Visualization of the Values of Requirements Attributes with Goal Models

Resumo

Attributes such as cost, risk, priority, and customer satisfaction are integral components of requirements specifications, helping with decision-making during the software development process. Moreover, requirements status and stability are relevant meta-information for requirements management. Even though goal modelling is a visual approach for requirements engineering that enables expressing and reasoning about goals, qualities, tasks and resources, existing approaches do not include the aforementioned attributes as part of the visualization of the models. This paper presents a set of strategies for visually representing requirements attributes over goal models, aiming at minimizing the cognitive effort required in their analysis. The proposal is supported by a tool that implements the visualization strategies here defined. Empirical evaluation of the effectiveness of the proposal, however, is expected to be carried out as future work.
