Would You Like Better Visualization for Requirements Prioritization and Release Planning?

Abstract

On the one hand, requirements prioritization is a key requirements engineering activity that lacks proper visualization support. On the other hand, goal modelling is a visual approach for requirements engineering that enables expressing and reasoning about alternative solutions that best match the stakeholder needs, both for the early requirements and the late requirements phase. This paper proposes a set of strategies for visually representing prioritization and release planning information using goal-based models, aiming at minimizing the cognitive effort required in prioritization analysis. The proposal is supported by a tool that implements the visualization strategies here defined.
