What you’ll learn

  1. From need to productExplain how procurement, production, and warehousing connect inputs to finished goods.A supply chain joins sourcing, transformation, and storage rather than treating the factory as the whole story.
  2. Moving, storing, and knowingDescribe how transport, ports, warehouses, and information systems coordinate physical flow.Goods change location through linked modes and handoffs, while records and signals help each stage decide what to do next.
  3. Balancing demand and resilienceExplain inventory trade-offs, the bullwhip effect, and the choices that make a chain more resilient.Inventory cushions uncertainty but costs money, and local guesses can amplify upstream. Resilience comes from deliberate alternatives and visibility.

Questions this course answers

Which statement best describes a supply chain?

A supply chain links sourcing, operations, logistics, resources, and information from inputs to the customer.

Put these broad stages in a typical product journey in order.

Planning and sourcing precede production; logistics then positions finished goods for the customer.

Match each supply-chain activity to its main job.

These functions are distinct but interdependent; the chain performs well only when their handoffs work.

Why can a small change in customer demand create a larger change in factory orders?

Each stage may update its forecast, add safety stock, and order in batches while waiting through a lead time, amplifying the signal as it moves upstream.
