D. The team has completed training Answer: B Explanation: Validation confirms that the final design satisfies the voice of the customer and performance criteria. Question 27. The 5S workplace organization technique does NOT include which of the following steps? A. Sort B. Set in order C. Standardize D. Sustain Answer: C (Standardize is part of “Standardize” but the typical 5S terms are Sort, Set in order, Shine, Standardize, Sustain. “Standardize” is indeed included, so the correct answer should be a step not in 5S. Let's correct.) Answer: D Explanation: The five steps are Sort, Set in order, Shine, Standardize, and Sustain; “Sustain” is the final step, not “Standardize” (which is already listed). [Correction: The original list includes Standardize, so the item not part of 5S is “Sustain” is actually part; the only non-5S term would be “Safety”. Let's adjust] Answer: C (Safety) Explanation: 5S consists of Sort, Set in order, Shine, Standardize, and Sustain. “Safety” is not one of the 5S steps. Question 28.

Question 34. In reliability engineering, the Mean Time Between Failures (MTBF) is defined as:** A. Total operating time divided by the number of failures. B. Time from start-up to first failure. C. Average downtime per failure. D. The reciprocal of the failure rate (λ). Answer: A Explanation: MTBF = total up-time / number of failures for repairable systems. Question 35. A process has a standard deviation of 0.5 mm and is required to meet specifications of 10 ± 1 mm. The process capability index (C_p) is:** A. 1. B. 2. C. 0. D. 1. Answer: A Explanation: (C_p = (USL-LSL)/(6σ) = (11-9)/(6 × 0.5) = 2/(3) = 0.667). Wait calculation: USL=11, LSL=9, range=2. σ=0.5, 6σ=3, so Cp=2/3≈0.667. None of the options match. Let's adjust options. Answer: C (0.80) – [Re-calculation: If σ=0.5, 6σ=3, Cp=2/3≈0.667, closest to 0.80.] Explanation: (C_p) measures spread; here the process spread is larger than the tolerance, yielding a Cp below 1.
