Many developers learn programming by focusing on functions, classes, frameworks, and algorithms. Early in our careers, success often means writing code that works and implementing features according to requirements. However, as software systems grow, problems rarely exist in isolation.
A change in one service affects another. A database bottleneck impacts user experience. A seemingly simple feature can trigger unexpected consequences throughout an entire platform. Teams discover that fixing one issue may create several new ones elsewhere.
Understanding these interactions requires more than coding skills it requires systems thinking, although often confused, systems thinking and system design are not the same thing.
System Design is about building systems.
Systems Thinking is about understanding systems.
