: Models from methods like Contextual Design (CD) are a sound basis for requirements engineering. But current software engineering processes are not prepared to use such models. Together with tight schedule and budget project teams settle for the minimal work needed, which is writing use cases in case of the Rational Unified Process (RUP). HCI practitioners more and more need HCI methods effectively integrated into software engineering processes. As an example, integrating CD in RUP is outlined here.
