Why learn System Design?

Many people struggle with System Design not because they lack effort, but because three foundations have not been made explicit. They may build quickly, but the work still drifts, becomes fragile, or is difficult for others to follow.

You already use some of this knowledge whenever you make a product decision, design a feature, or discuss a solution. The course makes that implicit knowledge visible; the parts you do not yet know are learnable skills.

These three foundations become six common blind spots in practice. The next six lessons make each one visible, then give you a more deliberate way to work.
