Which statement about sampling plans is true?

Which statement about sampling plans is true?

• A. The sampling plan is never used.
• B. A sampling plan is written specifically for that part when permitted.
• C. The sampling plan is always company-wide.
• D. The sampling plan is optional.

Answer: (B)

Sampling plans are not a one-size-fits-all tool. When a contract or specification allows it, a plan is created specifically for that part, laying out how many units to inspect, the sampling method, and the acceptance criteria for that part. This part-specific plan matches the risk and criticality of the part and ensures the inspection effort is appropriate, not excessive, while still meeting customer requirements. That’s why writing a sampling plan specifically for that part when permitted is the best description. The other statements don’t fit typical QA practice: sampling plans aren’t always unused, they’re not automatically company-wide, and they’re not inherently optional when the contract calls for them.
