A home football game needs the visiting team's travel party size and arrival window, the officiating crew and replay official, the broadcast window that sets kickoff, a law enforcement staffing plan, an ambulance on site, press box credentials, and the concessions load-in schedule. Almost none of it comes from people inside your department.
Teamworks coordinates the people who work for you — athletes, coaches, and staff, on your roster and behind your login. A home game also depends on the people who don't: the visiting team's travel party, the officiating crew, the broadcast truck, campus police, and the concessions vendor. None of them are going to take a seat in your staff system. That group is the one Homestand is built to reach, through a scoped link with no app and no account. It sits next to what you have rather than replacing it.
