APICS Sales & Operations Planning 4 — Questions and Answers
Question 1: A company notices its S&OP plan is consistently ignored at the operational level. What is the most likely root cause?
- The S&OP plan is not translated into detailed execution plans like MPS and MRP (Correct answer)
- The company has too many SKUs to manage
- The demand review is held too infrequently
- Finance is not included in the product review
Correct answer: The S&OP plan is not translated into detailed execution plans like MPS and MRP
Without cascading the S&OP plan into the Master Production Schedule (MPS) and Material Requirements Planning (MRP), shop floor execution remains disconnected from the S&OP decisions.
Question 2: Which of the following best characterizes an 'unconstrained' demand plan in S&OP?
- A forecast of what the market demands regardless of supply or capacity limitations (Correct answer)
- A forecast capped at the current production capacity
- A plan that excludes promotional demand spikes
- A budget-driven forecast set by finance
Correct answer: A forecast of what the market demands regardless of supply or capacity limitations
An unconstrained demand plan represents true market demand without internal constraints applied, serving as the starting point before supply limitations are considered.
Question 3: In S&OP, what is the purpose of tracking 'plan vs. actual' performance each month?
- To identify forecast bias and process gaps so the S&OP cycle can be improved (Correct answer)
- To evaluate individual salesperson bonuses
- To set new pricing for the next fiscal year
- To replace the need for a statistical forecasting model
Correct answer: To identify forecast bias and process gaps so the S&OP cycle can be improved
Comparing plan to actual highlights systemic biases, process failures, and assumption errors that should feed back into improving the next S&OP cycle.
Question 4: Which of the following scenarios would most likely trigger an 'exception' flag in an S&OP system?
- Forecasted demand for a product exceeds available production capacity by 40% (Correct answer)
- A product's demand is exactly equal to the prior year
- A supplier delivers on time at the agreed price
- Inventory levels are within the target safety stock range
Correct answer: Forecasted demand for a product exceeds available production capacity by 40%
A large gap between forecasted demand and available supply capacity is a critical exception that requires management attention and resolution in the S&OP process.
Question 5: What does 'inventory optimization' in the context of S&OP primarily aim to achieve?
- Setting inventory targets that balance customer service levels against carrying costs (Correct answer)
- Eliminating all finished goods warehouses
- Maximizing production output regardless of demand
- Reducing the number of suppliers to simplify procurement
Correct answer: Setting inventory targets that balance customer service levels against carrying costs
Inventory optimization in S&OP determines the right amount of stock at each node to meet service level targets at the lowest total cost.
Question 6: A seasonal business uses S&OP to plan inventory buildup before peak demand. This strategy is called:
- Level production strategy (Correct answer)
- Chase demand strategy
- Make-to-order strategy
- Postponement strategy
Correct answer: Level production strategy
A level production strategy maintains a stable production rate and builds inventory ahead of demand peaks, which is common in seasonal businesses using S&OP.
Question 7: Which of the following is a primary benefit of a well-executed S&OP process?
- Improved alignment between business strategy and day-to-day operations (Correct answer)
- Elimination of all supply chain variability
- Reduction of the product portfolio to a single SKU
- Removal of the need for safety stock
Correct answer: Improved alignment between business strategy and day-to-day operations
S&OP bridges strategic intent and operational execution by creating a single, agreed plan that all functions use to make decisions.
