This project management case study analyzes the planning and execution of an Olympic-style indoor sporting event, the HEI Games. The report begins with a Project Initiation Document (PID) outlining the project's objectives, scope, stakeholders, and key milestones. It then details stakeholder analysis, identifying the influence and interest levels of various parties like sponsors, project managers, and customers. The study provides a full breakdown of event activities, presented in a Gantt chart and Work Breakdown Structure (WBS). Risk management is addressed through a comprehensive risk register, detailing potential threats such as technical faults, low customer footfall, and terror attacks, alongside mitigation strategies. The report also explores project management theories, including closed-loop managerial processes like executing, controlling, and planning, and presents a detailed project budget, including financial programs, cost breakdowns, and funding sources. The case study concludes with a discussion on different project management methodologies to organize the HEI Games.
