Abstract: The concept of Total Team Quality represents a transformative approach to quality management within Scrum teams, moving away from traditional siloed testing and quality assurance methods toward a more integrated, collaborative model where quality becomes everyone's responsibility. This comprehensive analysis demonstrates that when properly implemented, Total Team Quality practices lead to significant improvements in both product quality and team velocity, with case studies showing up to 40% reduction in User Acceptance Testing (UAT) defects and duration alongside 20% increases in velocity. The approach centres on shift-left testing principles, shortened feedback cycles, reduced work-in-progress limits, and the cultivation of high-performing teams where quality is embedded into every phase of the development process rather than being an afterthought or separate activity.
