The WGU C215 Operations Management Objective Assessment is a rigorous, competency-based
evaluation designed for students pursuing business degrees at Western Governors University. This
course focuses on the strategic importance of operations management to overall organizational
performance, emphasizing principles of supply-chain management from manufacturing goods to
retail services. The assessment is critical because it validates a candidate's ability to apply planning,
control, and decision-making tools and techniques to real-world operational challenges. The exam
format consists of scenario-based multiple-choice questions covering six core competencies: quality
management methods, capacity planning and location analysis, work system design and scheduling,
operating efficiency, supply chain management, and management and planning. This question bank
has been meticulously crafted to simulate the advanced, application-level difficulty of the actual
assessment. By working through these 200 scenario-driven questions, you will develop the critical
reasoning and technical precision needed to pass on your first attempt.
CORE DOMAINS TESTED
1. Quality Management Methods – Total Quality Management (TQM), Six Sigma, continuous
improvement (PDCA/DMAIC), quality tools (Pareto charts, cause-and-effect diagrams, control
charts, histograms, scatter diagrams), ISO 9000, and Baldrige criteria.
2. Capacity Planning, Location Analysis – Capacity strategies, bottleneck identification, process
design and analysis, facility layout (product, process, fixed-position, cellular), location
analysis techniques (factor rating, center of gravity), and economies of scale.
3. Work System Design and Scheduling – Process and method analysis, work measurement
(time studies, work sampling), job design, scheduling techniques (Gantt charts, sequencing
rules, priority rules), and project management (PERT, CPM, critical path, crashing).
4. Operating Efficiency – Just-in-Time (JIT) systems, Kanban, lean manufacturing, waste
elimination (muda), value stream mapping, and continuous flow.
5. Supply Chain Management – Supply chain strategy, supplier selection and evaluation,
vertical integration, outsourcing, logistics, cross-docking, bullwhip effect, and supply chain
risk management.
6. Management and Planning – Forecasting methods (qualitative and quantitative), aggregate
planning, master production schedule (MPS), inventory management (EOQ, safety stock, ABC
analysis), and material requirements planning (MRP).

QUESTIONS 1-200
Q1: A manufacturing firm has identified that its production process
produces 5% defective units, resulting in significant rework costs. The
operations manager wants to implement a systematic methodology
that focuses on reducing process variation and eliminating defects.
Which quality management approach is most appropriate?
A) Total Quality Management (TQM)
B) Six Sigma
C) ISO 9000 certification
D) Kaizen events only
Rationale: The correct answer is B because Six Sigma is a data-driven
methodology specifically designed to reduce process variation and
eliminate defects to achieve near-perfection (3.4 defects per million
opportunities). Option A is incorrect because TQM is a broader
philosophy that encompasses many quality tools but does not provide
the specific statistical methodology for defect reduction. Option C is
incorrect because ISO 9000 provides a framework for quality
management systems but does not prescribe specific defect-reduction
techniques. Option D is incorrect because Kaizen events are focused
improvement activities but are not as comprehensive as Six Sigma for
systematic defect elimination.
Q2: A hospital is evaluating locations for a new outpatient clinic. The
decision factors include proximity to patients, availability of skilled
staff, cost of facility, and accessibility. The management team assigns
weights to each factor and scores three potential locations. Which
location analysis technique is being used?
,3
A) Center of gravity method
B) Factor rating method
C) Break-even analysis
D) Transportation model
Rationale: The correct answer is B because the factor rating method
allows decision-makers to assign weights to multiple qualitative and
quantitative factors, score each alternative, and calculate weighted
scores to compare locations. Option A is incorrect because the center
of gravity method focuses primarily on minimizing transportation
costs based on distance and volume. Option C is incorrect because
break-even analysis compares fixed and variable costs to determine
profitability at different volumes. Option D is incorrect because the
transportation model is used to minimize shipping costs from multiple
sources to multiple destinations.
Q3: A production supervisor notices that work-in-process inventory is
accumulating in front of one workstation while downstream
workstations are idle. Which term best describes this workstation?
A) Starved station
B) Bottleneck station
C) Blocked station
D) Non-critical station
Rationale: The correct answer is B because a bottleneck is the
workstation with the lowest capacity, causing work to accumulate in
front of it while downstream stations wait for output. Option A is
incorrect because a starved station is one that has no work to process
because it is waiting for input. Option C is incorrect because a blocked
station cannot pass its completed work to the next station. Option D
is incorrect because a non-critical station has excess capacity relative
to demand.

Q4: A company is implementing a lean production system and wants
to eliminate all forms of waste. Which of the following is considered
waste in lean terminology?
A) Value-added processing time
B) Excess inventory
C) Customer-required product features
D) Necessary transportation between workstations
Rationale: The correct answer is B because excess inventory is one of
the seven wastes in lean manufacturing (muda), as it ties up capital
and hides process problems. Option A is incorrect because value-
added processing time is the only activity customers are willing to pay
for. Option C is incorrect because customer-required features
represent value. Option D is incorrect because necessary
transportation is minimized but may be required; however, excess or
unnecessary transportation is waste.
Q5: A retailer uses a forecasting method that averages the sales of
the most recent three months to predict next month's demand.
Which forecasting technique is being used?
A) Exponential smoothing
B) Simple moving average
C) Weighted moving average
D) Linear regression
Rationale: The correct answer is B because a simple moving average
uses the arithmetic mean of the most recent n periods. Option A is
incorrect because exponential smoothing assigns exponentially
decreasing weights to older observations. Option C is incorrect
because a weighted moving average assigns different weights to each
period. Option D is incorrect because linear regression establishes a
mathematical relationship between demand and other variables.
