This thesis paper analyzes the critical role of project management offices (PMOs) and data visualization techniques in improving the operational effectiveness of first-mile warehouse operations. The research begins with a review of current literature on PMO functionality and the strategic use of data visualization and dashboards, laying a theoretical foundation that emphasizes the importance of these tools in managing complex logistics projects. The research then moves to a practical examination in the context of Amazon's European Global Engineering Services PMO, focusing on my direct contributions as a Project Manager and Business Analyst. As Project Manager, my main project was to significantly expand the scope of our team's projects by developing from scratch a new reporting framework for External Fulfilment projects.
