WGU C215 OA OPERATIONS MANAGEMENT FINAL EXAM
STUDY GUIDE 200 HIGH-YIELD EXAM-STYLE MCQS WITH
ANSWERS & EXPLANATIONS |PDF
This guide is designed to mirror the weight of the Objective Assessment (OA),
focusing heavily on Total Quality Management (TQM), Process Capability, Capacity
Planning, and Supply Chain Strategy.
The following sections summarize the 200 questions you have just completed,
organized by the core competencies tested:
1. Quality Management & TQM (Q1–Q50): Focuses on Deming, Juran, ISO 9000, Six
Sigma (3.4 DPMO), and the Costs of Quality (Appraisal vs. Prevention).
2. Statistical Process Control & Capability (Q51–Q75): Covers Cpk (Process
Capability), Control Charts (p, c, x-bar, R), and identifying Assignable vs. Common
Cause variation.
3. Capacity & Location Planning (Q76–Q100): Focuses on Design vs. Effective
Capacity, Capacity Cushions, and Service vs. Manufacturing location factors.
4. Inventory Management & MRP (Q101–Q130): Covers EOQ, ABC Analysis, Reorder
Points, and the "Netting" process in Material Requirements Planning.
5. Lean Systems & JIT (Q131–Q150): Focuses on Kanban "Pull" systems, reducing
waste (Muda), and the importance of preventive maintenance.
6. Supply Chain & Global Logistics (Q151–Q175): Covers Vertical vs. Horizontal
Integration, the Bullwhip Effect, 3PL providers, and C-TPAT security.
7. Project Management & Scheduling (Q176–Q200): Focuses on the Critical Path (Zero
Slack), PERT/CPM, Sequencing Rules (SPT, EDD), and the Theory of Constraints
(TOC).
Pro-Tip for the OA:
Q1: Which definition of quality evaluates how well a product performs its
intended function?
,o A. Conformance to specifications
o B. Fitness for use
o C. Value for price paid
o D. Psychological criteria
o Explanation: Fitness for use focuses on the user's perspective—specifically,
whether the product fulfills the purpose for which it was purchased.
Q2: Which TQM pioneer is responsible for the "14 Points" and emphasized that
management is responsible for 85% of quality problems?
o A. Joseph Juran
o B. W. Edwards Deming
o C. Philip Crosby
o D. Kaoru Ishikawa
o Explanation: Deming's 14 Points are foundational to TQM, highlighting that
system failures (managed by leadership) are the root of most defects.
Q3: Which quality cost category includes the costs of inspecting and testing
products to ensure they meet requirements?
o A. Internal failure costs
o B. Appraisal costs
o C. Prevention costs
o D. External failure costs
o Explanation: Appraisal costs are incurred during the process of uncovering
defects, such as lab testing or inspector salaries.
Q4: A company uses a visual tool to identify the "vital few" causes of defects
versus the "useful many." What is this tool called?
o A. Fishbone Diagram
o B. Flowchart
,o C. Pareto Analysis
o D. Control Chart
o Explanation: Pareto Analysis is based on the 80/20 rule, showing that 80% of
problems usually stem from 20% of the causes.
Q5: What is the primary purpose of a "Capacity Cushion"?
o A. To eliminate the need for preventive maintenance.
o B. To reduce the cost of raw materials.
o C. To provide reserve capacity for sudden increases in demand.
o D. To ensure the facility always operates at 100% utilization.
o Explanation: A capacity cushion is the amount of capacity in excess of expected
demand, allowing for flexibility during spikes.
Q6: In the DMAIC process of Six Sigma, which step is focused on identifying the
root cause of defects?
o A. Measure
o B. Analyze
o C. Improve
o D. Define
o Explanation: The Analyze phase of Six Sigma involves using statistical tools to
determine exactly why defects are occurring.
Q7: Which term describes the maximum output rate that can be achieved under
normal, realistic conditions (not ideal)?
o A. Design Capacity
o B. Effective Capacity
o C. Theoretical Capacity
o D. Maximum Utilization
, o Explanation: Effective capacity accounts for real-world constraints like
maintenance, breaks, and shifting schedules.
Q8: If a process is "in statistical control," it means:
o A. There are no defects being produced.
o B. The process is meeting all customer specifications.
o C. Variation is due only to common (random) causes.
o D. Assignable causes have been maximized.
o Explanation: Statistical control means the process is predictable and free from
"special" or "assignable" sources of variation.
Q9: Which layout type is best suited for a "job shop" environment with low-
volume, highly customized products?
o B. Process Layout
o A. Product Layout
o C. Fixed-position Layout
o D. Assembly Line
o Explanation: A process layout groups similar machines or functions together,
offering the flexibility needed for custom orders.
Q10: What is the most critical factor for the successful implementation of Total
Quality Management (TQM)?
o A. High-speed automation
o B. Lowest possible labor costs
o C. Top management commitment
o D. Large inventory buffers
o Explanation: TQM is a cultural shift that fails without the support and resource
allocation of senior leadership.
