Question 1: In the context of aligning the supply chain with business strategy,
which of the following competitive priorities is MOST associated with a
company that offers a wide variety of product options?
A. Cost leadership
B. Delivery speed
C. Flexibility
D. Quality
CORRECT ANSWER: C. Flexibility
Rationale: Flexibility as a competitive priority focuses on a company's ability to offer a
wide range of products or options and to adapt to changes in customer preferences.
Cost leadership focuses on being the lowest-cost producer, delivery speed on rapid
fulfillment, and quality on product reliability and performance. Offering a wide variety is
a direct measure of product flexibility.
Question 2: In a make-to-order (MTO) environment, when does the company
typically commit to a specific delivery date?
A. At the time of the customer order entry
B. After the master production schedule (MPS) is run for the period
C. When the bill of materials (BOM) is finalized
D. Upon receipt of raw materials
CORRECT ANSWER: A. At the time of the customer order entry
Rationale: In a make-to-order environment, the product is not produced until a
customer order is received. The delivery date commitment is a critical part of the order
entry process and is based on current capacity and material availability. The MPS run
occurs after the order is received, the BOM is created from the order specifications, and
raw material receipt is a downstream activity.
Question 3: What is the primary purpose of Sales and Operations Planning
(S&OP)?
A. To create a detailed daily production schedule for the plant floor
B. To balance demand and supply at an aggregate level and align it with business
strategy
,C. To manage the procurement of raw materials from suppliers
D. To track individual employee productivity metrics
CORRECT ANSWER: B. To balance demand and supply at an aggregate level
and align it with business strategy
Rationale: S&OP is a strategic, executive-level process that balances demand and
supply at the aggregate level (product families). Its main goal is to ensure that
operational plans are aligned with the overall business strategy . Detailed scheduling (A)
is a different process, procurement (C) is a function of supply management, and
employee productivity tracking (D) is not a primary purpose of S&OP.
Question 4: Which of the following is a key metric used to measure forecast
accuracy?
A. Economic Order Quantity (EOQ)
B. Mean Absolute Deviation (MAD)
C. Reorder Point (ROP)
D. Days of Inventory Outstanding (DIO)
CORRECT ANSWER: B. Mean Absolute Deviation (MAD)
Rationale: Mean Absolute Deviation (MAD) is a standard metric used to measure the
accuracy of a forecast by calculating the average absolute error between the forecast
and the actual demand . EOQ is a lot-sizing calculation, ROP is a trigger for
replenishment, and DIO is a measure of how long a company holds inventory.
Question 5: Which of the following best describes the Bullwhip Effect in a
supply chain?
A. A strategy to increase inventory levels to meet a surge in demand
B. A phenomenon where small fluctuations in demand at the retail level cause larger and
larger fluctuations in orders as they move up the supply chain
C. The process of efficiently shipping products directly to the end customer
D. A method for calculating the optimal number of suppliers
CORRECT ANSWER: B. A phenomenon where small fluctuations in demand at
the retail level cause larger and larger fluctuations in orders as they move up
the supply chain
Rationale: The bullwhip effect is a well-known supply chain phenomenon where
demand variability is amplified as orders are passed from downstream (retail) to
upstream (supplier) partners . This leads to inefficiencies and increased costs. The other
options describe different concepts in inventory, logistics, and sourcing.
Question 6: What is the primary function of the Master Production Schedule
(MPS)?
A. To calculate the net requirements for all component parts
B. To determine the purchasing and production orders for the next period
,C. To schedule the production of end items or major subassemblies to meet demand
D. To manage the flow of materials through the warehouse
CORRECT ANSWER: C. To schedule the production of end items or major
subassemblies to meet demand
Rationale: The Master Production Schedule (MPS) is a plan for the production of end
items (in a make-to-stock environment) or major subassemblies (in an assemble-to-order
environment) over a specific time horizon. It disaggregates the aggregate plan into
specific product families or items. Material Requirements Planning (A and B) uses the
MPS as its primary input. Warehouse management (D) is a separate function.
Question 7: A company is planning its inventory levels. Which type of
inventory is referred to as "buffer stock" to protect against uncertainties in
demand or supply?
A. Cycle stock
B. Pipeline stock
C. Safety stock
D. Speculative stock
CORRECT ANSWER: C. Safety stock
Rationale: Safety stock is extra inventory held to mitigate the risk of stockouts caused
by fluctuations in customer demand or uncertainties in supplier lead times. It acts as a
buffer . Cycle stock is inventory held to meet average demand between orders; pipeline
stock is inventory in transit; and speculative stock is purchased to hedge against price
increases or shortages.
Question 8: Which planning horizon is typically addressed by an Aggregate
Production Plan?
A. A few days to a week
B. One to three months
C. Six to eighteen months
D. Three to five years
CORRECT ANSWER: C. Six to eighteen months
Rationale: The aggregate plan is a medium-range plan that usually covers a time
horizon of 6 to 18 months. It is more detailed than the long-term strategic plan but less
detailed than the short-term master production schedule. The goal is to effectively
manage workforce levels, production rates, and inventory levels to meet aggregate
demand.
Question 9: In Material Requirements Planning (MRP), what is the key piece of
information that links the MPS to the component procurement and production
orders?
, A. The production schedule
B. The bill of materials (BOM)
C. The capacity plan
D. The inventory record
CORRECT ANSWER: B. The bill of materials (BOM)
Rationale: The Bill of Materials (BOM) is a structured list of all the components,
subassemblies, and raw materials required to manufacture a finished product. In MRP,
the BOM is used to "explode" the MPS requirements into the gross requirements for all
lower-level items, thereby linking the end-item demand to the component procurement
and production orders.
Question 10: Which of the following is a method used to control a pull system
in lean manufacturing?
A. The Economic Order Quantity formula
B. Kanban cards
C. Safety stock calculations
D. Fixed order intervals
CORRECT ANSWER: B. Kanban cards
Rationale: A pull system signals production only when there is demand, moving
material "as needed" rather than "just in case." Kanban cards are the most recognizable
visual signal used in a pull system to authorize the production or movement of items .
EOQ, safety stock, and fixed intervals are elements of traditional push-based
replenishment systems.
Question 11: What is the main objective of capacity requirements planning
(CRP)?
A. To calculate the total cost of a product
B. To determine the amount of labor required for a specific job
C. To compare the planned capacity with the capacity needed to execute the MPS
D. To forecast future demand for the company's products
CORRECT ANSWER: C. To compare the planned capacity with the capacity
needed to execute the MPS
Rationale: Capacity Requirements Planning (CRP) is a short-term capacity planning
technique. It takes the planned orders from the MPS and MRP and determines if there is
enough capacity at critical work centers to execute those plans. It provides a detailed
match between planned output and available capacity.
Question 12: When using a moving average for forecasting demand, what effect
does a larger number of periods have on the forecast?
A. It makes the forecast more responsive to recent changes.
B. It smooths out the forecast more and reduces the impact of random fluctuations.
