Validation

Leaders in Proving the Systems
Your Compliance Runs On

The Invisible Infrastructure

Your Quality System Is Software Now. Prove It Works.

Batch release, training records, deviation workflows, lab results, electronic signatures: nearly every GxP decision your company makes now travels through software. Computer system validation is the discipline of proving those systems do what your procedures claim, protect the data they hold, and fail in ways you would notice. Done in the old style it buries teams in screenshots; done in the modern, risk-based style it concentrates rigor exactly where a system failure could reach product quality or data integrity. We practice the modern style.

The batch record is a database row now. Validation is how you earn the right to trust it.

The Shape of the Work

Specify Down One Side. Prove Up the Other.

The V-model endures because it enforces one honest rule: you can only verify against what you specified. Each requirement written on the way down is matched by evidence on the way up — and the dashed lines across the V are where auditors look for daylight.

Specify

User Requirements (URS)

What the business and the regulations need the system to do — testable, numbered, owned.

Specify

Functional Specification

How the system will meet each requirement, including the configuration you actually deploy.

Specify

Design & Configuration

The technical detail: interfaces, security model, audit trail settings, data flows.

Prove

PQ / UAT

The system performs in the real workflow, with real users, against the URS.

Prove

OQ / Functional Testing

Each specified function challenged, including the unhappy paths and the audit trail.

Prove

IQ / Installation Verification

The right system, the right version, the right environment, verifiably in place.

The turn of the V

Build or Configure

Where GAMP category decides everything: a configured SaaS product and custom code deserve completely different depth.

Testing is thinking

A test script that cannot fail is documentation, not assurance.

The Modern Doctrine

From CSV to CSA: Less Paper, More Assurance.

FDA’s Computer Software Assurance guidance made official what good practitioners already knew: the goal is confidence in the system, not weight in the binder. The shift rewards critical thinking — and exposes programs that were only ever producing paper.

The Old Reflex (CSV as paperwork)
The Modern Standard (CSA)
Validate every system to the same exhaustive template, because that is what the SOP says.
Risk first: depth follows what the system can do to patient safety, product quality, and data integrity.
Screenshot every click; spend 80% of the effort formatting evidence nobody reads.
Test more, document leaner: unscripted and exploratory testing where it finds more, records fit for an auditor.
Re-prove what the vendor already proved, badly, from outside the code.
Leverage the vendor: assess their lifecycle honestly, then test your configuration and your use, not their kernel.
Validation as a one-time event that ends at go-live and quietly rots.
Assured operation: change management, periodic review, and audit-trail review keep the state proven.

Testing focused where the risk is

A risk-based CSA approach: rigor concentrated on what affects product quality and data integrity, not every screen.

Rolling out an eQMS or LIMS, or staring at a validation backlog that grows faster than it closes?

Talk to an Expert
The Regulated Estate

The Systems That Count, and What Each One Demands.

A validation program is an inventory before it is anything else: every GxP system identified, categorized, and assured at a depth that matches its blast radius.

Quality

eQMS

Documents, training, CAPA, change control. The system of record for your compliance itself — with Part 11 signatures throughout.

Laboratory

LIMS & CDS

Sample lifecycles and chromatography data: the highest data-integrity stakes in the building, and the first place inspectors look.

Manufacturing

MES & Automation

Electronic batch records, recipe management, and the PLC/SCADA layer beneath them, validated against the process, not just the code.

Clinical

EDC & eTMF

Trial data capture and the trial master file: GCP obligations expressed as software, audited by sponsors and agencies alike.

Enterprise

ERP & Supply

Inventory status, genealogy, and release interactions — GxP-relevant modules carved out and assured inside a much larger system.

The Sleeper

Spreadsheets & Small Apps

The macro that calculates potency and the database someone built in a weekend. Small systems, real decisions, routinely uncontrolled.

Every instrument with a hard drive is part of your validation estate, whether it is on the list or not.

What We Are Hired to Prevent

Where Validation Programs Actually Fail.

Almost never in the protocol template. The failures are structural, and every one of them is visible in advance to someone who has run these programs before.

One depth fits all

The cloud CRM and the sterility-adjacent MES validated with identical rigor, so neither gets the attention its risk deserves.

Evidence without assurance

Thousands of screenshots proving the happy path works, and not one challenge to the alarm, the interface, or the audit trail.

The vendor halo

“It’s validated by the vendor” — a sentence that has never once been true. Their testing covers their code, not your configuration or your use.

Go-live amnesia

A pristine validation package for version 4.2, and three years of updates since, none assessed. The system in production is no longer the one that was proven.

The unowned periodic review

Audit trails nobody reads, accounts nobody deactivates, and a review calendar that exists only in the SOP.

Where validated systems quietly fail

Audit trails nobody reads, accounts nobody deactivates, a review calendar that lives only in the SOP. We find them first.

Who You Work With

Validation Leads Who Speak Both IT and Inspection.

CSV sits between two worlds that rarely understand each other. Your leads have run validation programs inside quality organizations, managed the IT projects being validated, and defended both in front of investigators.

GAMP 5 Native

Second-edition thinking throughout: categories, critical thinking, and supplier leverage applied as designed, not recited.

CSA in Practice

We have converted legacy CSV programs to assurance-based models that regulators accepted and teams could sustain.

Cloud-Realistic

SaaS release cycles you cannot pause, validated with continuous-assurance approaches that keep pace.

Inspection-Tested

Our packages have been pulled in PAIs and surveillance inspections, and they held.

Where to Go Next

The Work Validation Connects To.

System assurance is one layer of a digital quality estate. These are the services most often engaged alongside it.
