1. How does integrated planning help balance demand and supply?
Ans:
Integrated planning connects demand forecasts, supply capabilities, inventory requirements, and business objectives. Teams can compare expected demand with available resources, identify supply constraints, and evaluate alternative plans. This coordination supports informed decisions about purchasing, production, inventory, and customer service priorities.
2. How would you compare alternative supply plans for a business?
Ans:
Evaluate each option against material availability, procurement costs, production capacity, delivery commitments, and supply risks. Check the assumptions used in each scenario and estimate the effect on service levels and inventory. Recommend a plan that meets business priorities while balancing cost and operational feasibility.
3. How can sales and operations planning improve resource allocation?
Ans:
Sales and operations planning brings together demand expectations, supply constraints, inventory positions, and financial objectives. It helps teams identify mismatches between demand and capacity and agree on priorities across departments. Regular reviews support coordinated purchasing, production, and distribution decisions.
4. How would you determine suitable buffer inventory for a critical material?
Ans:
Consider demand variation, supplier reliability, replenishment time, forecast accuracy, and the consequences of a stockout. Review service requirements and the cost of holding additional inventory. Monitor actual shortages and excess stock to decide whether the buffer level needs adjustment.
5. How can forecasting bias affect supply chain performance?
Ans:
Consistently overestimating demand can increase surplus inventory and purchasing costs, while underestimating demand can lead to shortages and missed deliveries. Compare forecasts with actual consumption across products and periods. Investigate systematic differences, improve forecast assumptions, and monitor accuracy after adjustments.
6. What would you investigate if an SAP IBP planning job failed?
Ans:
Review the job status, execution logs, planning configuration, and required input data. Check for missing information, invalid settings, integration problems, or authorisation issues. Correct the identified cause, rerun the process according to established procedures, and verify that the expected planning results have been generated.
7. How would you prepare materials and capacity for a new product introduction?
Ans:
Review launch demand, component requirements, supplier commitments, manufacturing capacity, and distribution needs. Identify long-lead components and possible constraints early. Coordinate with procurement, production, sales, and logistics teams to establish readiness milestones and monitor supply availability throughout the launch period.
8. How does cross-functional coordination improve customer order fulfilment?
Ans:
Purchasing, production, inventory, and logistics teams depend on accurate and timely information. Coordinating supplier receipts, manufacturing schedules, stock availability, and transport plans helps prevent conflicting decisions. Sharing updates promptly enables teams to address disruptions and maintain realistic customer delivery commitments.
9. What should be documented in an SAP SCM functional specification?
Ans:
Describe the business requirement, current process, desired outcome, affected transactions, and expected system behaviour. Include business rules, exception scenarios, reports, data requirements, and integration dependencies. Review the specification with stakeholders and define acceptance criteria to guide configuration, development, and testing.
10. How would you evaluate SAP SCM performance after implementation?
Ans:
Establish baseline measures and review operating results over a representative period after deployment. Monitor inventory levels, shortages, supplier delivery performance, order fulfilment, and planning accuracy. Consider demand and supply changes, collect user feedback, and identify further improvements when operational targets are not achieved.
