Typical outputs
FHAPSSASSASafety traceability review
Training & working sessions
From standard text
to project decisions.
Modules combine standards context with the documents, reviews and evidence choices teams make during delivery.
Analysis methods
FHA, FTA, FMEA and common-cause techniques.
PSSA to SSA
Architecture assumptions, mitigations and verification evidence.
Development integration
How safety results drive ARP 4754A, DO-178C and DO-254 assurance.
Instructor assignments and any claimed program history are provided only after internal approval and verification.
Engagement scoping
Information that makes the first review useful.
No compliance outcome is promised from a website form. Scope begins with the program facts and evidence that can actually be reviewed.
Applicable basis
Standard revision, authority or customer basis, assurance level and agreed means of compliance.
Lifecycle state
Current milestone, approved plans, baselines, open findings and target review date.
Requested boundary
Training, gap analysis, document review, evidence recovery or audit-readiness support.
FAQ
Questions before the first workshop.
What assigns a DAL?+
Development assurance levels are informed by the system safety process and failure-condition classification, then allocated through the system architecture.
Can existing safety analyses be reviewed?+
Yes. A review can focus on assumptions, completeness, consistency, traceability and alignment with the current architecture.
