Safety Assurance for High-Consequence Systems

Connect hazards, controls, claims, and evidence in one governed assurance thread.

Core Safety Assurance Capabilities

Hazard and Risk Management

Capture hazards, consequences, and mitigations with structured risk records that support lifecycle updates and governance checkpoints.

Assurance Argument Modeling

Build and maintain safety arguments using GSN-style structures so claims, strategies, context, and evidence remain explicit and reviewable.

Traceable Evidence Linkage

Link safety claims and controls to requirements, verification outcomes, and supporting evidence for defensible assurance cases.

Assurance Change and Delta Review

Compare safety argument and hazard-state changes between baselines to identify assurance-impacting deltas early.

Functional Workflow Across Safety Modules

  • Register hazards and risk controls with accountable ownership and lifecycle status tracking.
  • Develop safety arguments and maintain relationships between claims, assumptions, and supporting rationale.
  • Attach evidence and verification outcomes to assurance nodes to support review board confidence.
  • Review unresolved hazards, weak claims, and evidence gaps before stage-gate approvals.
  • Publish controlled safety assurance packs for audits, cert reviews, and release decisions.

Baseline and Audit Readiness

Track safety argument maturity and include assurance artifacts in controlled baseline and evidence package workflows.

Safety Thread Continuity

Keep hazards, claims, and evidence connected through assurance workflows so safety intent stays aligned with delivery reality.

Decision Support

Surface risk posture and assurance status so governance boards can make timely, evidence-based acceptance decisions.

Assure Safety With Traceable Confidence

OpenSESA safety assurance management gives engineering and assurance teams a unified environment for hazard control and argument-backed release readiness.
