Start with the record, not the feature list
Supplier and approved-part information should carry enough context to support engineering decisions without pretending that a product record replaces a procurement process.
That is why the PDM software comparison matrix records only what official material discloses. A blank cell is never treated as proof of absence. It becomes a focused question for a demonstration or technical review.
Define the object. Name the part, file, document, structure, or change record in scope.
02Define its state. Establish who can revise it, who can approve it, and what makes it released.
03Define its connections. Identify BOM, CAD, supplier, ERP, and exchange relationships that matter.
Questions that travel well
Ask vendors to demonstrate the exact point where a record moves from working state to controlled state. Then ask what remains visible to a collaborator, what is logged, and how the relationship is preserved when data crosses a system boundary. The PDM glossary helps keep those questions precise.
Use the evidence state as a boundary. “Documented” means a source names the capability. “Edition-specific” means the source limits the statement. “Not disclosed” means the public materials reviewed here do not make a claim. “Needs verification” identifies material awaiting a usable primary source.
Put the comparison to work
Before a selection meeting, bring the implementation checklist and turn every local constraint into a question. Before a transfer, use the migration checklist to establish the validation plan. These pages are designed to make the next conversation more specific.
