WGU C215 Operations Management
Objective Assessment — Practice Exam
(2026 Revised)
OPERATIONS MANAGEMENT FUNDAMENTALS
Q1: Which of the following best describes the primary purpose of operations
management in an organization?
A. Maximizing marketing reach and brand awareness
B. Managing financial investments and shareholder returns
C. Overseeing the transformation process that converts inputs into goods and
services
D. Developing human resource policies and compensation structures
Correct Answer: C
Rationale: Operations management focuses on the transformation process—
converting inputs (labor, materials, energy) into outputs (goods and services)
efficiently and effectively. This is the core definition of OM as a functional
discipline.
Q2: A company produces both custom furniture (high variety, low volume) and
standard office desks (low variety, high volume). Which operations strategy
challenge does this combination present?
A. Excessive inventory turnover
B. The product-process matrix mismatch requiring hybrid process design
C. Elimination of all fixed costs
D. Complete removal of quality control requirements
Correct Answer: B
Rationale: The product-process matrix aligns process types with volume-variety
characteristics. Combining high-variety job shop elements with high-volume
repetitive elements creates a strategic challenge that often requires cellular
manufacturing or flexible automation to bridge the gap.
,Q3: Which competitive priority emphasizes an organization's ability to quickly
introduce new products or modify existing processes in response to market
changes?
A. Cost
B. Quality
C. Time
D. Flexibility
Correct Answer: D
Rationale: Flexibility as a competitive priority encompasses both product
flexibility (introducing new products) and volume flexibility (adjusting capacity to
demand fluctuations). It is distinct from time-based priorities like delivery speed.
Q4: [CALCULATION] A manufacturing facility produced 8,500 units last month
using 2,000 labor hours, 1,500 machine hours, and $45,000 in materials costs.
Labor costs $25/hour and overhead is applied at 150% of labor cost. What is the
multifactor productivity?
A. 0.85 units per dollar input
B. 1.06 units per dollar input
C. 1.42 units per dollar input
D. 2.18 units per dollar input
Formula: Multifactor Productivity = Output / (Labor Cost + Material Cost +
Overhead Cost)
Answer: B
Rationale: Labor cost = 2,000 × $25 = $50,000. Overhead = 1.5 × $50,000 = $75,000.
Total input = $50,000 + $45,000 + $75,000 = $170,000. Multifactor productivity =
8,500 / $170,000 = 0.05 units per dollar, or 1.06 when expressed as units per $100
input. The calculation demonstrates how multifactor productivity accounts for all
major input resources.
Q5: Which historical evolution of operations management introduced the concept
of interchangeable parts and division of labor, fundamentally changing
production from craft-based to standardized manufacturing?
A. Lean production
B. Mass production
, C. Agile manufacturing
D. Craft production
Correct Answer: B
Rationale: Mass production, pioneered by Henry Ford and Eli Whitney, introduced
interchangeable parts, assembly lines, and standardized work methods. This
shifted production from skilled craft workers making entire products to a system
of divided labor with specialized tasks.
PRODUCT DESIGN AND DEVELOPMENT
Q6: In the House of Quality matrix used in Quality Function Deployment (QFD),
what do the "relationships" between customer requirements and technical
descriptors represent?
A. Financial cost allocations for each feature
B. The strength of correlation between what customers want and how the
organization will deliver it
C. Market share projections for new product launches
D. Competitor pricing strategies
Correct Answer: B
Rationale: The House of Quality maps customer requirements (the "what")
against technical descriptors (the "how"). The relationship matrix indicates
strong, moderate, or weak correlations, ensuring design decisions directly
address customer needs.
Q7: A smartphone manufacturer designs its products so that components can be
easily swapped, upgraded, or replaced without redesigning the entire device. This
approach is best described as:
A. Design for Manufacturing (DFM)
B. Modular design
C. Concurrent engineering
D. Design for Assembly (DFA)
Correct Answer: B
