System Modelling for Requirements Engineering
This chapter introduces system modelling as an important complement to requirements management. System modelling supports the analysis and design process by introducing a degree of formality into the way systems are defined. During system development it is often the case that pictures are used to help visualize some aspects of the development. Modelling provides a way of formalising these representations, through diagrams, by not only defining a standard syntax, but also providing a medium for understanding and communicating the ideas associated with system development.
