Systemic Risk in IT Portfolios - An Integrated Quantification Approach~1 Completed Research Paper

摘要

Recent trends in digitalization, combined with continuous innovation pressure, have led to an increasing number of IT projects that are often accomplished within huge IT project portfolios. Although numerous IT project and portfolio evaluation and planning approaches have been developed and applied in companies all over the world, approximately 25% of IT projects still fail, which may result in a global value destruction of approximately 900 billion USD. One main reason for the numerous failures is the lack of transparency concerning dependencies within IT portfolios. This paper draws on graph theory to present a rigorous assessment of systemic risk that is based on different types of direct and indirect dependencies within IT portfolios. Based on this assessment, an integrated, novel, and quantitative approach to IT portfolio evaluation is presented that strives to mitigate IT project failures as it helps decision makers to evaluate their IT portfolios more adequately.
