Section 1: Quality Management Foundations (Questions
1–15)
Q1. Who is considered the primary architect of the Plan-Do-Check-Act (PDCA)
cycle and a foundational figure in modern quality management?
A. Joseph Juran
B. Philip Crosby
C. W. Edwards Deming
D. Armand Feigenbaum
Correct Answer: C
Rationale: W. Edwards Deming is credited with introducing the PDCA (often called the
Deming or Shewhart Cycle) and the 14 Points for management, which form the basis
of Total Quality Management (TQM). Juran focused on the quality trilogy, Crosby on
"zero defects," and Feigenbaum on total quality control.
Q2. Which quality philosophy emphasizes achieving long-term success through
customer satisfaction by integrating all organizational functions to focus on
continuous improvement?
A. Six Sigma
B. Total Quality Management (TQM)
C. Just-In-Time (JIT)
D. Kaizen Blitz
Correct Answer: B
Rationale: TQM is a comprehensive, organization-wide approach that commits to
continuous improvement and focuses on meeting customer needs by involving all
employees.
,Q3. A manager at a manufacturing plant wants to identify the potential causes
of a recurring defect. Which tool is specifically designed to visually organize
these potential causes into categories like Materials, Methods, and Machinery?
A. Pareto Chart
B. Control Chart
C. Fishbone (Ishikawa) Diagram
D. Flowchart
Correct Answer: C
Rationale: The Fishbone diagram, also known as the Ishikawa diagram, is a cause-and-
effect tool used to brainstorm and categorize potential root causes of a problem.
Q4. In Garvin's dimensions of quality, what does "reliability" specifically
measure?
A. A product's appearance and feel.
B. The probability of a product malfunctioning or failing within a given time period.
C. How quickly a product can be repaired.
D. The degree to which a product meets its design specifications.
Correct Answer: B
Rationale: Reliability refers to the consistency of performance over time and the
likelihood of failure. "Conformance" (D) measures adherence to specs, while
"serviceability" (C) measures repair speed.
Q5. Which standard provides the requirements for a Quality Management
System (QMS) and is used by organizations to demonstrate their ability to
consistently provide products and services that meet customer and regulatory
requirements?
A. ISO 14001
B. ISO 9001
C. ISO 45001
D. ISO 31000
Correct Answer: B
Rationale: ISO 9001 is the international standard specifically for Quality Management
Systems. It sets out the criteria for a QMS and is the only standard in the ISO 9000
family that can be certified.
Q6. A call center is tracking the average time it takes to answer a call. They plot
this data daily on a chart with an upper control limit (UCL) and a lower control
limit (LCL). What is the primary purpose of this chart?
A. To set annual employee bonuses.
B. To determine the root cause of long wait times.
C. To monitor process stability and distinguish between common and special cause
, variation.
D. To compare their performance to a competitor.
Correct Answer: C
Rationale: A control chart is used for statistical process control (SPC). Its main function
is to monitor process behavior over time, identifying when a process is "in control"
(only common cause variation) or "out of control" (presence of special cause variation).
Q7. What does the acronym "VOC" stand for in a quality management context?
A. Variance of Control
B. Verification of Compliance
C. Voice of the Customer
D. Value of Capacity
Correct Answer: C
Rationale: Voice of the Customer (VOC) is a process used to capture the stated and
unstated needs, wants, and expectations of the customer. This information is used to
guide product and service design.
Q8. A firm has passed an audit conducted by an external, independent registrar.
They are now listed in the organization's directory. What has this firm
achieved?
A. A Baldrige Award
B. A Shingo Prize
C. ISO Certification
D. A Six Sigma Black Belt
Correct Answer: C
Rationale: ISO certification (e.g., ISO 9001) is granted after an independent external
audit verifies that the organization's QMS meets the standard's requirements.
Q9. Which cost category includes expenses incurred from defects
discovered after the product has been shipped to the customer, such as
warranty claims and product recalls?
A. Prevention Costs
B. Appraisal Costs
C. External Failure Costs
D. Internal Failure Costs
Correct Answer: C
Rationale: External failure costs are the most damaging quality costs, occurring when a
defect is found by the customer. Internal failure costs (scrap, rework) are found before
shipment.
