PART 1: QUALITY MANAGEMENT FOUNDATIONS
(Questions 1-60)
Question 1
Who is considered the father of modern quality management, known for his 14 Points
and the Plan-Do-Check-Act (PDCA) cycle?
A) Philip Crosby
B) Joseph Juran
,C) W. Edwards Deming
D) Armand Feigenbaum
Rationale: W. Edwards Deming is considered the father of modern quality management.
His 14 Points and the Plan-Do-Check-Act (PDCA) cycle form the basis of Total Quality
Management (TQM). His work transformed manufacturing and management practices
worldwide after World War II, particularly in Japan .
Question 2
Which quality guru famously stated that "quality is free" and advocated for "zero
defects"?
A) Philip Crosby
B) W. Edwards Deming
C) Joseph Juran
D) Kaoru Ishikawa
Rationale: Philip Crosby famously stated "Quality is free" and advocated for "zero defects."
He argued that the cost of preventing defects is less than the cost of fixing them later.
Crosby emphasized that quality is not just about meeting specifications, but about doing
things right the first time .
Question 3
What does the acronym PDCA stand for?
A) Plan, Do, Check, Act
B) Prepare, Develop, Create, Analyze
C) Process, Design, Control, Assess
D) Predict, Determine, Correct, Adapt
Rationale: PDCA (Plan-Do-Check-Act) is a foundational continuous improvement cycle
used to test changes on a small scale, evaluate results, and implement successful changes
,more broadly. It was popularized by W. Edwards Deming and is also known as the Deming
Cycle or Shewhart Cycle .
Question 4
Which type of variation is inherent to a process and requires management action to
reduce?
A) Special cause variation
B) Common cause variation
C) Assignable variation
D) Out-of-control variation
Rationale: Common cause variation is natural, inherent fluctuation within a stable process.
Reducing this type of variation requires improvements to the process design or
management, not adjustments. Special cause variation (assignable variation) results from
specific, identifiable causes .
Question 5
What is the formula for the lower control limit (LCL) using two standard deviations?
A) LCL = X̄ + 2 σ
B) LCL = X̄ – 2 σ
C) LCL = X̄ / 2 σ
D) LCL = X̄ × 2 σ
Rationale: The lower control limit is calculated as the process mean (X̄) minus a multiple
of the standard deviation (σ). Using two standard deviations gives LCL = X̄ – 2 σ .
Question 6
, Which scenario indicates that a process is not in statistical control?
A) All sample points fall within control limits
B) Sample attributes are consistently outside the control limits
C) Data points show random distribution around the mean
D) No non-random patterns are detected in the chart
Rationale: When sample points fall outside the established control limits, this indicates
special cause variation is present, meaning the process is not in statistical control and
requires investigation .
Question 7
Which metric best evaluates organizational effectiveness?
A) Number of employees
B) Cost per unit
C) Achievement of strategic objectives
D) Operational efficiency
Rationale: Organizational effectiveness is best measured by the achievement of strategic
objectives. This aligns with the Balanced Scorecard approach, which evaluates
performance across financial, customer, internal processes, and learning and growth
perspectives .
Question 8
A Key Performance Indicator (KPI) should be:
A) Broad and general
B) Difficult to measure
C) Directly aligned with strategy
D) Only financial
