Question 1: A manufacturing firm is evaluating its inventory control system. It has determined that 20%
of its inventory items account for 80% of its total annual consumption value. Which inventory
classification system is the company applying?
A. FSN Analysis
B. VED Analysis
C. XYZ Analysis
D. ABC Classification
CORRECT ANSWER: D. ABC Classification
Rationale: ABC classification is a method for determining the level of control and frequency of review
of inventory items based on their value and importance. Class A items (typically 10-20% of items)
account for 70-80% of the annual consumption value, making them the highest priority.
Question 2: A company’s marketing plan indicates a need to support a new product line. In developing
the aggregate plan, which key components are budgeted to align with the marketing strategy?
A. Unit cost, selling price, and profit margin
B. Fixed assets, variable costs, and overhead
C. Direct materials, direct labor, and manufacturing overhead
D. Finished products, inventory, backlogs, workforce size, and aggregate production rate
CORRECT ANSWER: D. Finished products, inventory, backlogs, workforce size, and aggregate production
rate
Rationale: An aggregate plan includes the budgeted levels of finished products, inventory, backlogs,
workforce size, and aggregate production rate needed to support the marketing plan. It translates the
marketing plan into a production plan that balances capacity and demand.
,Question 3: A quality team is brainstorming to identify all possible causes of a specific quality problem.
Which of the seven quality management tools should they use?
A. Control Chart
B. Cause-and-Effect Diagram
C. Scatter Diagram
D. Checklist
CORRECT ANSWER: B. Cause-and-Effect Diagram
Rationale: A cause-and-effect diagram (also known as a fishbone or Ishikawa diagram) is a problem-
solving tool used to identify all potential causes of a quality problem. It helps teams systematically
explore various categories of causes and their sub-causes during brainstorming sessions.
Question 4: A quality manager needs a simple tool to record the frequency of specific defects observed
during an inspection. Which of the seven quality management tools is most suitable for this task?
A. Pareto Chart
B. Histogram
C. Checklist
D. Scatter Diagram
CORRECT ANSWER: C. Checklist
Rationale: A checklist is a simple yet effective fact-finding tool that lists common defects and allows
the worker to record the number of observed occurrences. This data collection helps focus on the most
frequent defects.
Question 5: An operations manager wants to evaluate whether a process is operating within its specified
expectations regarding a measured value, such as weight. Which of the seven quality management tools
should be used?
A. Flowchart
B. Pareto Analysis
C. Control Chart
D. Histogram
CORRECT ANSWER: C. Control Chart
,Rationale: Control charts are used to evaluate whether a process is operating within set expectations
relative to a measured value (e.g., weight, width, volume). They help distinguish between common
cause and assignable cause variation by plotting data over time against control limits.
Question 6: A team is investigating a potential relationship between the speed of a production line and
the number of defects produced. Which quality tool would best help them visualize this correlation?
A. Control Chart
B. Histogram
C. Pareto Chart
D. Scatter Diagram
CORRECT ANSWER: D. Scatter Diagram
Rationale: A scatter diagram is a graph that shows how two variables are related to each other. It is
particularly useful for detecting the amount of correlation, or the degree of linear relationship,
between two variables, such as production speed and defect count.
Question 7: A manager has compiled a list of customer complaints and wants to prioritize the most
significant issues. Which quality management tool should be used to focus efforts on the "vital few"
problems?
A. Cause-and-Effect Diagram
B. Control Chart
C. Pareto Analysis
D. Scatter Diagram
CORRECT ANSWER: C. Pareto Analysis
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). The logic is that only a few quality problems
(the "vital few") are critical, while many others (the "trivial many") are not, allowing management to
focus efforts where they will have the greatest impact.
Question 8: A quality analyst needs to understand the distribution of observed values for a process
variable. Which tool provides a visual representation of the frequency distribution?
A. Checklist
B. Control Chart
C. Scatter Diagram
, D. Histogram
CORRECT ANSWER: D. Histogram
Rationale: A histogram is a chart that shows the frequency distribution of observed values of a
variable. It helps visualize the central tendency, dispersion, and shape of the data distribution, making
it easier to understand process capability and identify potential issues.
Question 9: According to the Total Quality Management (TQM) philosophy, which component is the
fundamental principle that quality should be built into the process rather than inspected in at the end?
A. Customer Focus
B. Continuous Improvement
C. Employee Empowerment
D. Process Management
CORRECT ANSWER: D. Process Management
Rationale: Process management is a core component of TQM, emphasizing that quality should be built
into the process itself. This proactive approach focuses on designing and controlling processes to
prevent defects, rather than relying solely on end-of-line inspection to catch them after they occur.
Question 10: Which of the following is NOT one of the seven core components of the Total Quality
Management (TQM) Philosophy?
A. Customer Focus
B. Continuous Improvement
C. Managing Supplier Quality
D. Maximizing Shareholder Value
CORRECT ANSWER: D. Maximizing Shareholder Value
Rationale: The seven core components of TQM are: customer focus, continuous improvement,
employee empowerment, use of quality tools, product design, process management, and managing
supplier quality. Maximizing shareholder value is a financial objective, not a core operational
component of the TQM philosophy.
Question 11: Which definition of quality focuses on how well a product performs its intended function
or use?
A. Conformance to Specifications
