Changes Nobody Assessed
A software patch, a new gasket material, a revised cleaning agent — each went live without asking whether requalification was needed. Cumulatively, the qualified system is gone.

Service · Periodic Review & Requalification
Validation isn't finished when the protocol is signed.
Equipment drifts. Software gets patched. Procedures change, people turn over, and suppliers reformulate. The validated state you documented last year describes a facility that no longer exists — unless something actively maintains it. We design periodic review programs and change-linked requalification that keep your qualification and validation evidence current, so an inspector never finds a gap between the paper and the plant.
WHY NOW
The validated state has a half-life.
Every change — planned or not — erodes it. Periodic review is how you prove the erosion never crossed the line.
Change controlThe trigger most plants underuse: every change should ask ‘does this affect the validated state?’ — and the answer should be documented, not assumed.
Scheduled reviewA risk-based re-verification of critical equipment, utilities, and systems — the routine that catches drift before an inspector does.
Living evidenceQualification isn't a binder on a shelf. We build review outputs that update the validation story instead of duplicating it.
WHERE IT BREAKS
The four ways the validated state quietly expires.
None of these announce themselves. All of them show up in inspections.
Reviews That Never Happen
The SOP requires annual review. Three years later, nobody has done one. The procedure exists; the practice doesn't.
Requalification Without a Trigger Map
Teams requalify everything on a fixed cycle — wasting effort on stable systems while high-change systems go unexamined. Effort follows the calendar instead of the risk.
Paper That Describes a Ghost
The IQ/OQ package is pristine and five years old. The equipment has been modified twice since. An inspector compares the two in about ninety seconds.
OUR METHOD
A maintenance program for your validation.
We build the program, run the first cycle with your team, and hand over routines your people can sustain.
Validated-State Baseline
We inventory qualified equipment, utilities, and systems, and record the current validated state — what was qualified, when, and under what configuration.
Review Schedule by Risk
Critical systems get frequent, deep review; stable low-risk systems get a lighter touch. Frequencies are justified by risk assessment, not by copying someone else's SOP.
Change-Control Linkage
We define which change categories trigger requalification, what level of re-testing each requires, and who decides — so the link between change and validation is procedural, not personal.
First Cycle & Handover
We execute the first periodic review alongside your team, close the gaps it finds, and leave behind the templates, checklists, and schedule your team runs going forward.
WHERE IT APPLIES
One method, five industries.
Cannabis is our home base — the method was built there first. The same evidence discipline serves each industry below, mapped to its own regulations.
Food & Beverage
Preventive controls, supplier verification, environmental monitoring, and traceability under 21 CFR Part 117 and FSMA.
Dietary Supplements
Component qualification, master manufacturing records, and laboratory controls under 21 CFR Part 111.
Cosmetics
Safety substantiation, GMP records, and adverse-event readiness under MoCRA.
Pet Food
Preventive controls for animal food, supplier programs, and sanitation under 21 CFR Part 507.
QUESTIONS
Periodic review, answered.
How often should periodic review happen?
It depends on risk: critical or high-change systems annually; stable utilities less often. We set frequencies by risk assessment, not by habit.
We have change control already. Isn't that enough?
Only if every change record actually assesses validation impact — most don't. We audit your change records against the validated state and fix the linkage where it's broken.
Does periodic review mean re-running full IQ/OQ/PQ?
Rarely. Most reviews are targeted verification: calibration status, change history, deviation trends, and focused re-testing where risk justifies it. Full requalification is reserved for significant change.
Can you run the program for us ongoing?
We run the first cycle and train your team to sustain it. If you need ongoing support — annual review execution, for example — we structure that as a defined engagement, not an open-ended retainer.
What about computerized systems?
Same principle, different checks: user access reviews, audit-trail review routines, patch and upgrade assessments, backup verification. Our CSV practice covers the system side.
