End-to-End Engineering Thread
OpenSESA connects planning, architecture, requirements, verification, safety, baselines, and readiness in one workflow.
Open Core for Systems Engineering
OpenSESA Core is FREE, open source, and MIT licensed. Use, modify, self-host, and redistribute it with no core license fee. View MIT License.
Core Freedom
Use the core freely across internal programs, supplier ecosystems, and customer-facing commercial work.
Scalable Architecture
Scale from single-team projects to large programs with an architecture built for growth.
Modular Delivery
Add the modules your project requires, when you need them, without reworking your engineering foundation.
OpenSESA is modular by design, so teams can add the capabilities each project requires across mission, lifecycle, and compliance contexts.
Purpose
Provide one governed digital thread for planning, building, verifying, and releasing complex products with full lifecycle traceability.
Who It Is For
Cross-functional program teams, including engineering, product, quality, safety, operations, suppliers, and compliance stakeholders.
What You Get
Shared visibility, end-to-end traceability, controlled change, faster decision cycles, and release confidence without fragmented tooling.
Turn Requirements Into Delivery
Define requirements, run reviews, and keep trace links to architecture and verification. Move faster with audit-ready control.
Plan, Run, and Prove V&V
Build V&V plans, track evidence, and monitor coverage in one place. Keep results linked to design and change decisions.
Align Design and Integration
Coordinate design, interface ownership, and integration readiness in one flow. Reduce rework by exposing changes early.
- System and subsystem integration views
- Interface definition and change visibility
- Integration readiness and issue tracking continuity
Make Release Decisions Faster
Track readiness, approvals, and go/no-go gates in one dashboard.
Keep Safety Cases Connected
Build GSN arguments, track hazards, and link evidence to requirements and verification.
- GSN goals, strategies, and solutions
- Hazard register with mitigation visibility
- Evidence status aligned to safety outcomes
Core Modules
