Look at the canvas below. Six shapes. Different colors, different forms. Click on them. Go ahead.
Nothing happens. Because a pile of parts is not a system. A system needs three things: components (the parts), connections (relationships between them), and purpose (what they do together that none can do alone).
Click the shapes. Try to make something happen.
What you just saw
Before connection, you had components. After connection, you had a system. The shapes didn't change. What changed was the relationships between them and the shared behavior that emerged. That's the difference between a pile of parts and a system.
Every system you'll encounter in this course, from a water tank to a national economy, follows this same rule. Parts alone do nothing. Parts plus connections plus purpose create behavior.
