Which of the following in the Enterprise Continuum is an example of an internal architecture or solution artifact that is available for re-use?

The most suitable choice that exemplifies an internal architecture or solution artifact available for re-use within the Enterprise Continuum is the deliverables from previous architecture work. These deliverables are created during architecture development and can include documents, models, templates, and more. Because they have been specifically tailored and refined for the organization, they represent accumulated knowledge and solutions that can efficiently address similar future requirements.

Leveraging these deliverables enhances the efficiency and effectiveness of the architecture development process, as they provide proven references and designs that can be reused rather than starting from scratch. This is a foundational principle of the Enterprise Continuum: to maximize the reuse of existing architecture assets to streamline project efforts and reduce redundancy.

In contrast, the other options listed, while valuable, do not fit the definition of internal architecture artifacts to the same extent. Industry reference models and patterns are external and general best practices rather than specific internal solutions. The TOGAF Technical Reference Model (TRM) is a framework designed to provide standards and concepts but is also not a tailored internal artifact. The ARTS data model, though useful, refers to a specific external standard that is not exclusively owned by or unique to the enterprise's internal architecture practices.
