Rambling thoughts of an architect

Quoted from Martin Fowler:

Complexity

• Making something easy to change makes the overall system a little more complex, and making everything easy to change makes the entire system very complex. Complexity is what makes a system hard to change.

Limitations

• Software is not limited by physics, like buildings are. It is limited by imagination, by design, by organization. In short, it is limited by properties of people, not by properties of the world. “We have met the enemy, and he is us.”
