How often should SOPs be reviewed?
Review SOPs on a risk-based schedule and whenever a material event changes the work; there is no universal review interval for every organization. See a worked QueryChart workflow and the checks needed to use it.
Review SOPs on a risk-based schedule and whenever a material event changes the work; there is no universal review interval for every organization.
The short version
- Set risk-based intervals: Consider harm, regulatory duties, process volatility and the cost of stale instructions.
- Add event triggers: Review after relevant system changes, incidents, deviations, audit findings or new requirements.
- Record every outcome: Reaffirm unchanged content with a new date, or route a revision or retirement through control.
How often should SOPs be reviewed in practice
A fixed annual date may be too slow for safety-critical procedures and pointless for a stable low-risk task. Systems, regulations, incidents, deviations and audit findings should trigger review immediately when they affect the instruction.
Set each SOP’s interval by risk, change frequency and external requirements. Assign an owner and next date, monitor triggers between scheduled reviews, and record a reaffirm, revision or retirement decision every time.
Find the SOP review trigger
Use the controlled SOP example to compare scheduled review with changes in the work that call for an earlier check.
Set risk-based intervals
The SOP is published with a scheduled next review date and named owner.
Add event triggers
Either the interval or a process change triggers reassessment of the live instruction.
Record every outcome
The still-current decision records reaffirmation; otherwise a revision path begins.

Mistakes to avoid
Treating the due date as the only trigger
A safety or system change can make an SOP wrong months before its scheduled review.

Frequently asked questions
Is annual review always required?
No universal annual rule applies; check your specific regulator, standard and organizational risk policy.
Does a trigger reset the interval?
Record the event review outcome and set the next date using your policy, rather than resetting silently.
Can a review close with no change?
Yes. Retain who reviewed, what they checked, the outcome and next due date.
