Abstract

In critical and robust systems, requirements modeling and analysis is an essential step, called requirements engineering, in the process of system development, which stems from the non-ambiguous identification of endusers and stakeholders needs and goals. Despite the wide application of requirements engineering methodologies, such as KAOS, i⋆/Tropos, often this step is marred by either the lack of robustness or the lack of usability on part of the analysts. In this paper, we present a 3-dimensional model of requirements, called the Requirements Cube, that is clear, usable and can be manipulated using general matrix algebra. Our model stands on the three main components of requirements; goals, resources and infrastructure, and does not present any complex concepts that may render it unusable. We consider the semantics of the Cube in three different value domains: 2- and 3-valued logic values and probabilistic values. Finally, we demonstrate how this model can be applied to healthcare monitoring scenarios.
