The subsequent IT project selection for the IT portfolio is additionally influenced by political factors, various (partially unclear) standards, and questionable evaluation methods. There is a risk of misinvestment in IT projects that do not fit the company's strategy and accordingly lead to misallocation of resources. To solve this problem, this study will develop requirements for a decision support system that will enable a systematic, comprehensive, and transparent decision-making process for selecting suitable IT projects.enProject portfolio managementIT project evaluationproject assessmentsIT project selectiondecision support systemrequirementsrequirements templatesPARISPatterns for Requirements SpecificationRequirements for a Decision Support System for Managing Complexity of Multidimensional IT Project Assessments in the Context of IT Portfolio ManagementText/Conference Paper
