Hi Julian. From my experience the key to that is an empowered Product Owner who, with a strong product Vision in mind, can work collaboratively with the Scrum team and stakeholders to groom the Backlog back to the point of what is genuinely essential. And the philosohphy of continual delivery really helps here because you are not asking for people to wait a long time for further features - just not "right now". Hope that helps. Thanks, Caroline
