Quality control vision inspection
Looks at images or video of physical items moving through a production, packing, or fulfillment process, and flags items that fail the firm's quality criteria: damaged packaging, missing components, incorrect labels, manufacturing defects. Sits alongside human QC rather than replacing it: the pattern handles the high-volume routine cases so humans can focus on the genuinely ambiguous ones. Different shape from the other D patterns because it processes images, not text or structured records, and because the kill metrics are different (false negatives let bad product through; false positives slow throughput). Used in light manufacturing, fulfillment, and food production.
Requirements describe capabilities the pattern needs in your environment, not the vendors you must buy. Any system that fills a requirement satisfies it — that’s what makes the catalog portable across the long tail of SMB tooling.
image_capture_sourceWhere images of items come from. Physical setup matters: lighting, angle, consistency.
- camera installed over a production line
- imaging station integrated with the conveyor system
- handheld scanner used by inspectors
- phone-based capture at pack-out stations
defect_taxonomy_and_examplesWhat 'bad' looks like, specifically. The pattern learns from examples; without enough labeled examples per defect class, it can't be trusted.
- labeled dataset built during the engagement
- ongoing labeling workflow where QC inspectors add to the dataset
- structured defect catalog the operations team maintains
item_record_lookupWhat item is being inspected and what its specifications are. Different items have different inspection criteria.
- ERP item master with QC specifications
- product catalog with inspection criteria
- customer-specific shipment requirements
inspection_decision_destinationWhere pass/fail decisions go. Pass-through for accepted items, divert for rejected items.
- control signal to the production line diverter
- scan log in the warehouse management system
- result feed into the operations dashboard
human_qc_review_stationWhere uncertain or borderline cases get human verification. Critical for the cases the pattern doesn't handle confidently.
- dedicated review station at the QC desk
- tablet at the inspection point with the review UI
- remote review queue for off-line review
audit_image_archiveStored images of inspected items for traceability and quality investigations. Particularly important in regulated industries.
- object store with retention policies
- QC archive in the manufacturing operations system
- compliance archive for regulated products
model_retraining_loopHow human verdicts feed back to improve the pattern. Without this loop, the model can't adapt to new defect types or environmental changes.
- weekly batch of reviewed cases added to the training set
- continuous labeling pipeline where each correction feeds back
- quarterly model retraining process
- 01Capture image of item at the inspection point, tagged with item identifier
image_capture_source - 02Look up the item's specification to know what we're inspecting against
item_record_lookup - 03Run image through the inspection model trained on the defect taxonomy
defect_taxonomy_and_examples - 04Classify result: pass / fail-with-class / uncertainDECISION Threshold-based; uncertain cases route to human review.
- 05For pass: signal accept and archive image
inspection_decision_destinationaudit_image_archive - 06For fail: signal reject with defect class, archive image with classification
inspection_decision_destinationaudit_image_archive - 07For uncertain: route to human review station, hold item if line speed allows
human_qc_review_station - 08Capture human verdicts and feed back into model retraining loop

Structured outputs this pattern produces. Other patterns and client systems can subscribe to them, which is how the catalog composes over time.
defect_rate_signalPer-defect-class and per-SKU defect rates over time. Single most valuable operational signal.
- production quality dashboards
- supplier performance reviews
- manufacturing engineering
false_positive_signalItems the pattern flagged that humans overturned. Critical for tuning the false-positive rate against throughput cost.
- pattern tuning workflows
- operations review
drift_detection_signalStatistical shifts in input image characteristics (lighting changes, equipment degradation) that affect inspection.
- maintenance alerting
- calibration scheduling
