PREview

PREview (<u>Pr</u>ocess and <u>Re</u>quirements <u>View</u>points) is a requirements method which focuses on the early stage of Requirements Engineering: discovering and documenting requirements. PREview uses a Viewpoint-Oriented Approach to enable the conversion of top-level goals (“concerns”) into requirements and constraints Sawyer, P., Sommerville, I. and Viller, S. (1996).

Overview

PREview focuses on viewpoints for requirements engineering of computer-based systems but the viewpoint-concept is also used in various other areas of expertise. In communications, the ODP (Open Distributed Processing) Reference Model defines viewpoints from which a system can be specifiedFarooqui, K., Logrippo, L., and de Meer, J. (1995).
