WGU C215 Operations Management 2026 OA &
PA Review — 300 Questions with Answers &
Rationales
Welcome to this comprehensive exam review for WGU C215: Operations Management.
This resource is designed to mirror the actual 2026 Objective Assessment (OA) and
Performance Assessment (PA) content. Each question includes a detailed rationale to
deepen your understanding and ensure you are fully prepared for success on your first
attempt.
PART 1: TOTAL QUALITY MANAGEMENT (TQM) & QUALITY TOOLS
Questions 1–80
1. Which total quality management (TQM) process was developed to stress management's
responsibility for quality?
A) ISO 9000
B) Six Sigma
C) 14 points for quality improvement
D) PDSA cycle
Correct Answer: C
Rationale: W. Edwards Deming developed the "14 Points" to guide companies in quality
improvement, emphasizing management's responsibility for quality. This was a shift from
the traditional view that workers were solely responsible for defects.
2. Which TQM process consists of 13 published standards and guidelines?
A) Six Sigma
B) ISO 14000
C) ISO 9000
D) Malcolm Baldrige Award
Correct Answer: C
Rationale: ISO 9000 is a set of international quality standards and a certification
demonstrating companies have met all the standards specified. ISO 14000 addresses
environmental responsibility, not quality management.
,3. What is the most important principle of TQM?
A) Maximizing shareholder value
B) Meeting the needs and satisfaction of customers
C) Enhancing employee morale
D) Reducing operational costs
Correct Answer: B
Rationale: TQM is fundamentally a customer-focused philosophy. Quality is defined as
meeting or exceeding customer expectations. Without customer satisfaction, continuous
improvement efforts lack direction and purpose.
4. The common theme in TQM across all functions in an organization is to:
A) Maximize shareholder value
B) Eliminate all forms of waste
C) Satisfy customer needs
D) Reduce employee turnover
Correct Answer: C
Rationale: TQM's most important principle is its focus on customer needs and
satisfaction. All quality efforts must ultimately align with what customers value.
5. What is the primary focus of Six Sigma in operations management?
A) Enhancing employee satisfaction
B) Reducing defects and improving quality
C) Lowering operational costs
D) Increasing production speed
Correct Answer: B
Rationale: Six Sigma is a disciplined, data-driven methodology for eliminating defects,
driving toward six standard deviations between the mean and the nearest specification
limit, resulting in approximately 3.4 defective parts per million.
6. What quality tool is used to record the frequency of occurrence of certain process
failures?
A) Pareto chart
B) Checklist
C) Cause-and-effect diagram
D) Control chart
Correct Answer: B
,Rationale: A checklist is a list of common defects and the number of observed
occurrences of these defects. It is a simple yet effective fact-finding tool that allows the
worker to collect specific information regarding observed defects.
7. Which quality tool is also known as a fishbone diagram?
A) Pareto chart
B) Scatter diagram
C) Cause-and-effect diagram
D) Histogram
Correct Answer: C
Rationale: A cause-and-effect diagram identifies potential causes of particular quality
problems and is often called a fishbone diagram because of its shape. It is a problem-
solving tool commonly used by quality control teams.
8. What type of chart evaluates whether a process is operating within expectations?
A) Histogram
B) Control chart
C) Scatter diagram
D) Pareto chart
Correct Answer: B
Rationale: Control charts evaluate whether a process is operating within set expectations
relative to some measured value, such as weight, width, or volume.
9. Graphs that show how two variables relate to each other are called:
A) Control charts
B) Flowcharts
C) Scatter diagrams
D) Histograms
Correct Answer: C
Rationale: Scatter diagrams plot pairs of numerical data points to reveal relationships or
correlations between variables—positive, negative, or none. They help determine if
changes in one variable cause changes in another.
10. What TQM tool uses the logic that only a few quality problems are important, whereas
many others are not critical?
A) Histogram
B) Pareto analysis
, C) Service blueprint
D) Flowchart
Correct Answer: B
Rationale: Pareto analysis is a technique used to identify quality problems based on their
degree of importance, based on the Pareto principle (80/20 rule) that a minority of causes
leads to the majority of problems.
11. A chart that shows the frequency distribution of observed values of a variable is called
a:
A) Pareto chart
B) Control chart
C) Scatter diagram
D) Histogram
Correct Answer: D
Rationale: A histogram displays data distribution by grouping values into intervals (bins)
and showing frequency as bar heights. It reveals the shape, center, and spread of data,
helping identify patterns such as normal distribution or skewness.
12. A schematic of the sequence of steps involved in an operation or process is called a:
A) Checklist
B) Flowchart
C) Pareto chart
D) Control chart
Correct Answer: B
Rationale: A flowchart is a schematic of the sequence of steps involved in an operation or
process. It provides a visual tool that is easy to use and understand. By seeing the steps
involved, everyone develops a clear picture of how the operation works and where
problems could arise.
13. Fitness for use as a definition of quality means:
A) The product meets manufacturing specifications
B) How well the product performs for its intended use
C) The product has the lowest possible price
D) The product has the most features
Correct Answer: B
