This thesis examines how Project Management theory can help improving and streamlining processes in early-stage companies that struggle with the management of complex procedures. The study analyses a real case at an IT company providing a European-wide service, mapping out the company's existing organizational structure and identifying weaknesses and deficiencies in its processes. The first chapter focuses on the theory of Project Management, Organizational Project Management and PMO, while the second chapter goes on the company organizational description and maps in detail the OPM framework before any intervention. Finally, the third chapter presents the analysis of main problematics in turning inside the entire process, which correspond to identification of the strategy by the Board of Directors, the low accuracy during the evaluation phase and the reporting and monitoring issue.
