Which of the following, if observed in reviews and tests, would lead to problems (or conflict) within teams?

When testers and reviewers communicate defects as criticism against individuals rather than focusing on the software product itself, it creates a toxic environment that can lead to conflict within teams. This behavior can lead to defensiveness among team members, disrupt collaboration, and hinder open communication. Instead of promoting a culture of learning and improvement, this approach fosters blame, reducing morale and possibly leading to a breakdown in cooperation.

A focus on the product, using constructive feedback, allows teams to address issues collaboratively and learn from each defect found, strengthening the overall quality of the software. Such an atmosphere encourages an open discussion about issues without the fear of personal attack, which is crucial for effective teamwork and continuous improvement. By maintaining a healthy, constructive approach to discussing defects, teams can work more effectively toward common goals.
