The task list template is designed to meet the needs of the people involved in the project.
Furthermore, for more complex events, each task may have multiple parts. Those sub-tasks could be listed and the person responsible for that overall task could keep track of the steps that are being completed and then presented to the project manager or whoever is directing the event.
The to do list template could also be used by students who have been assigned special projects to do. In this case, the project sheet can serve as an outline of what steps have to be taken to complete the project.
