This thesis is divided into a theoretical and a practical part, where business case itself influenced the profiling of the presentation in the theoretical part. It is about managing and leading the IT infrastructure implementation project in a taken-over company in a country on another continent. That company will be completely reorganized technologically and administratively in order to extend production capacity of whole multinational corporation. IT infrastructure must support the way production processes are managed, but also all other business systems used by the company, as well as establishing communication link with the central office on the one hand (internal communication links), and with cloud technology and the open internet on the other hand (external communication links). Theses topic presents IT infrastructure implementation with all the peculiarities and risks in that area, the most specific of which is the rapid development of information technology, which can result in significant changes to the plan in the middle of the project execution. The case is presented as clearly as possible, with the note that all sizes and values have been changed by a common coefficient, but all relationships are completely preserved and realistic. In the segment of this research, the most important result is to show known-how when managing IT infrastructure projects. Knowing how to correctly apply theoretical knowledge in the practice is a fundamental of any engineering approach. However, the basic approach to all stakeholders is an assertive way of leadership, no matter how much it is requested, especially in some stressful and even provocative situations.
