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.6 This close association to actual projects and initiatives means that solution architecture is the means to execute or realise a technology strategy.
According to Forrester Research, solution architecture is one of the key components by which Enterprise Architecture delivers value to the organization. It entails artifacts such as a solution business context, a solution vision and requirements, solution options (e.g. through RFIs, RFPs or prototype development) and an agreed optimal solution with build and implementation plans ("road-map").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. The Open Group's definition of solution architecture is broader than Forrester's (see aforementioned definition).
According to a 2013 paper published by the Federation of Enterprise Architecture Professional Organizations, solution architecture includes business architecture, information architecture, application architecture, and technology architecture operating at a tactical level and focusing on the scope and span of a selected business problem. 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.89
