Supply chain and materials evidence
Building the supplier, material and operating evidence that stands up — so a claim can be demonstrated rather than asserted.
Evidence that answers the question being asked
A supply chain makes claims — about origin, composition, performance, content. The evidence either demonstrates those claims or it does not, and the difference matters most at the point someone else asks to see it.
Supplier evidence
What a supplier has actually demonstrated about a material, product or process, and what they have merely asserted — recorded so the difference is visible.
Material and composition records
Bill-of-materials level records for what is supplied, including coatings, layers and minor components that a simple description conceals.
Traceability chains
Supplier, batch, input and output records connected so a specific consignment can be traced and a claim about it substantiated.
Operating evidence
Production, meter and process data that supports what is said about performance, consumption or output.
Traceability and quality are not the same thing
A traceability record tells you where material came from. It does not establish that the material performs to a specification, and treating a traced record as a quality assurance substitutes one kind of evidence for another. Quality is established by testing and qualification against the specific application.
How an evidence programme is built
- What claim are you making?
- The specific statement about a material, product or performance that the evidence has to support — stated precisely before any evidence is gathered.
- What evidence would support it?
- The document, test, record or measurement that demonstrates the claim, and who holds it. A claim without a defined evidence requirement cannot be verified.
- Where are the gaps?
- Which required pieces of evidence exist, which are missing, and which cannot be obtained — because a gap that is known is manageable and one that is discovered late is not.
- How is it kept current?
- Who owns each record, what triggers a review, and what happens when a supplier or a specification changes.
What you receive
Depending on the agreed scope:
- Requirement and evidence register with named owners
- Supplier and material documentation assessment
- Traceability chain design and gap analysis
- Evidence retention and review schedule
- Implementation roadmap with specialist appointments identified
What you bring
- The claims currently being made, and to whom
- Supplier specifications, contracts and correspondence
- Existing test reports, certificates and batch records
- Access to the functions that hold and maintain the records
How the work runs
State the claims
Establish precisely what is being asserted about the material, product or performance, and to whom.
Define the evidence
For each claim, identify the document, test or record that would demonstrate it, and who holds it.
Assess what exists
Review the evidence available, separate what has been demonstrated from what has been asserted, and record the gaps.
Design the chain
Build the record structure that connects supplier, batch, input and output, so a consignment can be traced.
Set ownership and review
Assign each record an owner and a review trigger, so the evidence stays current rather than decaying.
What this looks like by sector
Illustrative examples of the work. They are not client engagements and describe no completed project.
Food & Beverage
Connecting supplier specifications, batch records and test results so a material's composition can be demonstrated rather than described.
Plastics & Packaging
Building a requirement register that records, for each product and market, what applies, what evidence demonstrates it and who owns that evidence.
Manufacturing
Linking production, meter and material records so that a performance or recycled-content claim traces back to the data that supports it.
Recycling & Resource Recovery
Building the input, batch and dispatch records that let recovered material be traced from source through processing to the buyer.
Selected industry applications
The sectors below are the ones whose own pages list this service in their support mapping. Each link goes to that sector's page, which sets out the decisions and the surrounding support. It is a selected set rather than an exhaustive boundary — the service can apply more widely than the hubs currently describe.
If you are still shaping the scope, the project scoping guide walks through the questions that make a brief usable. No email required.
Manufacturing
Connect supplier specifications, material declarations and batch records to customer requirements and supportable product claims.
View the Manufacturing sectorWhat this engagement does not include
- Certification, accreditation or formal assurance of any kind. We build evidence; we do not certify it.
- Legal opinions or determinations on how material or product should be classified.
- Food-safety or chemical-safety determinations, which require qualified specialists and, where relevant, the competent authority.
- Laboratory testing, which is carried out by accredited laboratories.
- Audit or verification services that require an accredited body.
Our role is to establish what evidence is required, assess what exists, design the record structure and set the ownership that keeps it current. Where testing, legal advice or accredited verification is needed, that work must be provided by appropriately qualified specialists under a separately agreed scope.
