Model based requirements engineering for embedded software

Summary form only given. Software and systems development within the embedded area is dominated by model based design techniques. These techniques are commonly aligned to standard. modeling languages such as UML. Along with software and systems design techniques the concern of requirements management methodologies has been continuously increasing, with the aim of improving the overall development process. As a combination of both model based design techniques and requirements management methodologies, a new kind of requirements engineering methodology has been established. However, due to the complexity of this methodology and the high degree of informal aspects a unique and integrated methodology for requirements engineering is still needed. This presentation gives a survey of existing requirements classifications and motivates the use of model based requirements classification techniques. The transition of informal requirements to first models is illustrated.
