FlyNow — Verification in Teamcenter

What this is

The VCRM, materialized as a live thread

Requirement → Verification → Evidence, in the tool — not a spreadsheet.

The acquisition thread produced a paper Verification Cross-Reference Matrix (Section 4 of the SRD). Here that matrix is materialized in Teamcenter with the native V&V objects the instance actually deploys: for each of the 51 QX-250 requirements a method-specific verification requirement (IAV0InspectReqmt / IAV0AnlysisReqmt / IAV0MeasureReqmt) is created and linked to the requirement with the native verification trace link (IAV0VerificationTL) — the method is carried by the object type, not a made-up property. Three structural verifications also link to the NX frame (TC Item 038756), so the thread reaches the live CAD.

Native V&V. These are the real deployed objects, not stand-ins: IAV0*Reqmt verifications, Crt0VerifRequest verification requests, and Att0ParameterSet acceptance parameters, joined by the native IAV0VerificationTL relation. The whole matrix regenerates from the live Teamcenter state.

Parameter → Verification → Result → Pass/Fail

The acceptance criteria are no longer buried in prose — they're structured parameters, each with a measured value and a result, all in Teamcenter.

Every quantitative requirement now carries an acceptance parameter (name · operator · target · unit, e.g. Loss-of-thrust rate ≤ 2×10⁻⁴/hr), trace-linked to the requirement. Each of the 51 verifications produced a Result carrying the measured value from the real design evidence (MADe, Amesim, NX, Capital, bench, flight), and the 51 verifications are grouped into 5 Verification Requests by method — the execution/campaign layer. The QX-250 passes 30 of 51.

Native, end to end. Acceptance parameters are native Att0ParameterSet objects, the 5 campaigns are native Crt0VerifRequest objects, and each verification is a native method-typed IAV0*Reqmt — all trace-linked with IAV0VerificationTL. The measured values and results come straight from the design evidence, and the matrix regenerates from the live Teamcenter state.

The real objects

Native V&V, not stand-ins

The instance ships Siemens' verification accelerator — so the thread uses the genuine types.

QX-250 Verification Program structure in Active Workspace: one root, five verification-request campaigns, 51 verifications — **The whole verification program in one structure** — live Active Workspace. Root REQ-000136 · QX-250 Verification Program (Type: **Verification Requirement Revision**) contains the **5 verification-request campaigns** — Inspection, Analysis, Demonstration, Test-Bench and Flight-Test, each tagged with its native Crt0VerifRequest id (TC 039004–039008) — and every campaign nests its **native IAV0*Reqmt verifications** (Inspection expanded here, 1.1–1.16). All 51 verifications sit under one tree; the document pane renders the same hierarchy as a numbered specification.

IAV0*Reqmt — verifications

One per requirement, typed by method: IAV0InspectReqmt (16), IAV0AnlysisReqmt (13), IAV0MeasureReqmt (test) and IAV0VerifReqmt (demo). Linked to the requirement with IAV0VerificationTL.

Crt0VerifRequest — requests

5 native verification-request packages, one per method campaign, each linked to its verifications with IAV0VerificationTL.

Att0ParameterSet — parameters

30 native acceptance-parameter sets, one per quantitative requirement, carrying the target and the measured value from the design evidence.

Native IAV0 verification object REQ-000109 open in Active Workspace — Live Active Workspace — the native verification object REQ-000109 · “Verify REQ-REL-003 by Analysis”. Note the header **Type: Simulation Requirement Revision**, the display name of the deployed IAV0AnlysisReqmt type — a genuine verification object from Siemens' V&V accelerator, trace-linked to reliability requirement REQ-REL-003, not a generic stand-in.
