The Scrum Master role may or may not be a full-time job, depending on the environment and the team’s maturity. In environments where Scrum is new or when a new team is developing a new product, the demands on the Scrum Master may be high, requiring a full-time commitment. The Scrum Master must focus on establishing Scrum practices and supporting the team’s development in such scenarios.
In more mature environments where Scrum is well-established, the demands on the Scrum Master may be less intense. In these cases, the Scrum Master might be able to work with more than one Scrum Team or take on additional responsibilities. However, even in these situations, it is crucial to ensure that the Scrum Master can dedicate sufficient time and effort to fulfil their accountability effectively.
