APICS Sales & Operations Planning 2 — Questions and Answers
Question 1: Which metric is most commonly used to measure S&OP forecast accuracy?
- Mean Absolute Percentage Error (MAPE) (Correct answer)
- Economic Order Quantity (EOQ)
- Days Sales Outstanding (DSO)
- Return on Assets (ROA)
Correct answer: Mean Absolute Percentage Error (MAPE)
MAPE measures the average absolute percentage difference between forecasted and actual demand, making it the standard S&OP forecast accuracy metric.
Question 2: In S&OP, what is the primary purpose of the 'pre-S&OP' meeting?
- To resolve functional disagreements before the executive meeting (Correct answer)
- To set annual financial budgets
- To approve new product launches
- To conduct supplier negotiations
Correct answer: To resolve functional disagreements before the executive meeting
The pre-S&OP meeting allows functional leaders to reconcile differences and present a unified view to executives, avoiding unproductive debate at the executive session.
Question 3: A company's S&OP process shows demand exceeding supply capacity for the next three months. Which response is most appropriate?
- Prioritize customers, adjust pricing, or add capacity (Correct answer)
- Immediately cancel all low-margin orders
- Delay the S&OP cycle until capacity is resolved
- Outsource the entire production operation
Correct answer: Prioritize customers, adjust pricing, or add capacity
When demand exceeds supply, S&OP should evaluate options like demand shaping, customer prioritization, overtime, or capacity additions to close the gap.
Question 4: What distinguishes Integrated Business Planning (IBP) from traditional S&OP?
- IBP integrates financial planning and strategic plans more deeply into the process (Correct answer)
- IBP focuses only on short-term operational scheduling
- IBP eliminates the need for a demand review
- IBP replaces ERP systems
Correct answer: IBP integrates financial planning and strategic plans more deeply into the process
IBP extends S&OP by fully integrating financial plans, strategic initiatives, and portfolio management into a single monthly business management process.
Question 5: Which of the following best describes 'demand shaping' in the context of S&OP?
- Using pricing, promotions, or product mix to influence demand toward supply availability (Correct answer)
- Adjusting production schedules to match historical demand patterns
- Reducing safety stock to cut inventory costs
- Reallocating warehouse space to match peak seasons
Correct answer: Using pricing, promotions, or product mix to influence demand toward supply availability
Demand shaping uses commercial levers such as pricing, promotions, and channel incentives to move demand toward what supply can profitably fulfill.
Question 6: In an S&OP process, the 'supply review' step is primarily responsible for:
- Assessing the ability to meet the demand plan given current capacity and materials (Correct answer)
- Setting the sales targets for the upcoming quarter
- Approving capital expenditure for new equipment
- Reconciling accounts payable with vendor invoices
Correct answer: Assessing the ability to meet the demand plan given current capacity and materials
The supply review evaluates capacity constraints, material availability, and lead times to determine if and how the demand plan can be met.
Question 7: Which planning horizon is most typical for an S&OP process?
- 18 to 24 months rolling (Correct answer)
- 1 to 4 weeks
- 5 to 10 years
- 3 to 5 days
Correct answer: 18 to 24 months rolling
S&OP typically covers an 18–24 month rolling horizon to allow enough time to identify capacity gaps and take corrective action.
