Entertainment is the primary product of many kinds of event, although not all events. A wedding is an event but the core product is the ceremony itself, of course weddings may include entertainment products also – typically from DJs (and Dad dancing!).
At entertainment centered events both Events Management and Entertainment Management are concerned with all three levels of product and this is where cross-over between the subjects exists. It would be as foolish for Event Managers not to be concerned with the management of entertainers at events, as it would be for Entertainment Managers not to be concerned with signage and seating for entertainment events. Getting all levels of product to match audience expectations and needs is part of the recipe for a successful entertainment event, after all it is no good having a stage crammed with world-class entertainers, if the audience are not comfortable, or couldn’t find the venue in the first place. The diagram below shows all three levels of product for a football match.
