The team therefore treated the queue as a signal to inspect the handoff between arrival and repair, rather than as evidence that the event simply needed to become larger.\n\nThe proposed response was to make that handoff teachable. A short safety checklist would give every volunteer the same opening questions, while a daily review would capture cases the checklist missed. This is a hypothesis about the service, not a measured result. Cedar should test whether first-time volunteers can apply the checklist, then observe whether waiting changes.
