This paper introduces an approach to multi-perspective requirements engineering (PREview) which has been designed for industrial use and discusses our practical experience in applying PREview. We have developed a flexible model of viewpoints and, using examples from an industrial application, show how this can be used to organise system requirements derived from radically different sources. We show how 'concerns', which are key business drivers of the requirements elicitation process, may be

We briefly describe the process of using PREview which has been designed to allow incremental requirements elicitation. Finally, we discuss some practical considerations which emerged when the approach was applied in industry.
