VALIDERING AV VERKTYGET "ENTERPRISE ARCHITECTURE ANALYSIS TOOL"

The Enterprise Architecture Analysis Tool, EAAT, is a software tool developed by the department of Industrial Information- and Control systems, ICS, at the Royal Institute of Technology, Stockholm, Sweden. EAAT is a modeling tool that combines Enterprise Architecture (EA) modeling with probabilistic relational modeling. Therefore EAAT makes it possible to design, describe and analyze the organizational structure, business processes, information systems and infrastructure within an enterprise. During this study EAAT has been validated in order to assess the usability of the tool and to provide suggestion of improvement. To reach conclusions EA models of IT systems out in the industry has been created in EAAT. A usability study has been performed in order to find weaknesses and strength in the tools user interface. The results of the study consist of a couple of scenarios of how the tool might be used by the industry. An important feature to improve is the possibility to easily find the weak parts of the system. The user interface should provide more feedback to the user. The modeling process could be improved by providing the user with suggestions on what to do next in order to reach a full and complete model
