How to know whether a system is well designed or not?

This is part of system design process. Which will be covered later in other course.

But in general:

• Operational pattern: Well designed system solve multiple problem sets at once without have to introduce new component.
• Minimal set of changes to deal with uncertainty.
• "Almost symmetric"
  • Look at how God design human and animal body
• Self-reinforcement. Once a system is built and stable, it rarely change
  • Can be a disadvantage or advantage.
  • Component within the system even fight to protect the system from radical change (true in biology, business, politics).
