This thesis deals with Risk Management within large projects. It is still a hot topic, because risk is an inherent part of any project and significantly affects its outcome. That is why it is paied more and more attention to Project Risk Management. This thesis is written in collaboration with a renowned multinational IT company delivering these large projects. One of the project factors is uniqueness. Conditions in the world are rapidly changing and companies are trying to gain a competitive advantage in their own IT. Uniqueness is obviously very important factor of IT innovation and that is the reason, why many companies implement their changes as a project. These projects must be directed to a succesfull outcome, therefore many methodologies was created to manage it. Current project are under greater pressure on the duration and cost of supply while maintaining high quality, which in practice means that to deliver successful projects is becoming increasingly difficult. Therefore, there should be greater emphasis on risk management, so an event that may threaten the success of the project. It is needed to learn and look for better and more efficient ways of Risk Management. The main scope of this thesis is to compare two project management methodologies (Prince 2 and RUP -- Rational Unified Process) with internal methodology of chosen IT company from the perspective of risk management and then to compare the project practices with the methodologies, to find any anomalies or errors and provide suggestions for improvement.
