Representation, Assessment and Improvement of Information Systems Architecture
Abstract
This paper presents an alignment model for IS-architecture work that integrates previously separate lines of work. The model explains what it means to group IS-architecture elements into IS-architecture areas and thereby offers a systematic way to generate alternative future IS-architecture solutions. This aids IS-architecture work in several ways and offers possibilities for automated tool support. A major benefit is that the grouping principles used in the alignment model can act as high-level principles for IS-architecture evolution in the long term. The alignment model is embedded in a comprehensive methodology that also offers a representation framework, a position, a method and a modelling tool for IS-architecture work. The methodology results from several years of case and theory studies, tool development, industrial projects and consulting.
