01 · ARGUMENT
Build the assurance case
Casewright assembles the GSN safety argument from your requirements: top claim, sub-claims, and the evidence each rests on.
ISO/PAS 8800 · Clause 8 · Evidence readiness
Your requirements already live in Jama, DOORS, or Polarion. Casewright turns them into a structured assurance argument — and shows you the gaps an OEM reviewer will flag, before they do.
Casewright is a workflow tool for engineers. It does not make safety determinations or reviewer decisions.
Clause 8
Assurance argument, structured for you
Evidence-Readiness Review

What it does
01 · ARGUMENT
Casewright assembles the GSN safety argument from your requirements: top claim, sub-claims, and the evidence each rests on.
02 · EVIDENCE READINESS
Every branch gets a structured readiness review. Evidence that's present but not yet ready surfaces instantly — a finding requirements tools don't produce on their own.
03 · GAPS
An ordered gap list in the language an OEM reviewer uses, so you close holes before the review, not after a rejection.
Integration model
Casewright imports requirements, ODD statements and verification records over ReqIF from Jama Connect, IBM DOORS Next or Polarion. Your system of record stays where it is, and keeps its baselines, traceability and change control.
What comes back is the work product those tools do not produce: an assurance argument structured to ISO/PAS 8800 Clause 8, an evidence-readiness review per branch, and a gap list written the way an OEM reviewer writes findings.
No migration, no duplicate requirement set, no second source of truth to reconcile at the safety review.
