The framework is divided into 3 main areas, which are:

• Metrics - all the metrics defined and used in this research work, for easy access and reference.


• Tools - the tools for the creation of i* 1.0 and iStar 2.0 models, and the automated collection of product metrics about the created models.


• Experiments - all the experiments performed in this research work, for the evaluation of i* and use cases. They can be used for conducting independent replications.

Important Please note that the framework is optimised for a 22 inch, full HD monitor, with a 1920x1080 resolution. It is also optimised for Google Chrome, in full screen mode (F11 or Fn+F11). All the elements on the screen needed to be comfortably readable by our participants, hence the optimisation for those sizes. However, the experiments may not appear correctly on screens with a different size.

Explore away, and have fun!

Thank you,
