Planned, performed, verified
Those three words describe most of what is being tested. Planned means a schedule exists that someone unfamiliar could follow, with areas, tasks, methods and frequencies. Performed means there is a contemporaneous record rather than an assurance. Verified means somebody checks the result against the schedule and records what they found, including when it fell short.
The third is the one most practices lack. Cleaning is checked informally all the time, by whoever notices something, but informal checking leaves no evidence and cannot be described in a way an assessor can accept. A short documented supervisor check, even monthly, converts an existing habit into evidence at almost no additional effort. Practices that already walk the rooms informally are usually one short written note away from having the evidence they need.
