Two Suppliers Can Still Share One Point of Failure
Names do not measure real alternatives
A procurement report listing two suppliers does not establish two independent alternatives. If both source a critical item from one factory, an upstream disruption may affect both. Executives should ask what shared production or logistics dependencies are known and verified, rather than equating different invoice names with diversification.
Business Queensland recommends knowing suppliers and reducing sole-source reliance. Australia’s Choosing secure and verifiable technologies guidance also highlights upstream single-supplier dependency. These are risk-management perspectives, not a legal requirement that Thai companies maintain a particular number of suppliers.
Start with items whose absence stops work
Ask operations to identify materials, parts or services whose absence prevents delivery, then link item codes to suppliers and known production sources. A cheap input can stop high-value work, so purchase value alone should not determine priority. Record data owners and verification dates to avoid relying on obsolete relationships.
Mark undisclosed information as unknown rather than proof of independence. If detailed information is needed, define its use and confidentiality under the relevant agreement. Do not collect unnecessary trade secrets; the aim is to understand dependencies affecting your own delivery.
A backup must meet actual operating needs
Suppose a factory buys a part from suppliers A and B but discovers a shared source. Supplier C offers a similar item that has not passed quality testing. Report C as an alternative awaiting qualification, not immediately available replacement, and identify who authorizes testing and accepts results.
Compare sourcing time, qualification time, supply capacity and switching costs together. Extra stock ties up cash and may deteriorate; additional suppliers bring quality-control and contractual work. Present alternatives with assumptions instead of using “backup available” as a substitute for tradeoff analysis.
End the report with decisions and owners
Use one row per critical item showing dependencies, confidence, usable stock, confirmed replacement lead time, impact and required decisions. Separate estimates from verified information. When timing changes, update delivery and cash implications instead of retaining an unchanged risk score.
Set review triggers such as a changed production source, quality decline or sales exceeding existing supply capacity. Bring purchasing, stock and constraint data to Kerwin & Vance for discussion of management reporting and internal controls within its actual services. The aim is informed choices and explicit accepted risks, not a guarantee against disruption.
