Extended abstract: requirements modeling within iterative, incremental processes

Requirements modeling is an established method for detecting defects in requirement specifications. Although many companies have successfully incorporated requirements modeling in their software processes, other companies face technology adoption problems: methods appear incompatible with processes and technologies in use, and with the attitudes of engineers. We approach this problem by adaptation of standard modeling know-how to existing practices and attitudes in certain companies. By a requirements modeling process that respects the constraints of iterative, incremental, use case driven development, and that uses a modeling language with a low learning barrier (for engineers), we hope to make companies that use the unified process amenable to requirements modeling.
