Welcome to your interview.
The question is on your right: Design a Supply Chain Planning System. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are designing a supply chain planning system for a large retail and fulfillment operation. The system helps planners forecast demand, decide inventory levels, support S&OP, and plan capacity across warehouses and suppliers.
How would you model demand forecasting, inventory management, S&OP, and capacity planning in a supply chain planning system?
