Event Production and Logistics take a considerable amount of time to manage effectively.
So many wait until the last minute to actually plan their events and often these are fairly good sized ones. Three are a lot of moving parts to any event and not planning ahead can cause problems and higher costs.
By planning ahead and creating a production timeline helps you see what you may have neglected to consider. It also gives you time to talk with your event services vendor partners and massage the proposals submitted for the best outcome for your event.
Waiting till the last minute may force you to take what you get rather than what you want and need.
