Read the first 7 Quality Assurance in Purchasing flashcards as text

  1. A supplier consistently delivers products with a defect rate of 0.5%. According to Six Sigma principles, what sigma level does this approximate?

    Answer: Four sigma

    A defect rate of approximately 0.5% (5,000 DPMO) corresponds to roughly four sigma performance.

  2. Which quality tool is BEST suited for identifying the root cause of a recurring supplier defect?

    Answer: Fishbone (Ishikawa) diagram

    The Ishikawa (fishbone) diagram systematically categorizes potential causes (machines, methods, materials, manpower) to identify root causes.

  3. An incoming inspection reveals that 3 out of 150 sampled units are defective. What is the approximate defect rate?

    Answer: 2%

    3 defective units out of 150 sampled equals 3/150 = 0.02, or 2%.

  4. A purchasing manager wants to verify a supplier's quality management system without conducting a full audit. Which approach is MOST appropriate?

    Answer: Reviewing the supplier's ISO 9001 certification

    ISO 9001 certification from an accredited registrar independently confirms that a supplier's QMS meets international standards.

  5. Which contract clause gives a buyer the right to inspect goods at the supplier's facility before shipment?

    Answer: Source inspection clause

    A source inspection clause contractually grants the buyer access to inspect and approve goods at the supplier's location prior to delivery.

  6. What does 'zero defects' as a quality philosophy primarily emphasize?

    Answer: Prevention of defects rather than detection and correction

    Philip Crosby's zero defects philosophy stresses that doing things right the first time through prevention is more cost-effective than finding and fixing errors.

  7. A buyer receives a shipment that does not meet purchase order specifications. What is the FIRST step in formal quality nonconformance management?

    Answer: Document and quarantine the nonconforming material

    Nonconforming material must first be identified, documented, and segregated to prevent its inadvertent use before corrective action is initiated.
