Designing great services and offerings is the essential promise of Service Design, but bringing services to life involves making them part of much larger experiences. This means transforming the way businesses work, and realigning the various moving parts of enterprise ecosystems. The complex and volatile nature of such systems quickly becomes overwhelming, with brands, processes, culture, technology or touchpoints being just tiny parts of the puzzle. In this short talk we are going to advocate for the integration of Business Architecture approaches to model potential futures, as a means to put a Service Design initiative into action. We will illustrate this with examples from our work with the United Nations.
