Execution Context

This function establishes the foundational blueprint for enterprise software systems by defining high-level architectural patterns, component interactions, and data flow mechanisms. Solutions Architects utilize this process to align technical capabilities with business objectives, ensuring scalability, security, and maintainability before detailed implementation begins. The output serves as the critical reference point for all downstream development activities.

The architect analyzes existing infrastructure constraints and future scalability requirements to determine appropriate architectural patterns such as microservices or monolithic structures.

Specific components, interfaces, and data schemas are defined based on functional needs, ensuring clear boundaries between subsystems and standardized communication protocols.

Risk assessment identifies potential integration points where third-party systems may interact, allowing for proactive mitigation strategies within the design phase.

Operating Checklist

Analyze current infrastructure capabilities and identify future scalability requirements

Select appropriate architectural pattern based on functional and non-functional needs

Define component boundaries, interfaces, and data flow mechanisms

Validate design against security policies and integration constraints

Integration Surfaces

Stakeholder Alignment Workshop

Facilitates discussion on non-functional requirements and business goals to validate architectural assumptions before technical documentation is finalized.

Technical Review Board

Conducts formal evaluation of proposed architecture diagrams and component specifications against organizational standards and security policies.

Integration Planning Session

Maps out specific data exchange mechanisms and API contracts required for seamless interaction between defined system components.
