Smarter GxP Audits via Computer Software Assurance

GxP Assessments and Audit Support under a Computer Software Assurance (CSA) framework shift the focus from checking boxes to evaluating critical thinking and risk management. Regulators (like the FDA or EMA) now evaluate how you determined risk, rather than how much paperwork you generated.

GxP System Assessment Framework

Before applying CSA, you must determine if a system falls under GxP regulations (GMP, GLP, GCP, GDP) and assess its risk impact:

1. Identification

System identification

2. GxP Impact

Impact assessment

3. Risk Category

Risk categorization

4. Assurance Level

Level selection

1. GxP Applicability Screening

Ask these filtering questions to identify GxP impact:

Does the software automate a regulated business process?
Does it generate, edit, or store data used for regulatory submissions?
Does a system failure directly affect patient safety or product quality?

2. Risk Categorization (High vs. Low)

High Risk (Direct Impact):
Software controlling a blood analyzer, managing batch release records, or executing sterile manufacturing processes.
Low Risk (Indirect Impact):
Employee training tracking tools, asset management software, or document workflow routing systems.

Conducting a CSA-Aligned Audit

When auditing internal systems or external software vendors, use the Critical Thinking approach over rigid compliance checklists:

Vendor Audits (SaaS & Commercial Providers)

Leverage Provider Data: Do not re-verify what the vendor has already thoroughly tested. Review their ISO certifications (e.g., ISO 27001, ISO 9001) and software development life cycle (SDLC) logs.
Audit the Automated Testing: Evaluate the vendor's internal automated testing maturity. High vendor maturity allows you to drastically reduce your own implementation testing.

Internal System Audits

Evaluate the Rationale: Ensure your team documented why certain features were classified as low risk. Regulators look for the scientific and data-driven justification behind your risk ratings.
Review Testing Mix: Check that the testing strategy matches the risk profile. High-risk features must have robust verification, while low-risk features can rely on unscripted or ad-hoc testing records.

Audit Readiness Checklist

Prepare your team to defend a CSA validation strategy during regulatory inspections with these items:

Approved CSA SOP

A standard operating procedure defining your risk-scoring criteria and unscripted testing rules.

The "Why" Matrix

A documented risk assessment showing clear rationales for feature categorization.

Vendor Assessment Reports

Proof that you verified the vendor's QA capabilities and are safely relying on their core testing.

Smarter Testing Records

Unscripted test logs capturing execution date, tester identity, system version, and clear pass/fail status without redundant screenshots.
