Question 1: A company's strategic plan is translated into aggregate production
rates. Which of the following planning processes is primarily concerned with
converting the business plan into production and capacity plans for product
families?
A. Material Requirements Planning (MRP)
B. Sales and Operations Planning (S&OP)
C. Production Activity Control (PAC)
D. Master Production Scheduling (MPS)
CORRECT ANSWER: B. Sales and Operations Planning (S&OP)
Rationale: Sales and Operations Planning (S&OP) is the process that takes the strategic
business plan and translates it into aggregate production and capacity plans for product
families. It reconciles demand plans with supply capabilities at the aggregate level,
ensuring that the company's overall strategy is executable from a production and
inventory standpoint. While MRP, MPS, and PAC are all detailed planning and execution
tools, S&OP is the higher-level process that bridges strategic and operational planning .
Question 2: A planner is calculating the economic order quantity (EOQ) for a
component. Which of the following costs must be balanced to determine the
optimal order quantity?
A. Carrying costs and shortage costs
B. Ordering costs and carrying costs
C. Purchase costs and quality costs
D. Transportation costs and setup costs
CORRECT ANSWER: B. Ordering costs and carrying costs
Rationale: The Economic Order Quantity (EOQ) model is a classic inventory
management formula that identifies the optimal order quantity by balancing ordering
costs (or setup costs) against carrying costs (or holding costs). The goal is to minimize
the total inventory cost by finding the point where these two opposing costs are equal.
Shortage, purchase, and transportation costs are important but are not the primary costs
balanced in the fundamental EOQ model.
Question 3: Which of the following is the primary purpose of a "time fence" in
the context of a Master Production Schedule (MPS)?
,A. To define the maximum lead time for purchased materials.
B. To establish a period where changes to the MPS are restricted to maintain stability.
C. To calculate the minimum order quantity for a specific product.
D. To separate planning for make-to-order items from make-to-stock items.
CORRECT ANSWER: B. To establish a period where changes to the MPS are
restricted to maintain stability.
Rationale: A time fence in an MPS is a point in time that sets a boundary or guideline
for scheduling activities. Inside the "frozen" or "slushy" zone, changes to the MPS are
heavily restricted or require significant management approval to prevent costly
disruptions to production and supply chain operations. This stability is crucial for
maintaining reliable delivery schedules and efficient capacity utilization .
Question 4: In the context of lean manufacturing, what does the term "muda"
refer to?
A. The continuous improvement of processes.
B. The level of inventory that cushions against uncertainty.
C. Any activity that consumes resources but does not add value for the customer.
D. The visual signal used in a pull production system.
CORRECT ANSWER: C. Any activity that consumes resources but does not add
value for the customer.
Rationale: "Muda" is a Japanese term for waste. In lean manufacturing, it refers to any
activity or process that uses resources (time, materials, labor) but does not create value
for the end customer. The identification and systematic elimination of muda (waste) is a
core principle of lean thinking, along with muri (overburden) and mura (unevenness).
Question 5: A manufacturer wants to ensure that a supplier is performing to
the agreed-upon quality and delivery standards. Which of the following
metrics is most directly used to monitor supplier performance in this way?
A. Inventory Turnover Ratio
B. Supplier On-Time Delivery Rate
C. Capacity Utilization Rate
D. Schedule Attainment
CORRECT ANSWER: B. Supplier On-Time Delivery Rate
Rationale: Supplier On-Time Delivery Rate is a direct metric that measures a supplier's
reliability in delivering goods as promised. It is a key performance indicator (KPI) used
in supplier scorecards and continuous improvement programs to monitor and manage
supplier performance regarding delivery schedules. Other metrics like Inventory
Turnover relate to internal performance, while Capacity Utilization measures internal
production usage.
Question 6: A company is evaluating the costs associated with holding
inventory. Which of the following is a component of inventory carrying costs?
,A. Cost of quality inspections.
B. Cost of order setup.
C. Cost of capital tied up in inventory.
D. Cost of transportation.
CORRECT ANSWER: C. Cost of capital tied up in inventory.
Rationale: Inventory carrying cost (or holding cost) is the total cost of holding
inventory. It includes the cost of capital (the opportunity cost of money invested in
inventory), storage costs, insurance, taxes, and costs associated with obsolescence and
shrinkage. Order setup, transportation, and quality inspections are not typically
classified as carrying costs; setup and transportation are ordering costs, and inspections
are quality-related costs.
Question 7: The primary objective of the "Plan and Manage Demand" module
in the CPIM framework is to:
A. Manage the physical distribution of finished goods.
B. Align the supply chain with the business strategy.
C. Forecast customer demand and translate it into a realistic plan.
D. Execute detailed production schedules on the shop floor.
CORRECT ANSWER: C. Forecast customer demand and translate it into a
realistic plan.
Rationale: The "Plan and Manage Demand" module focuses on the processes of
forecasting, demand management, and demand shaping. Its core objective is to develop
a reliable and actionable forecast of customer demand and then manage it effectively
through collaborative planning and other techniques to ensure the business can meet
customer requirements profitably .
Question 8: In Material Requirements Planning (MRP), what is a "planned
order receipt"?
A. A purchase order that has been sent to a supplier.
B. An order that has been released to the factory floor.
C. The quantity and timing of an order that is projected to be received in the future to
satisfy net requirements.
D. The order quantity calculated to be equal to the gross requirements.
CORRECT ANSWER: C. The quantity and timing of an order that is projected to
be received in the future to satisfy net requirements.
Rationale: In the MRP logic, "planned order receipts" are the quantities of an item that
are planned to be received at the beginning of a specific time period to cover the net
requirements. These are future projected receipts that have not yet been released as
orders. When the system "firms" or releases a planned order, it becomes a "scheduled
receipt."
, Question 9: Which of the following describes "backflushing" in inventory
management?
A. Expediting a late order to prevent a stockout.
B. The process of using actual component usage data to deduct inventory quantities.
C. Returning purchased goods to a supplier due to poor quality.
D. The method of counting inventory by physically verifying a sample of items.
CORRECT ANSWER: B. The process of using actual component usage data to
deduct inventory quantities.
Rationale: Backflushing is an inventory management technique where a system
automatically deducts the quantities of component parts from inventory records when a
finished product is reported as completed. It uses a bill of materials to determine the
components used. This method is often used in repetitive or lean manufacturing
environments to streamline transaction recording and avoid detailed tracking at every
production stage.
Question 10: What is the primary focus of "Production Activity Control" (PAC)?
A. Long-term capacity planning.
B. Strategic sourcing of raw materials.
C. The execution and control of work on the shop floor.
D. The physical warehousing and distribution of products.
CORRECT ANSWER: C. The execution and control of work on the shop floor.
Rationale: Production Activity Control (PAC) is the module responsible for the
execution and control of the production plan. It involves translating the MPS and MRP
plans into detailed daily and hourly schedules, dispatching work to production centers,
monitoring progress against these schedules, and providing feedback to ensure efficient
and timely completion of jobs .
Question 11: A company is choosing between two suppliers. Supplier A has a
lower unit price but longer lead times. Supplier B has a higher unit price but
shorter lead times. Which purchasing concept is most relevant to this
decision?
A. Economic Order Quantity (EOQ)
B. Total Cost of Ownership (TCO)
C. ABC Analysis
D. Pareto Principle
CORRECT ANSWER: B. Total Cost of Ownership (TCO)
Rationale: Total Cost of Ownership (TCO) is a purchasing concept used to determine
the total cost of acquiring and using a good or service from a supplier. It goes beyond
the unit price to include all costs associated with the purchase, such as transportation,
inventory carrying costs (due to lead times), quality issues, and administrative expenses.
