Question 1: A company's supply chain strategy must be aligned with its overall
business strategy. Which of the following competitive priorities is MOST
directly supported by a supply chain designed for high levels of product
availability and rapid response?
A. Cost leadership
B. Product differentiation
C. Delivery and flexibility
D. Quality leadership
CORRECT ANSWER: C. Delivery and flexibility
Rationale: A supply chain designed for high availability and rapid response directly
supports the competitive priorities of delivery (speed and reliability) and flexibility
(ability to adapt to changes in demand or product mix). While cost leadership focuses on
minimizing expenses, differentiation on creating unique products, and quality leadership
on superior performance, these are not the primary direct outcomes of a high-
availability, responsive supply chain design.
Question 2: In the context of Sales and Operations Planning (S&OP), what is
the PRIMARY purpose of the demand review meeting?
A. To finalize the production schedule
B. To validate the independent demand forecast
C. To approve capital expenditures
D. To resolve supplier quality issues
CORRECT ANSWER: B. To validate the independent demand forecast
Rationale: The demand review meeting in the S&OP process focuses on the demand
side of the business. Its primary purpose is to validate the independent demand
forecast, which is a crucial input for the subsequent supply review and financial
integration. The production schedule is finalized later, capital expenditures are a
separate financial process, and supplier quality is typically addressed in procurement or
operational meetings.
,Question 3: A master scheduler is reviewing the MPS for a new product. The
product has a planning time fence and a demand time fence. A customer order
is received for delivery within the demand time fence. How should the master
scheduler typically respond to this order?
A. Reject the order
B. Change the MPS using the order as the primary driver
C. Accept the order and attempt to fulfill it from available stock
D. Accept the order and freeze the MPS for the entire horizon
CORRECT ANSWER: C. Accept the order and attempt to fulfill it from available
stock
Rationale: The demand time fence (DTF) is the period inside which the MPS is
considered firm and changes are very costly. Customer orders inside this fence are
typically accepted only if the product is available in stock or in a very advanced stage of
production. The MPS should not be changed to accommodate the order, as this would
cause major disruptions, and rejecting the order is not the first course of action.
Question 4: Which of the following statements accurately describes the
primary relationship between the Master Production Schedule (MPS) and
Material Requirements Planning (MRP)?
A. The MPS drives the MRP explosion.
B. MRP is the input to the MPS.
C. The MPS and MRP are two terms for the same process.
D. MRP is a long-term plan, while MPS is a short-term execution plan.
CORRECT ANSWER: A. The MPS drives the MRP explosion.
Rationale: The Master Production Schedule (MPS) defines what end items need to be
produced, in what quantities, and when. The Material Requirements Planning (MRP)
system takes this MPS as its primary input and "explodes" it using the Bill of Materials
(BOM) to calculate the timing and quantities of all subassemblies, components, and raw
materials required to meet the MPS.
Question 5: A company uses a periodic review system to manage inventory.
Which of the following is a key characteristic of this system?
A. A fixed order quantity is placed each time a review is conducted.
B. The time between orders is variable.
C. The order quantity varies to bring the inventory level up to a predetermined
maximum.
D. The system requires a perpetual inventory tracking system.
CORRECT ANSWER: C. The order quantity varies to bring the inventory level
up to a predetermined maximum.
Rationale: In a periodic review system (also known as a fixed-interval system),
inventory is counted at fixed time intervals. The order quantity at each review is not
,fixed; instead, it is the difference between a predetermined maximum inventory level
(often called a "target level" or "order-up-to level") and the current inventory position.
This characteristic differentiates it from a fixed-order quantity system.
Question 6: A manufacturer of medical devices wants to ensure high levels of
quality and minimize defects. Which philosophy would be MOST applicable in
this context?
A. Just-In-Time (JIT)
B. Theory of Constraints (TOC)
C. Six Sigma
D. Mass Customization
CORRECT ANSWER: C. Six Sigma
Rationale: Six Sigma is a data-driven methodology and philosophy focused on
reducing process variation and defects to near-zero levels. It is particularly suited for
industries like medical devices where quality and reliability are critical. JIT focuses on
waste reduction, TOC on managing bottlenecks, and mass customization on producing
high variety at low cost, but Six Sigma is most directly associated with defect
minimization.
Question 7: In the Theory of Constraints (TOC), which step should be taken
after the constraint has been elevated (i.e., improved)?
A. Subordinate everything to the constraint.
B. Identify the constraint.
C. Reduce the impact of the constraint by offloading work.
D. Go back to the first step and find the new constraint.
CORRECT ANSWER: D. Go back to the first step and find the new constraint.
Rationale: The five focusing steps of the Theory of Constraints are: 1) Identify the
constraint, 2) Exploit the constraint, 3) Subordinate everything else to the constraint, 4)
Elevate the constraint, and 5) Repeat the process. Once the constraint is elevated
(broken), it is no longer the constraint, so the process cycles back to identify the new
constraint.
Question 8: Which of the following is a primary advantage of implementing a
pull-based production system like Kanban?
A. It is ideal for highly customized products.
B. It minimizes work-in-process (WIP) inventory.
C. It requires sophisticated forecasting tools.
D. It eliminates the need for a master schedule.
CORRECT ANSWER: B. It minimizes work-in-process (WIP) inventory.
Rationale: A pull-based system like Kanban is driven by actual customer consumption.
Production is triggered only when there is demand for a specific item, which works to
, limit and minimize Work-In-Process (WIP) inventory. It is less suited for highly
customized products and still relies on a master schedule for overall capacity and
material planning.
Question 9: What is the direct consequence of the bullwhip effect in a supply
chain?
A. Increased product variety.
B. Reduced inventory holding costs throughout the chain.
C. Amplified demand variability as you move upstream.
D. Improved supplier relationships.
CORRECT ANSWER: C. Amplified demand variability as you move upstream.
Rationale: The bullwhip effect refers to the phenomenon where small fluctuations in
demand at the consumer level lead to increasingly larger fluctuations in demand as you
move upstream in the supply chain (e.g., from retailer to wholesaler to manufacturer).
This amplification results from various factors like order batching, price fluctuations, and
lack of information sharing.
Question 10: A master scheduler is calculating the available-to-promise (ATP)
quantity for a new order. Which of the following best defines ATP?
A. The capacity available in a work center.
B. The uncommitted inventory that can be promised to a customer.
C. The maximum production rate in a given period.
D. The total amount of inventory on hand.
CORRECT ANSWER: B. The uncommitted inventory that can be promised to a
customer.
Rationale: Available-to-Promise (ATP) is a key output of the Master Production
Schedule. It represents the quantity of a specific item that is either on hand or scheduled
to be produced and is not already committed to existing customer orders. This ATP
quantity is used to make accurate delivery promises to customers. It is not about
capacity, production rate, or total inventory on hand.
Question 11: In Material Requirements Planning (MRP), what is the function of
the 'pegging' feature?
A. To calculate the economic order quantity for a component.
B. To determine the source of a requirement for a component.
C. To schedule the production of a work order.
D. To track the physical location of inventory.
CORRECT ANSWER: B. To determine the source of a requirement for a
component.
Rationale: Pegging is a crucial capability of MRP. It allows a planner to trace a specific
requirement for a component (a planned order or work order) back to its "parent," such
