AND ANSWERS WITH RATIONALE ALREADY GRADED A+
ASSURED PASS
1. A manufacturing firm uses warehouses and shippers in their supply chain. At
which stage of the firm's inventory management system would the statement
"percentage of line items shipped on schedule" be used?
A) Raw materials inventory
B) Work-in-progress inventory
C) Finished goods inventory
D) Sold goods inventory
Correct Answer: C
Rationale: The performance measure "percentage of line items shipped on
schedule" applies to finished goods inventory. Finished goods represent completed
products ready for shipment to customers. On-time shipment directly affects
customer satisfaction, order fulfillment performance, and distribution efficiency.
Work-in-progress and raw materials inventories are internal to production and do
not involve customer shipment commitments.
2. Which factor determines how long it takes a qualified operator to perform a duty
of the job requirements under the assumption that the operator is working at a
sustainable pace with the proper tools for the process?
A) Observed time
B) Normal time
C) Performance time
D) Standard time
Correct Answer: D
Rationale: Standard time is the measure that determines how long it should take a
qualified operator to perform a job at a sustainable pace using proper tools and
methods. It includes normal time (observed time adjusted for performance rating)
plus allowances for fatigue, personal needs, and unavoidable delays. Standard time
is essential for scheduling work, determining labor requirements, and capacity
planning.
,3. A construction company produces furnished pre-fabricated manufactured
homes. The production manager has discovered challenges: production quantities
are low with only a small number of homes built efficiently, facility space limits
material handling, and employee workspace is constrained. Which hybrid layout
should be used?
A) Group technology
B) Process performance metrics
C) Manufacturing technology
D) Statistical reduction control
Correct Answer: A
Rationale: Group technology combines the efficiency of product layouts with the
flexibility of process layouts by grouping similar products into families and
arranging workstations into cells. For prefabricated homes with low production
volumes, shared product designs, constrained space, and minimal material
handling requirements, group technology reduces movement, setup times, work-in-
process inventory, and congestion.
4. Which two factors most significantly affect a service location decision?
A) Proximity to manufacturing centers
B) Proximity to customers
C) Warehouse storage capacity
D) Quality-of-life issues
Correct Answer: B and D
Rationale: For service organizations, proximity to customers and quality-of-life
issues are two dominant factors in location decisions. Service operations require
direct customer contact—being close to customers reduces travel time, improves
convenience, and enhances perceived service quality. Quality-of-life issues such as
education, healthcare, housing, safety, and climate affect the ability to attract and
retain skilled service employees.
5. What are two strategic objectives for every member of the supply chain?
A) Increasing cost effectiveness
B) Becoming more efficient
C) Reducing lead times
D) Increasing demand
Correct Answer: A and B
Rationale: Two universal strategic objectives for all supply chain members are
increasing cost effectiveness and becoming more efficient. Every organization in
the supply chain—suppliers, manufacturers, distributors, and retailers—must
manage costs while improving operational efficiency to remain competitive. Cost
,effectiveness ensures sustainable margins and competitive pricing, while efficiency
focuses on process improvement, waste reduction, and throughput enhancement.
6. A company is experiencing an unusual amount of deliveries that are either late
or incorrect quantity. Which element of the service-profit chain is being directly
affected by this issue?
A) Internal service quality
B) Employee satisfaction
C) Customer satisfaction
D) Revenue growth
Correct Answer: C
Rationale: Late or incorrect quantity deliveries directly affect customer
satisfaction. The service-profit chain demonstrates that customer satisfaction drives
loyalty, which in turn drives revenue growth and profitability. When deliveries are
unreliable, customers experience dissatisfaction, which may lead to lost business
and negative word-of-mouth. This issue stems from operational failures in the
supply chain.
7. A company is using a measure that determines how long it should take a
qualified operator to perform a duty of the job requirements. Which measure is
being used?
A) Observed time
B) Normal time
C) Standard time
D) Performance time
Correct Answer: C
Rationale: Standard time represents the time required for a qualified operator to
complete a task at a sustainable pace using proper methods and tools. It is
calculated by multiplying normal time by an allowance factor. Standard time is the
foundation for labor planning, production scheduling, cost estimation, and
establishing incentive systems. It reflects realistic expectations for job completion.
8. Which type of inventory management system utilizes a predetermined order
point and order quantity that remains constant regardless of demand fluctuations?
A) Fixed-order quantity system
B) Fixed-time period system
C) Just-in-time system
D) Vendor-managed inventory system
Correct Answer: A
, Rationale: A fixed-order quantity system (also called Q-system or reorder point
system) uses a predetermined order point and a fixed order quantity that does not
change with demand fluctuations. When inventory levels drop to the reorder point,
a specific quantity is ordered. This system provides consistent ordering and is
widely used due to its simplicity, despite demand variability.
9. Which type of operations management activity involves balancing the cost of
inventory with the cost of lost sales due to stockouts?
A) Supplier selection
B) Inventory management
C) Quality management
D) Capacity planning
Correct Answer: B
Rationale: Inventory management involves balancing the cost of holding inventory
(carrying costs, storage, insurance) with the cost of stockouts (lost sales, customer
dissatisfaction, lost goodwill). The economic order quantity and safety stock
calculations are fundamental to achieving this balance. Effective inventory
management minimizes total inventory costs while ensuring customer service
levels are maintained.
10. A hospital is implementing a new scheduling system to better match staffing
levels with patient demand. This is an example of which operations management
function?
A) Quality management
B) Capacity management
C) Inventory management
D) Supply chain management
Correct Answer: B
Rationale: Capacity management involves matching organizational capacity (such
as staffing levels) to customer demand. In healthcare, proper staffing is critical for
patient safety and satisfaction. Capacity management decisions include workforce
scheduling, facility planning, and equipment acquisition to ensure resources are
available when needed without excess idle time.
11. Which of the following is a primary benefit of implementing a just-in-time
(JIT) inventory system?
A) Increased safety stock levels
B) Reduced work-in-process inventory
C) Higher storage costs
D) Longer lead times
