- Multiple agent-oriented methodologies has been introduced in recent years, although only partial evaluations of these have been offered. As a result, it is difficult to select a methodology for a specific project. Additionally, there are no means for determining what the advantages and drawbacks of each methodology are. To resolve these problems, we devise a framework for evalu- ating and comparing agent-oriented methodologies. This framework focuses on four major aspects of a methodology: concepts and properties, notations and modelling techniques, process and pragmatics. We demonstrate the usage of the suggested framework by evaluating the GAIA methodology. This evaluation identifies the strengths and the weaknesses of GAIA, thus exemplifying the ca- pabilities of our framework.
