, a key gap remains: managers and decision makers often lack intuitive tools to interpret and act on DT results. This article proposes a conceptual framework that connects DTaaS with digital tools specifically designed to improve managerial decision-making. Drawing on Product-Service Systems (PSS) logic, the framework structures DTaaS into three levels: the technological engine, the managerial decision process, and a mediating human-centric interface. This approach aims to demonstrate that DTaaS must evolve from a technical infrastructure into an integrated socio-technical system. The result is a continuous "data-insight-action" loop that augments rather than replaces human judgment, ensuring that simulation power translates into accessible and human-centered business value. Indeed, by integrating DTaaS into a decision-oriented framework, this research work aims to bridge the gap between technical infrastructure and human-centered value creation, aligning DT research with the principles of Industry 5.0.
