What level of source inspection involves the least oversight of supplier/vendor quality?

The level of source inspection that involves the least oversight of supplier or vendor quality is characterized as having no source inspection. When there is no source inspection, it indicates that there is no direct oversight or evaluation conducted by an inspector during the manufacturing or assembly processes at the supplier’s facility. This means that the responsibility for quality assurance is left entirely to the supplier or vendor without any intervention or verification from third-party inspectors.

In contrast, other levels of source inspection, such as final, intermediate, or resident source inspections, involve varying degrees of oversight where inspectors are engaged at different stages or continuously present at the supplier’s site. This ensures that quality control measures are actively monitored, which does not occur with no source inspection at all. Consequently, relying solely on the supplier’s own quality practices may lead to increased risks regarding the integrity and reliability of the produced items.
