Beyond architecture diagrams
A target architecture cannot govern a program on its own. Transformation needs a way to resolve trade-offs, record exceptions and check whether delivery still reflects strategic intent.
Make the decision inspectable
A Design Authority can use a common decision record: the business question, accountable owner, options, dependencies, security implications, decision and conditions. This keeps review focused on choices and consequences.
Close the loop
Every conditional approval needs an owner and a verification point. Without that loop, architecture governance risks becoming a meeting rather than a control discipline.
