Answer:
These two anti-patterns are most likely present within the team's retrospectives:
First, Team A members are not acquiring new knowledge and gaining experience. This anti-pattern discourages the team and makes the iteration retrospectives valueless. Team A members are supposed to be learning and gaining experience during the iteration retrospectives. But, once this is not being achieved, the members will likely not value the continued iteration retrospectives.
Two, the iteration retrospectives may become some ritualized formats that never change. There is no current or life in any static object or meeting. The Scrum Master should ensure that the iteration retrospectives are not just her retrospectives but the groups', otherwise, the retrospectives may become mere rituals for the team members to listen up to their master. The Scrum Master must establish a culture of trust so that the team can focus on improvements of the Scrum process.
Explanation:
The role of the scrum master is to ensure that the team lives agile values and principles and follows the agreed processes and practices. She must be able to clear team obstacles and establish an enabling and effective team environment.
Anti-patterns are those obstacles or problems that may arise to prevent the team from achieving its goals, making team members to view the iteration retrospectives as valueless exercises.
Scrum is an agile product development framework that emphasizes team formation, teamwork, and an effective team environment. This ensures that project development is handled in iterative processes with the team members regularly reflecting on their experiences during the daily scrum meetings in order to make adjustments for the achievement of their project goal.
