[1] The Open Group's definition of solution architecture, as provided above, is accompanied by the following three from Scaled Agile, Gartner and Greefhorst/Proper.
The Open Group does not recognize the role "solution architect" in its TOGAF skills framework; on the other hand, Glassdoor advertised 55,000 Solution Architect roles in August 2020.
[2] A typical property of solution architecture, in contrast to other types of Enterprise Architecture, is that it often seeks to define a solution within the context of a project or initiative.
[7] Since The Open Group does not recognize a unique Solution Architect role, a relevant link for these mentioned artifacts can be to the Business and Systems Analyst roles.
In contrast, enterprise architecture, which also includes the aforementioned four types of architecture, operates at the strategic level and its scope and span is the enterprise rather than a specific business problem.
