What is the main reason for the Scrum Master to be at the Daily Scrum?

The primary reason for a Scrum Master to be at the Daily Scrum is to ensure that the Development Team is able to hold the meeting effectively and to support the team in adhering to its Scrum practices. The Daily Scrum is primarily a meeting for the Development Team to inspect their progress toward the Sprint Goal and to adapt their upcoming work accordingly. The Scrum Master’s role is to facilitate this process without taking over or leading the discussion.

By being present, the Scrum Master can help remove any obstacles that might impede the Development Team's ability to conduct their meeting effectively. The focus is on empowering the team to self-organize and manage their own process rather than directing or dominating the meeting. This support ensures that the Scrum framework is respected and that the team is working collaboratively towards their goals.
