| While a "Source Inspection" typically involves the Inspector personally performing the inspection activities, alternatively, it can consist of the Inspector "witnessing" a supplier's employee performing the inspection activities. Witnessing an inspection activity, rather than performing it, allows the "Source Inspector" to verify that the supplier's employee(s), whether production personnel or quality control inspectors - possess the knowledge, skills, and ability (KSA) to: | While a "Source Inspection" typically involves the Inspector personally performing the inspection activities, there are valid reasons for why an Inspector may instead, choose to "witness" a supplier's employee(s) performing the inspection activities. The most common reason for this is that the Inspector does not have the portable measuring instruments necessary for performing the inspection. While the Customer may require the Supplier to provide the necessary measuring instrumentation, this can introduce a liability (e.g., the Inspector inadvertently damaging the supplier's measuring instrumentation). Witnessing, rather than performing the inspection, greatly mitigates this liability. |

| * verify correct raw material was used (e.g., through associated Material Test Reports, Chemical Analysis Reports) | Witnessing an inspection activity, rather than performing it, also provides some benefits. For example, witnessing the inspection(s) allows the "Source Inspector" to verify that the supplier's employee(s), whether production personnel or quality control inspectors - possess the knowledge, skills, and ability (KSA) to: |
| * verify correct filler material (welding, soldering, brazing) was used | * Read and understand applicable drawings/specifications (e.g., GD&T - Geometric Dimensioning and Tolerancing) |
| * availability and proper use of measuring instruments required for the inspection | * Verify correct raw material was used (e.g., through associated Material Test Reports, Chemical Analysis Reports) |
| * maintain an acceptable accuracy ratio (between the measuring instrument accuracy and the tolerance(s) being measured) | * Verify correct welding/brazing filler material was used (e.g., through associated Certified Material Test Reports) |
| * ensure consistency of any visual inspections with the specifications | * Verify correct soldering material (solder wire, solder paste, solder bar) was used (e.g., lead-free solder vs. lead solder) |
