This presentation discusses how software and systems development can benefit from a development approach that starts with requirements and uses them to drive the entire system lifecycle. To make this approach work it advocates the tight integration of requirement analysis with visualization modeling techniques, using the evolving UML 2.0 standard. The approach is rigorous, yet flexible, and when used with tools that support UML 2.0 can automate system verification and validation. Applying this approach throughout the system lifecycle can dramatically increase productivity and quality, which will reduce costs and time to market.
