Intro supply chain

The interesting thing about supply chain management is that every product has a story, and every product is part of multiple supply chains.
You need to have supply chains to overcome the tyranny of time and space.
The same decisions are being made by the people managing those supply chains in each one of these products.
Now the values and the outcomes might differ, but they're all making the decisions of
where can I source from?
How much inventory do I hold?
How do I forecast my demand?
Where do I stock my inventory?
How do I move my product from source to final consumption?
