Part 1
Course reading
A planner balances customer service, inventory and capacity. In an interview, explain how you convert history, orders, promotions and market knowledge into a demand plan. Do not claim that a forecast is exact. Explain how you measure error, review exceptions and agree one practical plan with sales, production, procurement and finance.
Use a simple example: demand averages 1,000 units a month, confirmed orders are 700, usable stock is 250 and an open receipt of 300 arrives before the requirement date. Explain what else you would check before proposing the remaining supply. Mention lead time, safety stock, lot size, capacity and whether the open receipt is reliable.
Prepare two STAR stories: one about improving forecast accuracy or reducing a shortage, and one about resolving disagreement in S&OP. Finish with the measured result, such as fewer emergency orders, lower excess stock or better service. If you are a fresher, use a worked classroom example and clearly label it as practice.
