Systems Architecture
Define, assess, and evolve architecture with controlled, standards-aligned workflows.
Core Systems Architecture Capabilities
Viewpoints and View Consistency Management
Define and maintain coherent architecture viewpoints and views so stakeholder concerns are represented consistently across the architecture baseline.
Logical and Physical Decomposition with Allocation
Develop architecture structures from logical concepts to physical realization and allocate functions and responsibilities across system elements.
Architecture Decision Rationale and Evidence
Capture architecture decisions, rationale, assumptions, and supporting evidence to preserve intent and support governance reviews.
Alternative Evaluation and Trade-Study Support
Compare candidate architecture alternatives against defined drivers, constraints, and quality attributes before selecting a preferred solution.
Interface Architecture Boundary Definition and Control
Define internal and external interface boundaries, interface characteristics, and controlled interface changes across architecture elements.
Trace Continuity to Requirements and V&V
Maintain architecture trace links to requirements and verification and validation artifacts so design intent and evidence remain connected.
Baseline Governance and Change Impact Analysis
Control architecture baselines, evaluate impacts of proposed changes, and govern evolution with clear ownership and decision records.
Architecture Conformance and Completeness Assessment
Assess architecture coherence, completeness, and conformance against defined criteria before downstream commitments and reviews.
Systems Architecture Lifecycle Workflow
- Establish architecture context, stakeholder concerns, drivers, and constraints.
- Develop candidate logical and physical architectures with explicit interface boundaries.
- Run trade studies and evaluate alternatives against defined decision criteria.
- Baseline selected architecture and govern controlled updates with impact analysis.
- Assess conformance and completeness as architecture evolves through delivery.
Build and Evolve Architecture with Confidence
OpenSESA gives systems engineering teams one controlled environment for architecture definition, trade evaluation, baseline governance, and conformance assessment.
