“Almost 2000 years ago, the Roman architect Vitruvius recorded what makes a design good: durability (firmitas), utility (utilitas), and charm (venustas). These quality requirements still hold, for buildings as well as software systems. A well-designed system is easy to implement, is understandable and reliable, and allows for smooth evolution. Badly-designed systems may work at first, but they are hard to maintain, difficult to test, and unreliable.”

Understanding

“Present-day applications are rather different in many respects. Present-day programs are often very large and are being developed by teams that collaborate over periods spanning several years. These teams may be scattered across the globe. The programmers are not the future users of the system they develop and they have no expert knowledge of the application area in question. The problems that are being tackled increasingly concern everyday life: automatic bank tellers, airline reservation, salary administration, electronic commerce, automotive systems, etc. Putting a man on the moon was not conceivable without computers.”
