Event managers plan, organize, and supervise events, such as business conferences, weddings, and festivals. They handle all the arrangements required to make the event run smoothly. Event managers determine what the client needs and expects; then they coordinate the preparations leading up to the event, including booking venues, scheduling transportation, and selecting the food and decorations. They may even need to hire staff for the event. Event managers may need to employ reliable waiters, entertaining DJs, and talented photographers. Event managers monitor payments and budget, and ensure the event meets all required safety regulations. Large-scale corporate gatherings require management, so the event manager often delegates and oversees planning tasks to focus on operating on-site the night of the occasion.
