The aim of this paper is to show all the activities that define the phases of the project, starting from the idea and preparation to its realization, on the example of the Carel Adriatic project. The first, theoretical part of the paper describes the five phases of the project and the role of project management in the management of all phases and project implementation. The project begins with an initiation phase that should have clearly defined goals and results. If they are not well defined, the risk increases that the project will not be completed in a certain time interval and the project is in the risk zone. The following is the planning phase in which all the activities needed to complete the project are defined, and team members are selected based on the activities. In the execution phase, we could see that all activities were done on time as a result of the previous planning phase. The project ends with a monitoring and management phase, followed by a project closure phase. In the second part of the paper, through practical examples of the project "Carel Adriatic", all phases of the project are processed and the activities that are primary for the successful completion and implementation of the project are listed.
