1. 1. You inspect a lot to a normal single sampling plan. The accept number is 10 and you find 11 major defects. The merchandiser asks you to pass it because the vessel closes tonight. What is the correct action?

   Pass it and note the exceptionReject the lot against the plan, then let commercial decide on sorting, partial shipment or a buyer concessionRe-inspect a second sample and average the resultsReclassify two defects as minor

2. 2. A broken needle fragment is found inside one collar during final inspection. What follows?

   Record it as a major defect and continueTreat it as critical: stop the lot, run the broken-needle procedure and metal detection before any shipment decisionRemove the piece and pass the lotRaise it at the weekly quality meeting

3. 3. Chest width reads 2 cm over tolerance on three pieces in a size set. What do you check before blaming sewing?

   The buyer's size chart onlyHow the piece was measured — fold, tension, tape and measuring point — then the pattern and cutting before sewingNothing; the operator is responsibleThe finishing press only

4. 4. What does a measurement audit tell you that a single size set does not?

   Whether the specification is commercially correctWhether the process holds the tolerance across sizes, colours and time, rather than in one sampleWhether the fabric shrinksWhether the buyer will accept the style

5. 5. Two inspectors measure the same 10 garments and their results differ by up to 1.5 cm on the same point. What is the first problem to fix?

   The sewing processMeasurement agreement between inspectors: the same method, the same landmarks, the same tape tensionThe tolerance, which is too tightThe fabric supplier

6. 6. Why is in-line inspection cheaper than end-line inspection for the same defect?

   It uses fewer inspectorsIt catches the fault before more operations, pressing and packing add cost to a piece that must be reworked or scrappedIt uses a smaller sampleIt avoids the buyer's audit

7. 7. Your defect Pareto shows 'stitching' as 62 per cent of findings. What is the weakness of that chart?

   Pareto charts do not suit quality data'Stitching' is too broad to act on: skipped stitch, tension, seam pucker and open seam have different causes and fixesThe percentage is too high to be realIt needs to be shown monthly

8. 8. An AQL plan reduces the sample when past lots have been good. What is the risk you must state when you apply it?

   There is no risk; it is the buyer's own ruleA smaller sample detects a rise in defect rate later, so the switching rules and the trigger to return to normal inspection must be followed strictlyThe lot has to be re-inspected anywayIt doubles the inspection time
