How supply chains work

Seven lessons on how products get from raw materials to your hands: suppliers and tiers, the jobs every supply chain does, lead times, push and pull, the bullwhip effect, service against cost, risk and resilience, and sustainability. No maths beyond a little arithmetic.

How it works

Each lesson is a short read with examples, then a few practice questions. Some ask you to type an answer (a number, an address, what a piece of code prints), some have you pick one, and some have you tap steps or lines into the right order. You can try again as often as you like; after two misses there’s a button to show the answer.

What do I need to know first?

Nothing. It starts from zero.
