Final answer:
A Certified ScrumMaster (CSM) serves as a servant-leader to the team, coaches team members in self-organization and cross-functionality, and ensures that Scrum practices are properly implemented.
Step-by-step explanation:
The responsibilities unique to a Certified ScrumMaster (CSM) often entail facilitating the Scrum framework within project teams, particularly in software development. One of the main roles is to act as a servant-leader for the Scrum Team, ensuring that team members can work unimpeded. Another crucial role is to coach the team members in self-organization and cross-functionality. Lastly, a CSM must ensure that all Scrum practices are understood and followed. This involves setting up Scrum ceremonies, such as daily stand-ups, sprint planning meetings, sprint reviews, and sprint retrospectives, and working with the Product Owner to maximize ROI.
