摘要：Goal modelling usually takes place during the early information systems development phase known as requirements engineering (RE). RE is a key factor for project success where a good tool support is necessary. Several goal-modelling tools exist and several approaches can be used to evaluate them. In this paper, we report on an experiment to evaluate two goal-modelling tools - KAOS/Objectiver and i*/OME. We use an RE-tool evaluation approach (R-TEA) in order to determine which of the tools is better at supporting the creation of goal models. It turns out that KAOS/Objectiver apparently offers better model creation support but the quality of the resulting models is more dependent on situational language characteristics such as the focus on early (vs late) requirements.
