The discipline of enterprise architecture advocates the use of models to support decision-making on enterprise-wide information system issues. In order to provide such support, enterprise architecture models should be amenable to analyses of various properties, as e.g. the availability, performance, interoperability, modifiability, and information security of the modeled enterprise information systems. These pages present a software tool for such analyses.
EAAT stands for Enterprise Architecture Analysis Tool and is a software system for modeling and analysis of enterprises and their information systems. The EAAT tool is inspired by graphical decision-theoretic methods, such as Bayesian networks and influence diagrams. EAAT is a versatile and user-friendly environment for modeling and analysis of enterprises and their information systems. The modules, developed at ICS at KTH in Sweden, are publicly available since September 2008.
