Service Design is a comprehensive and collaborative design approach for creating value for all stakeholders. Service Design includes several methods and tools for the improvement of a new or an existing service. The implementation of Service Design into software development has been only partially studied. Likewise, research regarding the benefits and challenges concerning the utilization of Service Design precisely in software development is rather deficient. The aim of this study was to experiment applying Service Design methods and tools into software development through a pilot project carried out in a Finnish software development company. This research presents possible benefits and challenges that implementing Service Design into software development may have. In addition, critical factors to be considered while implementing Service Design are proposed.
