See single-source and concentrated materials, score the exposure, and weigh alternatives with their caveats.
What the analysis reads
The analysis reads the suppliers engaged for a passport, what they are recorded as able to provide, their evidence state - declarations answered, certificates expired, conflicts open, documents readable - and the same risk formula the supplier page uses.
Because it depends on recorded capabilities, a supplier whose capabilities are not on file cannot be proposed as an alternative. Record capabilities first.
Exposure and the resilience index
Exposure is reported per material: whether there is a single source, how concentrated the supplying countries are, whether the material only appears upstream, and whether any supplier could be attributed at all.
The resilience index starts from a full score and itemises every deduction with its reason, so a low score is explainable rather than mysterious.
Alternatives, blockers and conditions
Substitution candidates are drawn only from suppliers already recorded as able to handle the material, and eligibility is decided before score - a technically ideal supplier is not a candidate if they cannot do the work.
Evidence that contradicts use is a blocker: an expired certificate, an open cross-reference conflict. Missing evidence is a condition to close rather than a verdict. Every recommendation also lists what switching would not fix - the carbon footprint until new data arrives, upstream exposure, unchanged country concentration, and any qualification the platform cannot grant.
Decisions
Decide shortlist, reject or adopt, with a reason; a rejection or adoption without one is refused, and a blocked candidate cannot be adopted.
Adopting can open a supplier data request so the loop closes in the usual workflow. The platform never rewrites a passport's supply chain on your behalf.
One rule keeps the analysis honest: an unanswered request is a question, not a supply relationship. Adopting a candidate opens a request, and until that supplier answers they are still reported as under evaluation rather than becoming the incumbent.
Assessments and the portfolio
Issuing an assessment stores an immutable artifact with a reference, the exposure, the alternatives and the index, exportable as CSV and revocable. Alternatives keep their decisions across re-assessments and are marked cleared rather than deleted when they are no longer proposed.
The portfolio view lists materials at risk and the weakest passports so you can work on the biggest exposure first.
Screen-by-screen reference
These pages were checked in the organization console on 8 October 2026 using an isolated sample organization. Controls can differ by role, plan, record state and configured providers. Each page below explains its purpose, a practical workflow, the visible controls and what to verify afterward.
Sourcing (/sourcing)
The sourcing view highlights concentrated or single-source materials and models alternative supplier decisions.
Use portfolio risk and material concentration to choose a product whose dependency deserves review. The passport state explains which supplier or material is a blocker and what a substitution candidate would change. Request missing supplier evidence before treating an alternative as available; a simulated candidate does not edit the actual product record.
A proposed substitute does not silently rewrite the product's supply chain.
Controls and options
- Read Portfolio and Materials at risk for affected passport counts and blocker patterns.
- Choose a passport and Show the state to inspect its dependency graph and resilience deductions.
- Record a substitution candidate only after checking its blockers and what it would not fix.
- Open a supplier request for evidence before treating a candidate as available.
