According to the father of quality, W. Edwards Deming: quality and management are linked… the efficient production of the quality the market expects. Improvement of quality is accomplished by better management of design, engineering, testing and by improvement of processes.
Product Owners and Product Management build the right thing.
Team members build the the thing right: design, build, test, and deploy with built-in quality.
Scrum masters / flow masters (Kanban) improve the processes.
