Consider the following statements about defect management.
1. Fractography identifies the flaw that initiated a fracture.
2. Process control detects drift before defects appear.
3. Final inspection alone is sufficient for quality assurance.

  • A.1 and 2 only
  • B.3 only
  • C.1 only
  • D.All of them

Answer: A

Correct answer: 1 and 2 only

Statements 1 and 2 are correct: fractography identifies the initiating flaw, and process control catches drift before it produces defects at all. Statement 3 is the belief the other two exist to displace - final inspection finds defects after every cost of making them has been incurred, and it cannot find those it does not test for.
