DO-178C evidence should build itself. Not scramble before SAS review.
One governed system. DO-178C, ITAR, and CMMC evidence produced continuously — not assembled under time pressure before certification or audit.
Commercial aerospace compliance teams carry the most consequential documentation burden in software compliance — and the least engineering support to produce it. DO-178C Software Accomplishment Summary evidence is manually assembled. ITAR component review records are reconstructed pre-audit. CMMC SBOM documentation is a contract delivery requirement most teams treat as a pre-submission sprint.
X-DLM™ makes all of it a byproduct of how your engineering team already works — not an emergency before every certification review or audit cycle.
DO-178C. ITAR. CMMC. Three frameworks. One engineering workflow.
DO-178C software lifecycle data categories that must be planned, produced, verified, and controlled: plans, standards, source code, test cases, and results. Each requires documented traceability to requirements and test objectives.
Software lifecycle data items required for DO-178C DAL A certification — from Plan for Software Aspects of Certification through Software Accomplishment Summary. Each must be traceable, reviewable, and evidence of independence where required.
CMMC Level 2 practices across 14 domains. Every practice requires documented, timestamped, reviewable evidence of implementation — not a policy document. SBOM delivery is a supply chain risk management requirement.
Tolerance for undocumented ITAR-relevant components in a controlled build. Every open-source component with export control applicability requires documented review and approval before inclusion in an export-controlled deliverable.

Evidence that builds during development. Documentation that exists before every review.
- 01
DO-178C lifecycle data — continuous, traceable, DER-ready
X-DLM™ connects Black Duck supply chain findings to Siemens Polarion requirement and test records — so DO-178C traceability data builds continuously during development. Software Accomplishment Summary evidence, Software Conformity Review records, and transition criteria documentation exist before any Designated Engineering Representative review. Compliance teams review and approve — they do not reconstruct.
- 02
ITAR component review records — before export control audit
Black Duck identifies every open-source component with ITAR-relevant export control applicability. X-DLM™ routes each flagged component into a Polarion approval workflow with owner, review date, disposition, and approval chain. Component review records exist before any DoS Bureau of Political-Military Affairs or DoC Bureau of Industry and Security review. Compliance teams document export control decisions in a governed system — not a spreadsheet.
- 03
CMMC evidence — SBOM, vulnerability response, and supply chain risk management
Black Duck generates machine-readable SBOM in SPDX and CycloneDX for CMMC supply chain risk management evidence and DoD contracting officer delivery. X-DLM™ links every SBOM component to Polarion release records and routes every vulnerability advisory into a governed response workflow. CMMC Level 2 evidence across Incident Response, Risk Assessment, and System and Communications Protection domains builds from the same engineering workflow.
- 04
Audit preparation — what exists versus what needs to be assembled
The difference between a compliant commercial aerospace software company and one that scrambles before certification is not the amount of work done — it is when the evidence was created. X-DLM™ ensures DO-178C data, ITAR review records, and CMMC documentation exist continuously during development. When a certification authority, export control reviewer, or C3PAO assessor asks for evidence, it is already in Polarion — not being assembled the week before.

X-DLM™ turns Black Duck software supply chain intelligence into Siemens Polarion work items, requirements links, approvals, escalation paths, and continuously maintained evidence.

Polarion provides the lifecycle system of record for requirements, tests, approvals, traceability, workflow automation, audit evidence, and regulated software delivery.
Black Duck Software Composition Analysis
Black Duck identifies open source and third-party components across source, binaries, containers, firmware, snippets, AI-generated code, and C/C++ environments without package managers.
Aerospace and defense companies answer to more than one framework.
CMMC 2.0 is the floor, not the ceiling. DO-178C, NIST SSDF, ITAR/EAR, and IEC 62443 run simultaneously — each with its own evidence requirements, its own audit path, and its own consequence for non-conformity.
