Question 1: Which of the following best defines quality from a customer-centric
perspective in quality management?
A. Conformance to engineering specifications
B. Absence of defects in the final product
C. Fitness for use and meeting customer expectations
D. Compliance with ISO 9001 certification requirements
CORRECT ANSWER: C. Fitness for use and meeting customer expectations
Rationale: Quality from a customer-centric perspective emphasizes that a product or
service must fulfill the needs, expectations, and intended use of the customer. While
conformance to specifications and defect reduction are important, the ultimate
measure of quality is whether the customer perceives value and satisfaction, as
articulated by quality guru Joseph Juran's concept of "fitness for use."
Question 2: In the context of Total Quality Management (TQM), which principle
emphasizes that quality improvement is the responsibility of every employee in the
organization?
A. Process-centered approach
B. Customer focus
C. Employee involvement
D. Strategic and systematic approach
CORRECT ANSWER: C. Employee involvement
Rationale: TQM asserts that quality is not solely the domain of a quality department but
requires engagement from all organizational levels. Employee involvement empowers
staff at every level to contribute ideas, identify problems, and participate in continuous
improvement initiatives, fostering a culture of shared accountability for quality
outcomes.
Question 3: Which quality guru is most closely associated with the "14 Points for
Management" that form a foundation for organizational transformation toward
quality?
A. Joseph M. Juran
B. Philip B. Crosby
C. W. Edwards Deming
D. Kaoru Ishikawa
CORRECT ANSWER: C. W. Edwards Deming
,Rationale: W. Edwards Deming introduced the "14 Points for Management" as a
comprehensive framework for transforming business effectiveness through quality.
These points emphasize leadership commitment, elimination of fear, continuous
improvement, and breaking down barriers between departments, forming a cornerstone
of modern quality management philosophy.
Question 4: What is the primary purpose of a Pareto chart in quality management?
A. To monitor process stability over time
B. To identify the vital few causes that contribute to the majority of problems
C. To display the frequency distribution of a dataset
D. To map the sequence of steps in a process
CORRECT ANSWER: B. To identify the vital few causes that contribute to the
majority of problems
Rationale: A Pareto chart applies the 80/20 principle (Pareto principle) to quality data,
visually highlighting the most significant factors contributing to defects or issues. By
focusing improvement efforts on these "vital few" causes, organizations can achieve
maximum impact with limited resources, aligning with efficient problem-solving
methodologies.
Question 5: In Statistical Process Control (SPC), what does a point falling outside
the control limits on an X-bar chart typically indicate?
A. The process is operating within expected random variation
B. The process mean has shifted due to a special cause of variation
C. The sample size was insufficient for accurate measurement
D. The specification limits have been violated
CORRECT ANSWER: B. The process mean has shifted due to a special cause of
variation
Rationale: Control limits on an X-bar chart represent the expected range of variation due
to common causes. A point beyond these limits signals a special (assignable) cause of
variation, indicating that the process is out of statistical control and requires
investigation to identify and eliminate the root cause of the shift.
Question 6: Which of the following is NOT one of the seven basic quality tools?
A. Histogram
B. Scatter diagram
C. Gantt chart
D. Check sheet
CORRECT ANSWER: C. Gantt chart
Rationale: The seven basic quality tools, popularized by Kaoru Ishikawa, are: cause-
and-effect diagram, flowchart, check sheet, Pareto chart, histogram, control chart, and
,scatter diagram. A Gantt chart is a project management tool for scheduling tasks and is
not classified among the foundational quality improvement tools.
Question 7: The PDCA cycle, a cornerstone of continuous improvement, stands for:
A. Plan, Do, Check, Act
B. Prepare, Develop, Control, Assess
C. Process, Design, Create, Analyze
D. Prevent, Detect, Correct, Avoid
CORRECT ANSWER: A. Plan, Do, Check, Act
Rationale: The PDCA (Plan-Do-Check-Act) cycle, also known as the Deming Cycle, is an
iterative four-step management method used for continuous improvement. It involves
planning a change, implementing it on a small scale, checking the results, and acting to
standardize or refine the approach based on findings.
Question 8: In the context of cost of quality, which category includes expenses
related to rework, scrap, and downtime caused by defects discovered before
delivery to the customer?
A. Prevention costs
B. Appraisal costs
C. Internal failure costs
D. External failure costs
CORRECT ANSWER: C. Internal failure costs
Rationale: Internal failure costs arise when defects are identified before the product
reaches the customer. These include costs of rework, scrap, retesting, and downtime.
Investing in prevention and appraisal activities can reduce internal failure costs,
improving overall quality efficiency.
Question 9: Which ISO standard specifically provides guidelines for auditing
management systems, including quality management systems?
A. ISO 9000
B. ISO 9001
C. ISO 19011
D. ISO 14001
CORRECT ANSWER: C. ISO 19011
Rationale: ISO 19011 offers guidance on auditing management systems, covering
principles of auditing, managing audit programs, and conducting audits. While ISO 9001
specifies requirements for a quality management system, ISO 19011 supports the
evaluation of conformity to such standards through effective auditing practices.
Question 10: What is the primary objective of Six Sigma methodology?
, A. To reduce process variation and eliminate defects to achieve near-perfect quality
B. To implement just-in-time inventory systems
C. To increase employee satisfaction through participative management
D. To standardize documentation across global operations
CORRECT ANSWER: A. To reduce process variation and eliminate defects to
achieve near-perfect quality
Rationale: Six Sigma is a data-driven methodology focused on reducing process
variation and defects to a level of 3.4 defects per million opportunities (DPMO). It
employs structured approaches like DMAIC (Define, Measure, Analyze, Improve,
Control) to achieve measurable and sustainable quality improvements.
Question 11: In Quality Function Deployment (QFD), what is the primary purpose of
the "House of Quality"?
A. To calculate process capability indices
B. To translate customer requirements into technical design specifications
C. To schedule quality audits across departments
D. To prioritize suppliers based on delivery performance
CORRECT ANSWER: B. To translate customer requirements into technical design
specifications
Rationale: The House of Quality is a matrix used in QFD to systematically link customer
needs (the "voice of the customer") with engineering characteristics, competitive
assessments, and target values. This ensures that product development efforts are
aligned with what customers truly value.
Question 12: Which control chart is most appropriate for monitoring the number of
defects per unit when the sample size is constant?
A. p-chart
B. np-chart
C. c-chart
D. u-chart
CORRECT ANSWER: C. c-chart
Rationale: The c-chart is used to monitor the count of defects (nonconformities) per
unit when the sample size is fixed. In contrast, the u-chart is used when sample sizes
vary, while p-charts and np-charts monitor the proportion or number of defective units,
not defects per unit.
Question 13: What does the term "Kaizen" refer to in quality management?
A. A statistical technique for hypothesis testing
B. A philosophy of continuous, incremental improvement involving all employees
C. A certification standard for quality auditors
D. A software tool for automated process monitoring
