Zones and times rather than a task list
A general task list falls apart under time pressure because everything is nominally due at once. Splitting the venue into zones, each with its own completion time and its own crew allocation, gives the operation a sequence. It also makes the constraint visible: if three zones cannot be completed in the window, that is known during planning rather than discovered at handback.
The zone approach also handles partial completion honestly. When an event runs late or a zone is unavailable, the record shows which zones were completed on time and which were compressed, rather than presenting the whole turnaround as either done or not. That distinction matters when a venue is reviewing whether the window it allows is realistic. A venue that keeps those figures across a season can tell an incoming client what a turnaround actually requires rather than quoting from an assumption.
