Most events have an overall flow which you should familiarize yourself with. It’s possible your event will have some changes, and most events will have a much more detailed internal schedule, so be sure to take a look at that as well!
Once you’ve created a preliminary Run of Show, you should have a good idea about your staffing needs. It’s important not to overwork your volunteers (or they won’t come back), so you should try to ensure no one works more than 12 hours during the event.
The easiest way to schedule volunteers is to create a Google Spreadsheet with the times on columns, and volunteer names in rows. Have volunteers highlight their desired shifts by colouring in the cells next to their name.
You should set a lock date for this schedule, and then add staff on-/off-shift events to your Run of Show. You can then send volunteers the relevant training in the CodeDay guide.
