Non-Functional Requirements and UML Stereotypes

Abstract

In Nuseibeh and Easterbrook (2000), an overview of the field of software and systems requirements engineering is presented. Therein is highlighted some key open-research issues for the future of the Requirements Engineering (RE). Some of the major challenges mentioned there, are related with the necessity of richer models for capturing and analyzing non-functional requirements. This paper draws some possible extensions of Unified Modeling Language (UML) (Booch, G., Jacobson, I. and Rumbaugh, J., 1998) in order to include non-functional requirements.
