• Examine the supplier’s Quality Management System (QMS) documentation relevant to software development and maintenance.
• Review validation documentation, including Software Requirement Specifications (SRS), risk assessments, testing protocols, and Change Control Process.
• Assess supplier’s compliance with standards such as ISO 9001 and ISO/IEC 27001, if applicable.

Interview Key Personnel

• Discuss with software developers about the SDLC adherence and incorporation of GAMP principles.
• Engage quality assurance representatives to understand audit trails and CAPA implementation.
• Assess support and maintenance teams on incident management and software updates procedures.

Evaluate Software Lifecycle and Controls

• Verify that the software development lifecycle includes risk management, validation, testing, documentation, and release controls consistent with GAMP categories.
• Confirm supplier maintains traceability from user requirements through to testing and deployment.
• Examine configuration management practices ensuring integrity and version control.

Assess Security and Data Integrity Measures

• Evaluate access control mechanisms, encryption practices, and audit trail capabilities.
• Confirm compliance with 21 CFR Part 11 requirements, particularly electronic records and electronic signatures.
• Review backup, disaster recovery plans, and incident response frameworks.

Observing tangible evidence during the audit mitigates risks associated with incorporating third-party software systems into GxP environments and supports ongoing compliance with regulatory bodies such as the EMA.

Step 3: Performing the Technical Assessment of Software

Parallel to the supplier audit, the technical assessment evaluates the software’s design and suitability to meet regulatory expectations and user requirements under GAMP software validation.

Analyze Software Architecture and Design

• Review software structural documentation to confirm modularity, maintainability, and scalability.
• Ensure software design addresses intended use, operational environment, and integration points with other systems.
• Evaluate compliance with industry standards – for example, IEC 62304 for medical device software when relevant.

Assess Software Functionality and Performance

• Compare delivered software functionality against User Requirement Specifications (URS).
• Utilize documented testing results including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).
• Verify defect tracking and resolution processes demonstrate continuous quality improvement.

Review Risk Management Records

• Confirm risk assessments conducted per ICH Q9 and integrated within the software development lifecycle.
• Evaluate mitigation measures for identified risks, and their validation within operational procedures.
• Analyze residual risk evaluations to ensure acceptability per company and regulatory standards.

Evaluate Documentation Completeness and Quality

• Check that all deliverables conform to documentation practices required by GMP and GAMP 5 guidelines.
• Ensure traceability matrices link requirements to testing effectively.
• Review Change Control documentation and version histories for transparency and governance.

Security, Data Integrity, and Compliance Verification

• Verify software supports regulatory controls to preserve data integrity in GxP computer systems.
• Review audit trail features enabling thorough investigation of data changes.
• Ensure mechanisms exist to prevent unauthorized access or data manipulation consistent with 21 CFR Part 11 and Annex 11.

This detailed technical assessment complements the supplier audit by providing a focused evaluation of the software itself, reinforcing the compliance posture of the overall system as recommended by PIC/S GAMP guidance.

Step 4: Reporting and Follow-Up Actions

After executing the audit and technical assessment, the next essential step is to document findings and define corrective measures to address any identified gaps or risks before proceeding further in the software validation process.

Prepare a Comprehensive Audit Report

• Detail the scope, objectives, approach, and limitations of the audit and assessment.
• Summarize observations, non-conformances, and areas of excellence.
• Include evidence-based findings with references to specific documents, interviews, and observations.

Risk Categorize Findings and Recommend Actions

• Classify findings by severity and potential impact on product quality and patient safety.
• Suggest corrective action plans (CAPA) with clear ownership and timelines for resolution.
• Highlight positive practices for recognizing supplier strengths and fostering continuous improvement.

Conduct Closing Meeting with Supplier

• Present preliminary findings and discuss potential corrective actions constructively.
• Allow supplier to provide additional information, clarifications, or commitments.
