According to the TOGAF standard, the two statements provided refer to different scopes within which architecture can be developed:
Groups of countries, governments, or governmental organizationsworking together typically align with broader, often international, scopes of architecture that transcend individual enterprise boundaries.
Partnerships and alliances of businessesworking together, such as a consortium or supply chain, refer to collaborative efforts that can define architecture at a scope involving multiple enterprises.
In both cases, the term "Architectures Scopes" is appropriate because it reflects the varying levels and contexts in which architectures can be defined, ranging from single business units to collaborative inter-organizational efforts.
