Inspection works best when findings connect across the project lifecycle. A material traceability gap during production should be visible at release. A shipment defect should be traceable back to process history. Corrective action should close the cause, not just the symptom.
We do not treat audits, inspections, and corrective actions as isolated events. Each gate produces evidence that informs the intensity and focus of the gate that follows, so risk is compounded downward, not rediscovered late.
Build an inspection planAssess supplier capability, QMS controls, factory readiness, certifications, equipment, staffing, and risk before production begins.
Monitor incoming materials, process parameters, workmanship, in-process testing, traceability, and nonconformance handling.
Apply agreed sampling and acceptance criteria before shipment, with clear pass, hold, or reject disposition supported by evidence.
Confirm corrective actions and receiving condition, then feed lessons back into supplier controls and future inspection intensity.
The depth of each gate flexes with factory risk, module technology, and how much commercial exposure rides on the lot.
Before a purchase order is exposed to risk: QMS maturity review, capability and capacity check, equipment and calibration status, staffing and competency, certification validity, and a documented risk rating that sets the surveillance intensity for everything that follows.
During active production: BOM and work-instruction verification, process-parameter witnessing, in-line and in-process testing, workmanship review, traceability sampling, and disposition of nonconforming product, the point where drift and substitutions are caught early.
At shipment: AQL sampling against agreed acceptance criteria, visual inspection, EL image assessment, flash/IV verification, hipot and continuity, labeling, packaging, and pallet condition, resolved into a clear pass, hold, or reject decision you can act on.
After the fact: corrective-action review and closure verification, receiving-condition inspection after transport, and a feedback loop that adjusts supplier controls and future inspection intensity based on what actually happened.
Remote paperwork misses what a person standing at the line can see. Our inspectors are on site at the moments that carry the most risk, tablet in hand, checking real product against real acceptance criteria and recording exactly what they find.
That is how a shipment problem stays traceable back to a process cause, and how a corrective action gets verified instead of just promised.
Talk through your project
For most domestic engagements, scoping is completed quickly and on-site work is scheduled around your production or shipment window. International oversight is coordinated with the factory calendar.
We work to your specifications, approved quality plan, and AQL criteria wherever they exist, and reference applicable IEC or ISO requirements. Where criteria are missing, we can help define defensible, project-appropriate acceptance standards.
An executive summary with a clear disposition, risk-classified findings, supporting objective evidence (photos, serials, process data, EL/IV results), and explicit corrective-action and closure requirements, written to make the next decision easier.
Usually, yes. Certification proves a module design passed a test at one point in time. It does not confirm that the specific lot heading to your project was built with the approved materials and process. Independent inspection checks the actual product you are paying for, not the design on paper.
Yes. Being US-based is an advantage here. We can reach domestic module lines quickly, coordinate in your time zone, and support the quality and documentation that domestic-content projects increasingly need, without the delays of an overseas-only inspection firm.
Yes. While Sisoko is based in Columbus, Ohio, oversight of overseas manufacturing can be coordinated around the factory's production and shipment schedule so lots are witnessed and released at the right moment.
Yes. Sisoko holds no manufacturer ties and works only for the party commissioning the inspection. Findings are reported objectively, with the evidence attached, so there is no conflict of interest.
