A quality engineer discovers that outgoing product has been shipped with a known defect without customer notification. The most appropriate first action is to:
Answer: Notify the customer and initiate a containment response
Immediate customer notification and containment are ethical and contractual obligations when defective product has already shipped.
The acceptance quality limit (AQL) in an acceptance sampling plan defines:
Answer: The worst quality level still considered acceptable as a process average
AQL is the maximum percent nonconforming (or defects per hundred units) that is still considered a satisfactory process average for sampling purposes.
Which lean concept focuses on producing only what the next process step needs, only when needed?
Answer: Just-in-Time (JIT) production
Just-in-Time production eliminates overproduction waste by synchronizing output to downstream demand signals such as kanban cards.
When calibrating a measurement instrument, traceability means the calibration results are:
Answer: Linked to national or international measurement standards through an unbroken chain
Metrological traceability requires an unbroken chain of calibrations connecting the instrument to a recognized national measurement institute such as NIST.
A process producing 3.4 defects per million opportunities (DPMO) operates at approximately which sigma level?
Answer: 6 sigma
Six Sigma is defined as a process capability producing no more than 3.4 DPMO, assuming a 1.5-sigma long-term shift in the mean.
The primary difference between verification and validation in product development is:
Answer: Verification confirms the product was built correctly; validation confirms the right product was built
Verification asks 'Did we build it right?' (compliance to design specifications); validation asks 'Did we build the right thing?' (fitness for intended use).
Which tool is best suited for systematically identifying potential failures in a new product design before production begins?
Answer: Design FMEA
Design FMEA proactively identifies potential failure modes, their effects, and mitigations during the design phase, before tooling or production begins.
