In this poster paper, we propose and demonstrate an architectural framework for service Management and Orchestration (M&O) in Sixth-Generation (6G) communication systems. This architecture was designed by the Hexa-X project, which is a European flagship project dedicated to developing a vision and  technological enablers for 6G. To provide a comprehensive and  high-level description, we consider three views: (i) Functional  View; (ii) Structural View; and (iii) Deployment View. We first  discuss 6G service M&O before delving deeper into each view.
