This document outlines a master's thesis that designed a digital service concept for a professional business service organization called Työeläkelakipalvelu. The thesis sought to address organizational challenges, facilitate knowledge sharing, and improve customer experience through a service design approach. Empirical data was collected through expert interviews and focus groups to understand stakeholders and users. Various service design tools and processes were used to generate concepts, including stakeholder mapping, affinity diagrams, SWOT analysis, feature trees, prototyping, and use cases. The resulting service concept aims to create value for both the service provider and users by serving as a platform to enable exchanges between staff and customers in the field of earnings-related pensions.
