This article explains what FDA actually requires for QMS software validation, how the Computer Software Assurance (CSA) framework changed the traditional approach, and what pre-validated platforms genuinely deliver versus what they do not.

Why FDA requires QMS software validation

FDA’s position on software validation in regulated environments stems from 21 CFR Part 820.70(i), which requires that when computers or automated data processing systems are used in production or quality systems, those systems must be validated. The 2024 QMSR update preserved this requirement under 21 CFR Part 820.70 and incorporated language aligned with ISO 13485:2016 Section 4.1.6.

The logic is straightforward: if your quality system relies on a software platform to control documents, manage CAPAs, record batch data, or route approvals, then errors in that software can produce incorrect records or allow non-conformances to go undetected. Validation is how you demonstrate the system does what you say it does, consistently.

This applies to commercial off-the-shelf (COTS) software as much as to custom-built systems. Buying a QMS from a vendor does not transfer the validation obligation to that vendor. Your company remains responsible for demonstrating the software operates correctly in your specific environment and for your specific use cases.

The shift from CSV to CSA: what changed and what stayed the same

Traditional Computer Software Validation (CSV) under the GAMP 5 framework required extensive documentation: User Requirements Specifications (URS), Functional Requirements Specifications (FRS), Design Specifications, and detailed test scripts for Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ). For a mid-market QMS implementation, this documentation effort could run 6 to 18 months and cost hundreds of thousands of dollars before a single user logged in to do real work.

In 2022, FDA published its Computer Software Assurance (CSA) guidance, which fundamentally reframed the approach. The CSA guidance moved away from documentation volume as a proxy for validation rigor. FDA’s stated concern was that companies were generating enormous amounts of paper that did not actually prevent software failures — teams were spending more effort writing test scripts than thinking critically about risk.

Under CSA, the emphasis shifted to:

• Risk-based testing — focus testing effort where software failures would have the greatest patient or product safety impact
• Leveraging vendor testing — formally using vendor test documentation as part of your validation package rather than re-executing every test yourself
• Confidence-based assurance — matching the depth of your validation activities to the criticality and intended use of the software function

What stayed the same: you still need documented evidence that the software works as intended. The URS still matters. You still need to execute testing for your specific use cases. The IQ, OQ, and PQ concepts did not disappear — they became more selective, not eliminated.

What FDA validation documentation must include

Regardless of whether you follow GAMP 5 or the newer CSA framework, a complete QMS software validation package for FDA purposes typically includes:

Validation Plan

A document that defines scope, roles, responsibilities, testing approach, risk assessment, and acceptance criteria for the validation effort. This is the governing document that ties everything else together.

User Requirements Specification (URS)

A documented list of what your organization needs the software to do. The URS is written before any testing and forms the basis for all subsequent verification activities. Every requirement in the URS must be traceable to a test.

Risk Assessment

Under CSA, this is more important than ever. Risk assessment determines which functions require intensive testing, which can rely on vendor documentation, and which carry low enough risk to be addressed through other means. Functions that directly affect product quality records, electronic signatures, or audit trail integrity carry the highest risk and require the most rigorous testing.

Installation Qualification (IQ)

Evidence that the software was installed correctly in the target environment. For cloud-based SaaS QMS platforms, this typically covers account provisioning, tenant configuration, and confirmation that the correct version is running.

Operational Qualification (OQ)

Testing that confirms the software functions according to its specifications across the range of expected operating conditions. This is where most test execution occurs — document routing, approval workflows, form logic, access controls, and notification triggers.

Performance Qualification (PQ)

Testing conducted in the actual production environment with real users performing real tasks. PQ demonstrates that the validated system performs reliably under actual operational conditions, not just in a test environment.

Validation Summary Report

A document that summarizes test results, records any deviations or anomalies encountered, confirms that acceptance criteria were met, and formally approves the system for production use.

Traceability Matrix

A matrix that links every user requirement to the test(s) that verify it. During an FDA audit, inspectors will look for this to confirm your testing covered the scope you committed to in the URS.

What “pre-validated” actually means

Many QMS vendors market their platforms as “pre-validated” or “validation-ready.” These terms mean different things depending on the vendor, so understanding exactly what a vendor provides is essential before you rely on their validation package in your submission.

Genuine pre-validation typically includes:

• Vendor-executed IQ/OQ documentation — the vendor has tested their own system against documented requirements and provides that evidence for your review
• Vendor test scripts and results — executable test scripts and actual test results you can include in your validation package, reducing the re-execution burden on your team
• Validation package per platform version — documentation updated with every platform release, so your change control process for upgrades is supported
• 21 CFR Part 11 compliance documentation — evidence that electronic signature and audit trail features meet the requirements

What pre-validation does not eliminate: your PQ. Because PQ tests the system in your specific operational environment with your specific processes, workflows, and user population, no vendor can pre-execute it on your behalf. Your quality team still needs to design and execute PQ test cases that reflect how your organization actually uses the system.

Pre-validation also does not eliminate your URS. The URS is your document — it defines what you need, not what the vendor built. You cannot replace your URS with the vendor’s own specification.

How cloud-based QMS platforms reduce validation burden

Traditional on-premise QMS software created a persistent validation problem: every software update required a new validation cycle. In practice, this meant many quality teams ran on outdated software versions for months or years, accumulating technical debt and compliance risk to avoid the cost of re-validation.

Cloud-based SaaS QMS platforms changed this model in several ways:

Vendor-managed infrastructure

Cloud platforms run on vendor-managed infrastructure (typically AWS or Azure), which removes infrastructure IQ from your scope. You are not responsible for validating servers, operating systems, or database configurations — the vendor handles that and provides the documentation.

Configuration management environments

The best platforms allow you to maintain separate development, QA, and production environments, so configuration changes can be validated before they reach production. This supports the change control process required by both FDA QMSR and ISO 13485 without requiring manual migration work.

Validated update releases

Leading QMS platforms provide a validation package with every platform update, tested against documented specifications before release. This means your update change control process can leverage vendor documentation and focus your effort on regression testing for your specific use cases, rather than re-executing the full test suite.

Change control for validated QMS software

Validation is not a one-time event. Any change to a validated system — including configuration changes, new module activation, user permission changes, and software upgrades — must go through a documented change control process to determine whether re-validation is required.

Under the CSA framework, change control decisions are risk-based. A change that affects an audit trail, electronic signature, or critical quality record workflow requires documented impact assessment and likely requires re-testing. A change that modifies a low-risk notification template or report format may require only a brief documented review without re-execution of test scripts.

Your Process Change Notification procedure should explicitly address software changes as a change type, with defined criteria for when re-validation testing is required.

Common FDA observations related to QMS software validation

During FDA inspections of quality systems, software validation deficiencies appear regularly in FDA Form 483 observations. The most common include:

• No validation plan documented before testing began
• Test scripts executed without documented approval
• Deviations encountered during testing not formally documented or dispositioned
• URS requirements without corresponding tests in the traceability matrix
• System changes implemented in production without a change control evaluation
• Validation package not updated following a software upgrade
• Electronic signatures not configured to meet 21 CFR Part 11 requirements

Each of these represents a documentation gap, not necessarily a system malfunction. FDA inspectors are looking for evidence that your quality team maintains control over the software, understands what it does, and can demonstrate that through records.

What to ask a QMS vendor about their validation package

Before selecting a QMS platform, use these questions to evaluate the actual scope of any vendor’s validation claims:

• What does your validation package include per release — IQ only, or IQ/OQ with test results?
• Is the validation package provided at no additional cost, or is it a paid service?
• How is the validation package updated when you release a new platform version?
• What is the process for change control documentation when customers upgrade?
• Does your platform support separate dev, QA, and production environments?
• Do you provide 21 CFR Part 11 compliance documentation for electronic signatures?
• Is your infrastructure validated and documented (IQ for the hosting environment)?
• How do you document your own software development lifecycle (SDLC) process?

A vendor that struggles to answer these questions clearly has likely not invested in true pre-validation infrastructure.

Key takeaways

FDA requires QMS software to be validated because the records it generates are the foundation of your quality system. The 2022 CSA guidance reduced documentation burden by emphasizing risk-based testing and leveraging vendor documentation, but did not eliminate the validation obligation.

Pre-validated cloud QMS platforms reduce your validation cost and timeline by providing vendor-executed IQ/OQ documentation, tested update packages, and infrastructure qualification. Your URS and PQ remain your responsibility — they reflect your specific processes and environment, which no vendor can validate on your behalf.

The right platform makes validation a manageable, repeatable process. If your current approach looks more like a multi-year construction project than a quality process, it may be time to look at what a pre-validated platform actually delivers.
