I currently work as a Solution Architect within a Scaled Agile organization. We also have Product Owners who are in terms of the Company a "higher rank" than the technical oversight group that the Solution Architect's belong to. The technical oversight group sets the standards and looks at process improvement ideas. Occasionally, we run into situations whereas the processes, architecture, etc run up against what the Product Owner wants and causes the Product Owner to override the Solution Architect's even with an established RAA for the company, this still occurs.
Within a Scaled Agile framework, are the Product Owners meant to have their role designed in this fashion since they are the "owners"?
