Versioning, training, audit cadence
An SOP that does not have a version number is not an SOP. It is a draft someone forgot to date. The discipline around versioning, training, and audit is what separates SOPs that decay over 6 months from SOPs that evolve with the property.
Versioning
Every SOP has a major version (v1, v2, v3) and a minor version (v3.1, v3.2, v3.3). Major versions are rewrites — the procedure has changed substantively. Minor versions are clarifications or edge-case additions. Each version is dated, signed by the department head, and stored centrally.
When v3.2 is published, v3.1 is retired and removed from the front desk binder. Two versions of the same SOP in circulation is a guarantee that some staff will be running v3.1 procedure six months after v3.2 went live. The retirement step is non-negotiable.
Training
A new version triggers a training requirement. The training is short — 3-7 minutes per SOP — and happens at the next departmental shift huddle after the version goes live. Each staff member signs an acknowledgment that they have read and understood the new version. The acknowledgment goes into the central log.
A new hire receives a full SOP packet during their first week. The packet contains the current version of every relevant SOP, not historical versions. The hire signs an acknowledgment for each SOP within their first 14 days.
Audit cadence
Every SOP gets audited at least every 12 months. The audit asks three questions: (1) is the procedure still accurate (do we still do this the way the SOP describes), (2) are the edge cases still the right ones (or have we encountered new edge cases that should be added), (3) is anyone actually following the SOP (random observations of 5-8 instances over the audit period).
An SOP that fails any of the three audit checks gets a major version bump. An SOP that passes all three gets a minor version bump with the date and "no procedural change, audit passed."
What this prevents
The pattern this discipline prevents: an SOP written in 2023, never updated, that everyone has stopped following because the property has changed (new PMS, new room categories, new check-in flow). The SOP still sits in the binder. Compliance is reported as "yes we have an SOP for that" when in fact the SOP describes a procedure no longer in use. This is how brand audits and incident investigations get destroyed.
