An IT-infrastructure capability model

The scale and complexity of todays IT-Infrastructures represent a challenge to understand the effects of modifications to these IT-Infrastructures or their components. This motivates the following research question: "How to evaluate high-level, global capability effects induced through low-level, local modifications to IT-Infrastructures?". Answering this question requires understanding of IT-Infrastructures in general and especially of their building blocks and of the complex interdependencies and ratios between capabilities, which have to be considered while planning modifications. After further illustrating the environment by providing an exemplary scenario, the question is described in detail. Preliminary results and the next steps to conduct on the way to answer the above mentioned research question are presented.
