A requirements engineering environment within a tightly integrated SDE

This paper describes the outside functionality of an RE environment within an integrated software development environment. Furthermore, an integrator tool for the transition to software system architecture modelling is presented. The tools discussed are editors, analysers, executors, monitors, and integration tools of different characteristics for horizontal integration (within RE) and vertical integration (to architecture modelling). All tools are tightly integrated and work incrementally, therefore allowing different forms of construction and modification processes and giving substantial support.
