質問 # 24
The primary focus of design FMEA (DFMEA) is to
- A. predict failure frequencies
- B. mitigate failure modes
- C. minimize measurement variation
- D. identify personnel responsible for implementation
正解：B
解説：
Design Failure Mode and Effects Analysis (DFMEA) is a systematic method for evaluating a design to identify potential failure modes, their causes, and effects, and to prioritize the actions to mitigate these failures.
* Identify Personnel Responsible for Implementation:
* While important for action plans, it is not the primary focus of DFMEA.
* Predict Failure Frequencies:
* DFMEA does consider failure frequencies, but the primary goal is to address and mitigate failures.
* Minimize Measurement Variation:
* This is more relevant to process control and not the primary focus of DFMEA.
* Mitigate Failure Modes:
* The main objective of DFMEA is to identify potential failure modes and implement actions to reduce or eliminate the risks associated with these failures.
* This involves analyzing the design to foresee where it might fail and taking preventive measures
* to improve reliability and safety.
References: Quality engineering and risk management texts, specifically those discussing the principles and objectives of DFMEA.
質問 # 25
Which of the following would be considered the WEAKEST reason to initiate an audit?
- A. Identify the root cause of a recent problem.
- B. Verify that a quality system continues to meet requirements.
- C. To compare actual practice to a defined standard.

質問 # 26
Which of the following assumptions is a robustness factor suitable for validating statistical conclusions?
- A. Violated expectations of test
- B. Low reliability of treatment
- C. High statistical power
- D. Low reliability of measures
正解：C
解説：
Robustness in statistical conclusions often refers to the ability to draw valid conclusions even when certain assumptions are violated. One of the critical factors for robustness is high statistical power, which refers to the probability of correctly rejecting the null hypothesis when it is false.Reason: High statistical power increases the likelihood that the test will detect a true effect if it exists, thereby supporting the validity of the conclusions.

質問 # 29
When subgroups are selected in a way that minimizes the opportunity for variation within a subgroup and maximizes the opportunity to detect variation between subgroups, this subgrouping is known as
- A. rational
- B. random
- C. controlled
- D. assignable
正解：A
解説：
When subgroups are selected in a way that minimizes the opportunity for variation within a subgroup and maximizes the opportunity to detect variation between subgroups, this subgrouping is known as rational subgrouping. Rational subgrouping is a concept used in control charting to ensure that the data within each subgroup is homogeneous, making it easier to detect special causes of variation between subgroups.References:

* ASQ Certified Quality Engineer Handbook.
質問 # 30
A company's quality policy should be developed by the
- A. quality engineering department
- B. manager of quality
- C. most productive process improvement team
- D. executive level of management
正解：D
解説：
The quality policy sets the overall intentions and direction of an organization regarding quality, as formally expressed by top management.
It should be developed by the executive level of management to ensure alignment with the company's strategic goals and to demonstrate commitment to quality.
Involvement of top management ensures that the policy is authoritative and can drive the entire organization towards quality objectives.
References: ISO 9001:2015 and the ASQ "Quality Management Systems Handbook" emphasize the role of top management in developing the quality policy.
質問 # 31
Which of the following statements is true about the average outgoing quality limit (AOQL)?
- A. It can be used instead of ANSI ASQ Z1.4 single sampling plans.
- B. It cannot be used to define the Dodge-Romig defect acceptance number.
- C. It is the replacement measure for the acceptance quality limit (AQL).
- D. It assumes screening and replacement of nonconforming units.
正解：D
解説：
The Average Outgoing Quality Limit (AOQL) is a key concept in quality control and inspection plans. It is defined as the maximum average outgoing quality over all possible levels of incoming quality for a given acceptance sampling plan. The AOQL is particularly used in situations where 100% inspection or screening of rejected lots is performed, meaning nonconforming units are identified and replaced. This ensures that the outgoing quality is controlled even if the incoming quality fluctuates.

質問 # 32
Which of the following techniques is used when implementing single minute exchange of die?
- A. Separating internal and external setup operations
- B. Eliminating the use of intermediate jigs
- C. Adjusting and eliminating mechanization
- D. Using more fasteners and clamps
正解：A
解説：
When implementing Single Minute Exchange of Die (SMED), separating internal and external setup operations is a key technique. Internal setup operations are those that can only be performed when the machine is stopped, whereas external setup operations can be performed while the machine is running. By distinguishing and optimizing these operations, setup times can be significantly reduced.References:
* Single Minute Exchange of Die: A Comprehensive Guide to SMED by Shigeo Shingo.
* Lean Production Simplified by Pascal Dennis.

2. Design change
3. Training
- A. 2,1,3
- B. 1,3,2
- C. 1,2,3
- D. 2,3,1
