(1) The History of RUP

In 1997, Rational defined six best practices for modern software engineering,

• Develop iteratively, focusing on risk
• Manage requirements
• Employ a component-based architecture
• Model software visually
• Continuously verify quality
• Control changes

These six practices, that we just mentioned were the starting point…
