Scrum Master Service to the Organization

From the Scrum guide

The Scrum Master serves the organization in several ways, including:

  • Leading and coaching the organization in its Scrum adoption;

  • Planning Scrum implementations within the organization;

  • Helping employees and stakeholders understand and enact Scrum and empirical product development;

  • Causing change that increases the productivity of the Scrum Team; and,

  • Working with other Scrum Masters to increase the effectiveness of the application of Scrum in the organization.

How much of this rely truly on the SM shoulder? How much on the Agile Coach? What's your experience? As SM are you practicing this part of your duties?
