Description: The i* framework (Yu, 1995) offers a graphical notation for modeling and analyzing socio-technical systems, particularly during early stage requirements engineering for software systems. A number of software tools exist to support i* modeling. Nevertheless, there is a strong need for better visual support in i* modeling. This study aimed to identify areas for improvement and to develop prototypes to address these areas. A review of existing i* tools and observation of users revealed that current tools provide inadequate support for maintaining an overall view of a model, filtering extraneous data and extracting sub-collections of the model data.Prototypes were then developed based on these needs, and an evaluation by users of i* was carried out to test the validity of the concepts and requirements included in the prototypes. User feedback suggested these prototypes would be useful when using software for i* modelling and offered suggestions for further improvements.
