Supply Chain Security Worked Examples
Worked examples are the proof layer for the toolkit. They show what stronger evidence looks like in realistic supplier, product, update, vulnerability, and component scenarios.
Use these examples when a checklist or template is too abstract and you need to see how a team can move from a claim to a decision, evidence, verification, gaps, and retention.
Each example supports the same practical workflow: request, review, package, and retain supply chain security assurance evidence.
Route by situation
| Situation | Start with |
|---|---|
| You need to score supplier claims or explain why an answer is not enough. | Weak vs Strong Supplier Answers |
| You need to approve, conditionally approve, remediate, or reject a supplier. | Supplier Onboarding Evidence Package |
| You need to accept, quarantine, reject, or conditionally accept a connected product. | Product Acceptance Package |
| You need to approve, delay, exclude, roll back, or remediate an update. | Secure Update Approval |
| You need to review affected-product analysis, remediation evidence, and customer communication. | Vulnerability Response Evidence |
| You need to move from a component list to provenance, custody, version, and gap evidence. | Component Provenance Example |
Evidence model used in examples
Each scenario follows the same pattern:
threat/failure mode -> decision -> control -> evidence -> verification -> gaps -> retention
Stronger evidence is not just a document. It should show:
- what decision it supports;
- which product, supplier, component, release, service, or lifecycle stage it applies to;
- who produced it and who owns it;
- how origin, integrity, freshness, scope, or consistency can be checked;
- what gaps, exceptions, or risk acceptances remain;
- how long the evidence must remain available and useful.
The examples also label weak, better, and stronger answers using the Evidence Maturity Model, so readers can see the difference between assertion, documented process, produced artifact, verifiable artifact, and lifecycle-retained evidence.
How to use these examples
Use the worked examples alongside the core toolkit:
- Supplier Security Questions for request wording;
- Evidence Checklist for review criteria;
- Evidence Maturity Model for weak, better, stronger, and lifecycle-retained evidence;
- Evidence Package Template for packaging and retaining decisions;
- Technology Options for mechanisms that may help produce, protect, exchange, verify, or retain evidence.
