An anti-pattern is a behavior that seems helpful but actually undermines Agile principles. In the context of Iteration Retrospectives, one anti-pattern for Scrum Masters or Team Coaches is focusing only on what to improve and not on what to preserve.
Effective retrospectives are balanced-they highlight both what went well and what can be improved. Recognizing and reinforcing successful practices helps the team sustain productive behaviors while targeting specific areas for change. Ignoring positive aspects can lower morale and overlook practices that contribute to success.
From SAFe guidance:
"Teams use the retrospective to discuss what went well, what didn't, and what actions to take. Recognizing what to preserve reinforces effective team habits and strengths." Therefore, the correct answer is B. They focus only on what to improve and not what to preserve, as this behavior disrupts balanced reflection and continuous improvement.
