Positioning of architectural frameworks
The picture below, is the conclusion of a whiteboard discussion an an MVP summit in the US attempting to making sense and positioning the major frameworks that exist today in the enterprise space that are relevant to architecture.
A schema that exists for years is the IEEE 1471 schema below. I find that particularly interesting: simple, complete and to the point. In summary: every system has an architecture whether that architecture is documented (description) or not. That architecture has different angles, according to different viewpoints of different stakeholders of the system (e.g. application architect, infrastructure architect, operations architect, security architect, information architect...) and those different viewpoints require a specific modeling method that works well for their viewpoint.
