Which of the following in the Enterprise Continuum is not an example of an external architecture or solution artifact?

In the context of the Enterprise Continuum, the correct answer points to deliverables from previous architecture work, as they do not represent external architecture or solution artifacts. The Enterprise Continuum is a framework designed to help organizations understand and manage their architectural assets as they evolve and adapt to changing needs. It categorizes architectural artifacts into different types, distinguishing between internal and external concepts.

Deliverables from previous architecture work are primarily internal to the organization. They reflect the outcomes and insights gained from earlier architectural efforts tailored to meet specific business needs. While they may inform future projects, they do not represent an architecture or solution that is generalized or applicable to a broader context outside of the organization, which is a characteristic of external artifacts.

In contrast, the TOGAF Technical Reference Model (TRM), IT-specific models like web services, and the ARTS data model represent frameworks or standards that can be applied across various contexts, thereby qualifying them as external architecture or solution artifacts. These artifacts are designed to be reusable reference models that guide and inform current and future architecture decisions within the enterprise and beyond.
