From obligations to evidence-backed assurance
Supply-chain-security obligations create the need. They may come from regulation, standards, procurement, customer assurance, audit, certification, product acceptance, or internal governance. This handbook helps translate those obligations into practical practices, supplier questions, evidence expectations, and standards-aware implementation options.
Understand the obligation
Start with a regulation, standard, procurement expectation, customer request, audit, certification, product acceptance, or governance obligation.
Apply practical practices
Translate the obligation into supply-chain-security practices, lifecycle controls, responsibilities, and decisions.
Request and verify evidence
Move from supplier assertions to artifacts that can be produced, verified, retained, and reused across the lifecycle.
Common obligations
Supply-chain-security obligations usually arrive through one of these routes. Start with the route that matches the obligation you are facing, then move from obligation to practice, evidence, and verification.
Start with your obligation
Arrive with an obligation, customer request, procurement question, audit task, product-acceptance decision, or governance concern, then choose the next useful route.
| Obligation | Reader question | Best starting route |
|---|---|---|
| Regulation, standard, or compliance expectation | What does this mean for supply-chain security? | Risks & Practices -> 10 Best Practices -> Evidence |
| Customer assurance request | What should we provide? | Use Cases -> Evidence |
| Procurement or acquisition requirement | What should we ask suppliers for? | Procurement & Supplier Assurance -> Evidence Checklist |
| Audit, assessment, or certification activity | What artifacts show controls are operating? | Evidence -> Lifecycle Map |
| Product acceptance decision | How do we know this product is trustworthy? | Product Acceptance -> Identity & Provenance |
| Internal governance or risk review | Where are we exposed? | Risks & Practices -> Lifecycle Map |
Choose your starting point
Route by the decision you need to make, not by sector or standards terminology.
Compliance owner
I need to understand what a regulation, standard, customer request, procurement requirement, audit, or internal governance obligation means for supply-chain security.
Assurance requester
I need to ask suppliers or product teams for useful evidence. What should I ask for?
Assurance implementer
I need to produce, protect, verify, retain, or explain evidence across the lifecycle.
The handbook model
Obligations create the starting point; practices explain what to do; evidence shows whether work is operating; mappings explain where standards and technologies may help.
Obligation
Identify the regulation, standard, customer request, procurement expectation, audit need, product-acceptance decision, or internal governance concern.
Practice
Translate the obligation into risks, controls, lifecycle responsibilities, supplier questions, and operating decisions.
Evidence
Ask what artifacts show whether the practice is operating, whether the claim can be verified, and whether the evidence remains useful after acceptance.
Mapping
Map evidence needs to relevant standards, frameworks, technologies, and verification mechanisms without making any single option the organizing principle.

Use these routes when you arrive with a specific obligation, decision, or assurance task.
Neutral, standards-aware guidance
This handbook explains where public guidance, standards, frameworks, and technologies may fit without treating any single standards body or technology family as the organizing principle.
Technology mappings are implementation options, not mandates. Interpretive mappings are guidance, not formal compliance advice or endorsement.
Open source and evolving
The handbook is developed in the open and will grow with deeper evidence pages, standards mappings, reusable resources, and lifecycle-specific guidance.
