Once you have chosen your event components, tasks, event coordinator, and committees, you will want to map out a backwards timeline. The timeline is a guide to make sure you include all the details and tasks to make the event successful.
Begin with the actual day of the event. This is week zero. Write down everything that will take place on the day of the event, including tasks, program, decorations etc.
Then, working backwards from week one, write down what needs to be done in the prior weeks to make your event occur as you have mapped out.
Make sure you map out the most important components first, and then add the less necessary components.
Also, having your committees map out their own backwards timeline for their specific component can be a very effective way to make sure they are aware of everything they are responsible for.
