In the world of large-scale events, the margin for error is minimal. The consequences of arrangement failures can be significant, leading to public displeasure, criticisms, and financial losses. A prime example of such a scenario unfolded during the Waterbomb Hong Kong event, where poor organization and logistical mishaps left attendees frustrated, underscoring the dire need for efficient planning and management. This incident shines a spotlight on the indispensable role of advanced business software, particularly Enterprise Resource Planning (ERP) systems, in orchestrating large events successfully.
