High Level Solutioning

Solution architecture is a practice of defining and describing an architecture of a system delivered in context of a specific solution and as such it may encompass description of an entire system or only its specific parts. Definition of a solution architecture is typically led by a “solution architect.”

A Solution Architecture typically applies to a single system or system release, assisting in the translation of Features into a solution vision, and high-level business and/or IT URD.

Solution architecture is one of the key methods by which enterprise architecture delivers value to the organization. Solution architecture activities take place during solution ideation, solution design, and solution implementation. During ideation, solution architecture establishes the complete business context for the solution and defines the vision and requirements for the solution. During design, solution architecture elaborates potential options. It selects the optimal option, which then becomes the input for roadmap for the selected solution. During implementation, solution architecture communicates the architecture to the stakeholders, and guides the implementation team.

The relationship between enterprise architecture and solution architecture is generally well understood. 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. Consequently, enterprise architecture provides strategic direction and guidance to solution architecture.
