1. How does SAP Integrated Business Planning support cross-functional planning?
Ans:
SAP Integrated Business Planning can connect demand planning, supply planning, inventory planning, and sales and operations planning activities. This helps teams evaluate demand and supply together, discuss constraints, compare scenarios, and develop plans that reflect service targets and business priorities.
2. How would you compare supply scenarios with different inventory and service outcomes?
Ans:
Compare the scenarios using inventory investment, expected shortages, service levels, supply costs, and operational feasibility. Review the assumptions behind each scenario and assess how the results affect customers and business targets. Recommend the option that best balances cost, availability, and risk.
3. What business decisions can be supported by a sales and operations planning cycle?
Ans:
A sales and operations planning cycle helps teams align expected demand with supply capabilities, inventory policies, and business objectives. It can support decisions about production volumes, purchasing needs, capacity constraints, and inventory targets. Cross-functional review helps resolve imbalances before they affect operational execution.
4. How would you identify the right inventory target for a critical component?
Ans:
Assess demand variability, supplier lead time, delivery reliability, replenishment frequency, and the business impact of a stockout. Review current inventory policies and service expectations, then evaluate suitable stock targets using the organisation's planning methods. Monitor actual shortage and excess-stock results to refine the target.
5. How can forecast error analysis improve future planning?
Ans:
Forecast error analysis compares predicted demand with actual demand to reveal the size and direction of differences. Reviewing these errors across products and time periods can identify persistent bias, seasonal effects, and unusual events. Planners can then refine assumptions and monitor whether forecast performance improves.
6. What are planning operators used for in SAP IBP?
Ans:
In SAP IBP, planning operators execute configured planning tasks such as calculations, data processing, or other planning-related activities, depending on the application and setup. They help standardise recurring planning work. Their parameters and execution results should be checked to ensure that the intended process completes correctly.
7. How would you evaluate the supply impact of a new product launch?
Ans:
Review the launch forecast, product availability dates, component requirements, supplier capacity, production resources, and distribution needs. Identify dependencies that could delay the launch and evaluate alternative supply scenarios. Coordinate with product, procurement, manufacturing, and logistics teams to align the launch plan with confirmed capabilities.
8. Why should procurement, manufacturing, and logistics teams share planning information?
Ans:
Shared planning information helps teams understand material requirements, production schedules, supplier commitments, and delivery constraints. Procurement can prepare incoming supplies, manufacturing can plan resource usage, and logistics can coordinate movement and dispatch. Better alignment reduces conflicting plans and improves response to supply disruptions.
9. How would you document a business requirement for a supply planning improvement?
Ans:
Describe the existing problem, the desired business outcome, affected materials or locations, planning inputs, and expected system behaviour. Record relevant business rules, exceptions, reporting needs, and integration dependencies. Review the requirement with stakeholders, define acceptance criteria, and use the approved document to guide configuration and testing.
10. How would you determine whether a supply chain process improvement has delivered lasting value?
Ans:
Define baseline measures before implementation and compare them with results over an appropriate period. Assess indicators such as inventory turnover, shortage frequency, supplier delivery performance, planning cycle time, and order fulfilment. Confirm that improvements remain consistent, consider changes in demand or operating conditions, and gather feedback from process users.
