Put four people around a table.
Invite a front-line observer, a supervisor, someone responsible for protective decisions, and whoever communicates with law enforcement. If your setting includes children or people needing assistance, include someone who knows those arrangements. Fifteen minutes is enough to expose a handoff gap.
Use a simple observation.
“A staff member reports that a visitor tried a restricted door twice after being directed to the front desk. The visitor has left. No threat was spoken.” Ask who receives the report, what facts are missing, when police should be called, what footage is preserved, and what staff should do if the visitor returns. Then add one change: a specific threat is heard. Ask which decisions change immediately.
Finish with one correction.
Write down who owns the reporting contact list, when it will be updated, and how staff will practice using it. Do not turn the exercise into an investigation of a fictional suspect. The point is to make the first decision and the handoff to responders reliable.
