The development culture needs to shift from relying on QA members to find bugs to a quality-focused approach that involves all team members. This requires top-down support and empowerment of developers and Scrum Masters, who can guide the team towards quality by enforcing unit tests and documenting acceptance criteria. Peer pressure can be created through a strong developer champion who drives change and encourages others to follow suit. Team members can help by educating their peers about the cost of bugs, using metrics from bug tracking systems to drive improvement, and presenting data that shows the benefits of a quality-focused culture.
