The most appropriate strategy for the modernization project should be selected based on the companys external conditions. Therefore, IT decision-makers must know which factors influence the legacy system modernization strategy as well as the success of legacy modernization projects. In this Masters thesis, 15 possible factors influencing the legacy system modernization strategy and 14 possible factors influencing the success of such projects are derived from the literature and presented to IT decision-makers for them to weight using a survey. All the factors presented were considered to be relevant by at least a quarter of respondents. Further, respondents could define additional factors. The influences on strategy and projects were found to be versatile and multidimensional. Overall, the lists of factors discussed and weighted in this Masters thesis can support IT decision-makers make informed choices in the future.Author Ing.
