Validated by the vendor is incomplete

A supplier may follow a controlled development lifecycle and test thousands of standard functions. That information can be valuable. But the word validated does not explain whether the evidence covers your intended use, enabled modules, configuration, interfaces, data, roles, procedures, and regulated records.

Accept only the demonstrated scope

Review the supplier’s specifications, test summary, defect list, release process, security and recovery information, and change notifications. Connect accepted evidence to a specific function or risk. A certification describes a management system. It does not prove that your configured approval workflow is suitable for use.

Customer responsibility remains

Document what the supplier evidence supports, its limitations, and the additional customer evidence needed. Test local routing, identity, interfaces, migrated data, signed records, and operating procedures when they matter. Supplier assurance can reduce duplication, but it cannot replace assessment of the customer’s actual regulated use.
