Financial Management for Project Managers Inventory Management 2 — Questions and Answers
Question 1: A project manager notices that holding costs for raw materials represent 28% of unit value annually. Which inventory strategy would most directly reduce this cost?
- Increase safety stock levels
- Implement Just-In-Time (JIT) delivery (Correct answer)
- Switch to FIFO valuation method
- Extend payment terms with suppliers
Correct answer: Implement Just-In-Time (JIT) delivery
JIT delivery minimizes on-hand inventory, directly reducing holding costs such as storage, insurance, and capital tied up in stock.
Question 2: In the Economic Order Quantity (EOQ) model, what happens to the optimal order quantity if annual demand doubles?
- It doubles
- It quadruples
- It increases by approximately 41% (Correct answer)
- It remains unchanged
Correct answer: It increases by approximately 41%
EOQ is proportional to the square root of demand, so doubling demand multiplies EOQ by √2 ≈ 1.41, a 41% increase.
Question 3: Which inventory valuation method results in the highest net income during a period of rising prices?
- LIFO
- FIFO (Correct answer)
- Weighted Average Cost
- Specific Identification
Correct answer: FIFO
FIFO assigns lower (older) costs to COGS during rising prices, leaving higher-cost items in ending inventory and resulting in higher reported net income.
Question 4: A project has a reorder point of 500 units and an average daily usage of 50 units. What is the implied lead time in days?
- 5 days
- 10 days (Correct answer)
- 25 days
- 50 days
Correct answer: 10 days
Reorder Point = Average Daily Usage × Lead Time, so Lead Time = 500 ÷ 50 = 10 days.
Question 5: What does a high inventory turnover ratio relative to industry benchmarks typically indicate?
- Excessive safety stock
- Efficient inventory management or strong sales (Correct answer)
- Poor supplier relationships
- High carrying costs
Correct answer: Efficient inventory management or strong sales
A high turnover ratio means inventory is sold and replaced quickly, indicating efficient operations or robust demand.
Question 6: In ABC inventory analysis, which category typically represents the smallest percentage of SKUs but the highest percentage of annual inventory value?
- Category C
- Category B
- Category A (Correct answer)
- Category D
Correct answer: Category A
Category A items are typically 10-20% of SKUs but account for 70-80% of total inventory value, warranting the tightest controls.
Question 7: A project manager is evaluating whether to place one large order or several smaller orders. Which cost component favors placing fewer, larger orders?
- Holding costs
- Ordering costs (Correct answer)
- Shortage costs
- Quality inspection costs
Correct answer: Ordering costs
Ordering costs (setup, processing, freight per order) are incurred each time an order is placed, so fewer orders reduce total ordering costs.
