CPIM Sales and Operations Planning 5 — Questions and Answers
Question 1: Which KPI would BEST measure the effectiveness of the S&OP process itself (rather than a supply chain outcome)?
- Percentage of S&OP decisions implemented as approved (Correct answer)
- On-time delivery rate to customers
- Gross margin percentage by product line
- Total inventory value in the warehouse
Correct answer: Percentage of S&OP decisions implemented as approved
Tracking whether approved S&OP decisions are actually executed measures process discipline and organizational adherence to the plan.
Question 2: A company sells products with highly seasonal demand. Which S&OP inventory strategy is MOST appropriate?
- Build seasonal inventory in advance during low-demand periods using a level production strategy (Correct answer)
- Hire and lay off workers each month to exactly match demand
- Carry zero finished-goods inventory and rely solely on subcontracting at peak
- Reduce the planning horizon to one month to improve accuracy
Correct answer: Build seasonal inventory in advance during low-demand periods using a level production strategy
Pre-building inventory during the off-season with level production smooths workforce and capacity costs while ensuring product availability at peak demand.
Question 3: In the S&OP process, 'management business review' or 'executive S&OP' is convened to:
- Make final decisions on unresolved supply-demand gaps and approve the operating plan (Correct answer)
- Generate the initial statistical demand forecast for the upcoming cycle
- Review individual customer orders and delivery schedules
- Update the ERP system with confirmed production quantities
Correct answer: Make final decisions on unresolved supply-demand gaps and approve the operating plan
The executive S&OP session is where senior leadership resolves escalated trade-offs, approves the plan, and allocates resources across the business.
Question 4: Which action BEST supports continuous improvement of the S&OP process over time?
- Conducting regular performance reviews comparing plan versus actual results and acting on gaps (Correct answer)
- Locking the S&OP template and process steps after the first successful cycle
- Limiting S&OP participation to supply chain and finance only
- Running S&OP quarterly instead of monthly to reduce overhead
Correct answer: Conducting regular performance reviews comparing plan versus actual results and acting on gaps
Systematic plan-versus-actual review exposes recurring gaps, drives root-cause analysis, and provides the feedback loop needed to improve forecast accuracy and planning quality.
Question 5: When a new product launch is included in the S&OP plan, the GREATEST forecasting challenge is typically:
- Lack of historical sales data to build a statistical baseline (Correct answer)
- Excess manufacturing capacity that is hard to redeploy
- Conflicts between the sales team and the logistics team
- Difficulty setting a retail price without competitive benchmarks
Correct answer: Lack of historical sales data to build a statistical baseline
New products have no demand history, so planners must rely on market research, analogous product data, and management judgment rather than statistical models.
Question 6: In S&OP, 'demand shaping' refers to:
- Using pricing, promotions, or lead-time incentives to influence customer demand toward available supply (Correct answer)
- Adjusting the statistical forecast downward to match capacity constraints
- Cleansing historical demand data to remove outliers before forecasting
- Segmenting customers by order size to prioritize fulfillment
Correct answer: Using pricing, promotions, or lead-time incentives to influence customer demand toward available supply
Demand shaping proactively influences buying behavior—through price incentives, promotions, or alternative products—to better match demand to available supply capacity.
Question 7: Which of the following BEST describes the relationship between S&OP and master production scheduling (MPS)?
- S&OP provides the aggregate family-level plan that MPS disaggregates into specific items and time periods (Correct answer)
- MPS is a strategic plan that drives the S&OP process from the top down
- S&OP and MPS are the same process operating at different frequencies
- MPS replaces S&OP once a company implements an ERP system
Correct answer: S&OP provides the aggregate family-level plan that MPS disaggregates into specific items and time periods
S&OP operates at the aggregate product-family level over a long horizon; MPS translates that approved plan into specific end-item schedules for detailed execution.
