Why are global supply chains still so vulnerable to disruption?

Global supply chains are like a long train that moves things from one place to another, but it's still easy for something to go wrong.

Imagine you and your friend are building a big tower with blocks. You both have different sets of blocks, and you pass them back and forth so the tower gets taller. But if one of you drops all their blocks or can’t find theirs, the whole tower might fall, even though it looked like everything was going fine.

Supply chains work in a similar way. Companies around the world send parts to each other, kind of like passing blocks. If something happens in one place, like a factory stops working or a ship is delayed, it can cause problems all the way down the line.

Think of supply chains as a game of telephone. One person starts a message, and it gets passed along from one to another. But if someone misunderstands the message or can’t pass it on, the final message might be totally different, just like how things can get messed up in a long chain of companies.

Sometimes people don’t plan for these little problems, so when they happen, everything gets stuck, like a traffic jam on a busy road. That’s why supply chains are still so vulnerable to disruption!
