CPM P&L Ownership & Cost Reduction 2 â Questions and Answers
Question 1: A plant manager notices that the cost of goods sold (COGS) as a percentage of revenue has crept from 62% to 68% over six months. Which action most directly addresses this variance?
- Increase the sales price to restore the gross margin percentage
- Conduct a root-cause analysis on material, labor, and overhead cost drivers (Correct answer)
- Reduce the SG&A budget to offset the COGS increase
- Defer capital maintenance to free up cash
Correct answer: Conduct a root-cause analysis on material, labor, and overhead cost drivers
A root-cause analysis on the three COGS componentsâmaterial, labor, and overheadâpinpoints the specific driver(s) before corrective action is taken.
Question 2: Which financial metric best measures how efficiently a plant converts revenue into operating profit, excluding interest and taxes?
- Gross margin percentage
- EBITDA margin
- Operating (EBIT) margin (Correct answer)
- Net profit margin
Correct answer: Operating (EBIT) margin
Operating (EBIT) marginâoperating income divided by revenueâreflects the plant's core profitability after all operating costs but before financing and tax effects.
Question 3: During a budget review, a plant manager finds that actual overhead absorption is $120,000 under-absorbed versus the standard. The most likely cause is:
- Actual production volume was higher than the budgeted volume used to set the overhead rate
- Actual production volume was lower than the budgeted volume used to set the overhead rate (Correct answer)
- Direct material prices fell below standard
- Direct labor efficiency improved beyond standard
Correct answer: Actual production volume was lower than the budgeted volume used to set the overhead rate
Under-absorption occurs when actual production volume is lower than planned, so fixed overhead is spread over fewer units than the rate assumed.
Question 4: A plant manager wants to reduce conversion costs by 5% without affecting output. Which lever typically yields the fastest results?
- Renegotiating long-term supply contracts
- Eliminating non-value-added steps in the production process through a kaizen event (Correct answer)
- Investing in new automated equipment
- Outsourcing the entire production line
Correct answer: Eliminating non-value-added steps in the production process through a kaizen event
Kaizen events can rapidly eliminate waste and non-value-added activities, reducing conversion costs quickly without major capital investment.
Question 5: On a plant P&L, depreciation of manufacturing equipment is classified as:
- A selling, general, and administrative (SG&A) expense
- A below-the-line financing cost
- A product cost included in overhead and ultimately in COGS (Correct answer)
- A period cost expensed directly to net income
Correct answer: A product cost included in overhead and ultimately in COGS
Manufacturing equipment depreciation is a product (inventoriable) cost that flows through overhead, into WIP, then finished goods, and finally COGS when product is sold.
Question 6: A plant manager commits to a $2M cost reduction target. After six months, $800K has been realized. What should the manager report to leadership?
- The full $2M as achieved because the plan is on track
- $800K realized, $1.2M in pipeline with revised timing and confidence levels (Correct answer)
- Only the $2M target, without progress detail, to maintain credibility
- $800K realized and request a target reduction to match the run rate
Correct answer: $800K realized, $1.2M in pipeline with revised timing and confidence levels
Transparent reporting of realized savings alongside pipeline status and confidence levels enables leadership to make informed decisions and allows timely corrective action.
Question 7: Which cost reduction strategy carries the highest risk of negatively impacting product quality and customer satisfaction?
- Implementing energy efficiency projects
- Reducing direct material specifications below engineering minimums to lower unit cost (Correct answer)
- Cross-training operators to reduce overtime costs
- Consolidating vendor spend to achieve volume discounts
Correct answer: Reducing direct material specifications below engineering minimums to lower unit cost
Cutting material specifications below engineered minimums can compromise product integrity, leading to defects, returns, warranty claims, and customer attrition.
