Confirm the "face validity" of the new cleaning process by demonstrating it with a couple of housekeeping staff members and a supervisor.

When testing changes that involve patients, it can be helpful to conduct an initial test using staff only. A simulation or practice session before going live is often a good way to uncover issues with high risk.
