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 · Clause 9
Your requirements already live in Jama, DOORS, or Polarion. Casewright turns them into a defensible assurance argument — and tells you where it will fail assessment, before the OEM's assessor does.
Clause 8
Assurance argument, built for you
Clause 9
Sufficiency, scored automatically
ReqIF
Works with the tools you own
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 · SUFFICIENCY
Every branch gets a sufficiency score. Weak and missing evidence surface instantly.
03 · GAPS
An ordered gap list in assessor language, so you fix holes before assessment, not after 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, a sufficiency score per branch, and a gap list written the way an assessor writes findings.
No migration, no duplicate requirement set, no second source of truth to reconcile at the safety review.
