QMS Software Validation: Definition, Process, and Requirements

QMS software validation is a documented, systematic process that ensures a Quality Management System (QMS) software consistently performs as intended and meets predefined user and compliance requirements. In highly regulated industries like life sciences, QMS software validation is important because it preserves data integrity, product quality, and patient safety.

The QMS software validation involves a lifecycle-based eleven-step process designed to confirm the reliability and compliance of the system.

1. Risk Assessment: Risk assessment identifies and evaluates software risks to determine validation scope and depth.
2. Validation Planning: Validation planning defines the validation strategy, objectives, scope, roles, deliverables, and acceptance criteria. A traceability matrix links each requirement to test cases to ensure complete coverage.
3. User Requirement Specifications (URS): URS establishes and documents the operational and compliance requirements that software must fulfill to support intended use.
4. Functional and Design Specifications Review: Functional and design specifications translate the URS into technical design and ensure alignment with user needs.
5. Installation Qualification (IQ): IQ verifies that software and infrastructure are installed correctly.
6. Operational Qualification (OQ): OQ confirms that all software functions work under controlled conditions.
7. Performance Qualification (PQ): PQ confirms that the software performs reliably in the actual working environment.
8. Validation Reporting and Release for Use: Validation reporting summarizes all validation activities, and release for use provides a documented approval that the system is fit for its intended use and authorized for operational use.
9. Change Management: Change management refers to all software changes or updates and their proper handling, assessment, testing, and documentation, to preserve the software’s validated state.
10. Periodic Review: During periodic review, the system is assessed to confirm it remains validated and compliant.
11. Software Retirement: Proper software retirement ensures data integrity and accessibility when decommissioning software.

The requirements for QMS software validation stem from various standards, guidelines, and regulations. Key requirements include FDA 21 CFR Part 11 for electronic records and signatures, EU GMP Annex 11 for computerized systems in Good Manufacturing Practice environments, ISO 13485:2016 for medical devices QMS, and GAMP 5, which provides a risk-based framework for validation.

To ensure ongoing compliance for a validated eQMS, organizations must establish robust change control processes, perform scheduled periodic reviews, revalidate the software after significant changes, maintain secure system administration, and follow SOPs for operation, security, and data management. 

The main benefits of QMS software validation include enhanced regulatory compliance and audit readiness, reliable system performance, and improved data integrity and operational efficiency.

What Is QMS Software Validation?

QMS software validation is a documented, systematic process that demonstrates that Quality Management System (QMS) software consistently performs as intended and meets predefined requirements.

The key objective of QMS software validation is to confirm that the system is suitable, consistent, and reliable. In highly regulated industries, such as life sciences, validation supports compliance with applicable regulatory requirements and industry standards.

Software validation differs from verification. According to the FDA’s general principles of software validation, software verification provides objective evidence that specific design outputs of a particular phase meet the defined requirements for that phase. Software verification supports the conclusion that the software is validated. Validation confirms that software specifications align with user needs and intended uses, and that requirements are met consistently.

The key components typically validated in a QMS software system are the following.

• Access Management: Access management validation focuses on role-based permissions, user authentication, and user privilege assignments. The QMS software is tested to confirm that users can only access the functions and data appropriate to their job role, preventing unauthorized access or changes.
• Electronic Signatures. Electronic signatures are validated to confirm that each electronic signature is uniquely attributable to a single user and is securely linked to the corresponding record. The system must require user authentication before signature and capture the user’s name, date, and time of signature.
• Audit Trail: Audit trail functionality is validated to confirm that the system automatically generates secure, computer-based logs capturing user actions. Audit trails must include user ID, time, date, and details of record creation, modification, or deletion, including the reason for change where required.
• Data Management (entry, storage, migration): Data management processes are validated to ensure accurate data entry, secure storage, and long-term data preservation. Validation of the data migration process confirms that data are not altered in value and/or meaning during the migration process.
• Built-in Workflows: Workflows embedded in the QMS are validated to enforce Standard Operating Procedure (SOP) adherence through automated routing, approvals, and task management. Validation of built-in workflows confirms that each process step aligns with the defined SOP steps.

Why Is QMS Software Validation Important?

QMS software validation is important because it confirms that the software can be relied upon to control and document critical quality processes in a compliant and consistent manner.

The main benefits of validating QMS software are listed below.

• Improved Compliance: QMS software validation is mandated by different regulatory requirements, such as FDA 21 CFR Part 11 and EU Annex 11, and international standards such as ISO 13485:2016.
• Assured Product Quality: Validation ensures that the QMS software consistently supports quality-related processes, helping organizations safeguard the quality of their products.
• Proactive Risk Management: Validation identifies and mitigates potential software risks before system deployment, reducing the likelihood of process failures or compliance gaps that could impact data integrity, product quality, or safety.
• Assured Data Integrity: Validation confirms that the system accurately records, stores, and protects data, ensuring traceability of actions and accountability.
• Enhanced Operational Efficiency: Validation ensures that automated workflows and software integrations function correctly, enabling faster, error-free processes that save time and reduce manual effort in daily quality management operations.

What is the QMS Software Validation Process?

The QMS software validation process ensures that the software consistently performs as intended and meets all regulatory, technical, and operational requirements. According to Good Automated Manufacturing Practice (GAMP) 5 guidelines, the extent of validation must be determined on a case-by-case basis using critical thinking and risk assessment. The validation process must cover the entire software lifecycle.

The eleven stages of the QMS software validation process are listed below.

1. Risk Assessment: Risk assessment is the fundamental step that determines the potential risks the QMS software may pose to product quality, patient safety, data integrity, and compliance. The results of the risk assessment define the validation scope and depth.
2. Validation Planning: A validation plan is developed, defining the validation strategy, scope, objectives, resources, responsibilities, deliverables, including a traceability matrix, and acceptance criteria, aligned with the system’s risk level and intended use.
3. User Requirement Specifications Definition: The regulated company defines clear and verifiable user requirements that the QMS software must meet to support operational and compliance needs. The requirements are linked to test cases through the traceability matrix.
4. Functional and Design Specifications Review: Functional specifications derive from user requirements, while design specifications describe the technical and system components required to meet them. Input from the software supplier is critical at this stage, as these specifications reflect the software’s technical design and configuration.
5. Installation Qualification (IQ): IQ verifies that the software, including associated hardware and network components, is correctly installed and configured in the intended environment.
6. Operation Qualification (OQ): OQ confirms that the QMS software functions as intended under predefined and controlled conditions, in accordance with the functional and design specifications.
7. Performance Qualification (PQ): PQ verifies that the QMS software performs as expected in its actual operational environment using real business data or realistic test scenarios.
8. Validation Reporting and Release for Use: Validation reporting summarizes all validation activities, including test results, deviations, and conclusions, and provides documented approval that the system is fit for its intended use and authorized for operational use.
9. Change Management: During the software operational phase, all system changes or updates must be properly documented and assessed, following the formal change management procedure.
10. Periodic Review: The regulated user must perform regular reviews to ensure the QMS software remains validated throughout its lifecycle, particularly after software updates or configuration changes.
11. Software Retirement: When the validated system is replaced or decommissioned, data retention, migration, or archival procedures shall be in place to maintain regulatory compliance and ensure data integrity and accessibility.

Documents typically generated during the validation process include a validation plan or protocol and report, user requirement specifications, and IQ/OQ/PQ protocols and reports.

1. Risk Assessment

Risk assessment is the systematic process of identifying and evaluating potential risks associated with the use of QMS software.

Risk assessment is critical in QMS software validation because it determines the extent of validation and focuses resources on the most critical areas. Risk assessment ensures that validation efforts are proportionate to the potential impact on product quality, patient safety, and data integrity, thereby optimizing effort and minimizing compliance risks.

The three main steps in QMS software validation risk assessment are the following.

1. Risk Identification: The risk identification step defines the potential risks related to software use. In QMS software, risk identification focuses on threats to data integrity, security, and regulatory compliance.
2. Risk Analysis: The risk analysis step includes the assessment of the severity, likelihood, and detectability of each identified risk to understand the potential impact on product quality, compliance, or data integrity.
3. Risk Evaluation: At the risk evaluation step, risks are ranked and prioritized based on their overall significance to determine which areas require the most rigorous validation and control measures.

The primary documentation generated from risk assessment is the risk assessment report, which records identified risks, their analysis and evaluation, and frames the validation plan.

The risk level of QMS software is linked to GAMP 5 system categorization. QMS software is generally classified as Category 4 (configured software) or Category 5 (customized software) depending on the level of configuration or customization required. Less configurable, off-the-shelf systems may fall under Category 3, requiring less extensive validation effort.

Several standards and regulatory requirements mandate a risk-based approach to computer system validation, including EU GMP Annex 11, GAMP 5, FDA Computer Software Assurance (CSA) guidance, ISO 13485, and ISO/TR 80002-2:2017. For risk management principles, organizations should follow ICH Q9, which outlines a systematic framework for identifying and controlling risks.

Risk assessment supports risk mitigation by linking identified risks to software requirements, test cases, and validation activities. The alignment between risk assessment and validation planning guarantees that all significant risks are addressed through appropriate controls and verification steps.

2. Validation Planning

Validation planning is the structured and comprehensive process of defining the scope, approach, resources, responsibilities, deliverables, schedule, and acceptance criteria for the QMS software validation. The validation plan must cover the entire QMS software lifecycle.

Validation planning is important in QMS software validation because it provides a clear roadmap for execution, defines the scope and boundaries of validation, and establishes a documented basis for audits. The validation plan ensures that all validation activities are consistent, traceable, and aligned with regulatory expectations.

The six main elements of the validation plan are listed below.

1. Scope and Objectives: Scope and objectives define which software, modules, or functionalities will be validated and specify the overall goals of validation.
2. Roles and Responsibilities: Roles and responsibilities identify the validation team, including QA, IT, the system owner, and end users, and clarify who is responsible for specific validation tasks and oversight. The responsibility for reviewing and approving this work should be clearly assigned when the software vendor performs part of the validation.
3. Validation Strategy: The validation strategy establishes the validation approach based on risk assessment outcomes and GAMP 5 categorization, including the validation methodology to be followed, such as the V-model or agile methodologies.
4. Validation Deliverables: Validation deliverables specify the required documentation, including User Requirements Specifications, risk assessments, validation traceability matrix, test protocols, test reports, and related evidence, along with timelines and required resources for each deliverable.
5. Acceptance Criteria: Acceptance criteria define the objective, measurable criteria that determine whether validation outcomes are acceptable and demonstrate that the system performs as intended.
6. Deviation and Change Management: The deviation and change management section defines the processes for handling deviations and changes that occur during validation, including documentation requirements, impact assessment, and resolution procedures.

The key documentation concluding validation planning is the validation plan, or validation protocol, which serves as the primary reference for all subsequent validation activities.

Validation planning is a fundamental regulatory expectation referenced by EU GMP Annex 11, GAMP 5, FDA computer software assurance guidance, and ISO/TR 80002-2:2017.

3. User Requirement Specifications (URS)

The User Requirement Specifications (URS) define in clear and measurable terms what end-users need the software to do, including both operational and compliance requirements.

URS are essential in QMS software validation because they provide a clear description of the regulated user’s expectations and ensure that the system meets all compliance obligations. For example, if an FDA-regulated company implements a QMS software with electronic signature capabilities, the URS should specify that electronic signatures applied through the software must comply with FDA 21 CFR Part 11, such as requiring at least two distinct identification components for non-biometric signatures. The URS provides the foundation for test case development.

The five main elements of the URS definition in the context of QMS software validation are given below.

1. Gathering of Requirements: Requirements should be collected based on the input from multiple sources, including end-users, IT, and the quality team, to define what the system must achieve.
2. Categorization of Requirements: URS are grouped by module or function, such as document management, equipment management, or audit management, to maintain clarity and focus. Non-functional requirements, such as those supporting usability, compliance, and integration, should also be listed.
3. Establishment of URS: The URS established must be clear, testable, and traceable to facilitate verification and traceability during validation.
4. Prioritization of URS: The URS may be ranked according to their criticality and impact.
5. Review and Approval of URS: URS shall be reviewed and approved by key stakeholders, including QA, system owners, IT, and end users.

The primary output generated during URS definition is the documented URS, which may be included in the validation plan or maintained as a separate controlled record.

The establishment of URS is mandated by EU GMP Annex 11 and referenced in the FDA general principles of software validation and GAMP 5.

The URS ensures traceability and risk mitigation by serving as the starting point for the traceability matrix. Each test case executed during performance qualification must link directly to one or more URS requirements, ensuring that all user and compliance needs are fully covered.

4. Functional and Design Specifications Review

The Functional Specifications (FS) define what the system must do to meet user requirements, while the Design Specifications (DS) define how the system will be built or configured to achieve those functions.

Functional and design specifications review is crucial in QMS software validation because it bridges the gap between user expectations and technical realization.

Both functional and design specifications are typically defined during the software development phase by the QMS software vendor and reviewed and approved by the regulated user to confirm that they meet intended use and compliance needs.

Functional and design specifications review contributes to risk mitigation by clarifying system boundaries and verifying that identified risks are addressed through appropriate design controls.

5. Installation Qualification (IQ)

Installation Qualification (IQ) is the process of verifying and documenting that a computerized system has been delivered, installed, and configured correctly according to its design specifications and the manufacturer’s recommendations within the intended operating environment.

IQ is critical in QMS software validation because it establishes a proper foundation for the system. A system that is not installed correctly cannot be expected to function reliably.

The five main steps in the IQ of a QMS software are the following.

1. IQ Protocol Preparation: IQ protocol preparation is the development of a protocol outlining objectives, acceptance criteria, and responsibilities for verifying system installation.
2. IQ Protocol Review and Approval: IQ protocols are reviewed and approved before execution, usually by QA, IT, process, and system owners.
3. IQ Protocol Execution: During the IQ protocol execution, the installation verification activities, including hardware and software setup, network configuration, user account creation, and verification of software version and components, are performed.
4. IQ Report Compilation: Upon completion, IQ activities are summarized in the IQ report, noting any deviations and confirming that all installation requirements have been met.
5. IQ Report Review and Approval: The IQ report is reviewed, along with the supporting evidence, and approved, usually by QA, IT, process, and system owners.

The documentation generated during IQ includes the IQ protocol, IQ report, and supporting evidence such as logs or screenshots, and any deviation records if applicable.

IQ ensures system reliability by confirming that the QMS software is correctly installed and configured, providing a stable and compliant base for subsequent operational and performance qualification.

6. Operation Qualification (OQ)

Operational Qualification (OQ) is the process of verifying and documenting that a computerized system operates as intended across all specified functions, in accordance with the functional and design specifications, under controlled test conditions.

OQ is essential in QMS software validation because it confirms that the system performs reliably within defined operational limits before it is used in the production environment. OQ ensures that each function works correctly, all workflows execute as designed, and required controls, such as security, audit trails, and electronic signatures, are functioning in compliance with URS.

The six main stages of OQ during the validation of a QMS software include the following.

1. OQ Protocol Preparation: During OQ protocol preparation, a detailed plan, defining objectives, scope, test cases, acceptance criteria, and responsibilities, is developed.
2. OQ Protocol Review and Approval: The OQ protocol is reviewed for completeness, accuracy, and traceability, and approved by relevant stakeholders before testing begins.
3. OQ Test Execution: During OQ test execution, functional and operational tests are performed under simulated or controlled conditions.
4. Deviation Management: Any deviation that occurred during OQ shall be recorded and assessed, and corrective actions shall be implemented where necessary.
5. OQ Report Compilation: In the OQ report, the executed test cases and their results are documented, confirming if the acceptance criteria have been met.
6. OQ Report Review and Approval: The OQ report shall be reviewed and approved by relevant stakeholders, such as QA, IT, system or process owners, to confirm successful completion.

The documentation generated from OQ includes the OQ protocol, OQ report, executed test scripts, test evidence (such as logs and screenshots), and, if applicable, deviation records.

OQ supports system reliability by verifying that all functional and design requirements are tested and documented.

7. Performance Qualification (PQ)

Performance Qualification (PQ) is the documented process of confirming that a computerized system consistently performs as intended when operated in its actual user environment.

PQ is critical in QMS software validation because it verifies that the system supports day-to-day quality operations under normal operating conditions.

The six main steps in the performance qualification of a QMS software are given below.

1. PQ Protocol Preparation. A PQ protocol is prepared to define objectives, scope, test cases, acceptance criteria, and responsibilities for verifying system performance in the production environment.
2. PQ Protocol Review and Approval: The PQ protocol is reviewed and approved by responsible personnel before test execution.
3. PQ Test Execution: During the PQ test execution, end-to-end process testing is performed using real or representative data and actual workflows to confirm that the system functions correctly during routine operations. PQ tests include confirming that access rights, permissions, audit trail, and electronic signature functionalities align with operational and compliance requirements.
4. Deviation Management. Any deviations found during PQ testing are reviewed and evaluated, and corrective actions are taken if needed.
5. PQ Report Compilation: PQ executed tests, results, deviations, and conclusions are documented in the PQ report, confirming if all acceptance criteria were met.
6. PQ Report Review and Approval: The PQ report obtains formal approval usually from IT, QA, system, and process owners.

The typical PQ documentation includes the PQ protocol, PQ report including executed test cases, test evidence (e.g., screenshots, logs), and deviation records.

PQ ensures system reliability and fitness for use by confirming that each URS is fulfilled. Through direct linkage of test cases to requirements in the traceability matrix, PQ provides documented assurance that the system consistently delivers accurate, reliable, and compliant performance during actual operations.

8. Validation Reporting and Release for Use

Validation reporting and certificate issuance are the final phases of QMS software validation, where all validation activities are summarized to confirm that the system meets its intended use and regulatory requirements. The validation reporting stage provides the official validation conclusion, confirming that the software is validated and fit for operational use.

This step is crucial in QMS software validation because it consolidates evidence from the entire validation process and serves as the definitive record demonstrating compliance.

The four main elements of the validation reporting stage are the following.

1. Validation Summary Report Preparation: Compilation of a validation summary report, including risk assessment, traceability matrix, IQ, OQ, and PQ outcomes, along with any deviations and their resolutions.
2. Review of Supporting Documentation: The responsible personnel, including quality assurance, system owner, and other key stakeholders, review the validation report and all supporting documentation to verify completeness, accuracy, and consistency.
3. Validation Conclusion and Approval: The company formally concludes that the QMS software meets defined acceptance criteria and complies with applicable requirements.
4. System Release for Production Use: Following approval of the validation summary report, the system is formally released for routine production use. Some organizations issue a supplementary validation certificate, usually signed by QA and the system owner.

The validation summary report and the validation certificate are generated and serve as official evidence of validation completion.

The validation report is the primary document proving that a computerized system has been properly validated and authorized for use. Thus, the validation report acts as primary evidence of compliance with several regulatory requirements and industry standards, including EU GMP Annex 11, FDA 21 CFR Part 11, GAMP 5, and ISO 13485.

9. Change Management

Change Management is the process of evaluating, approving, implementing, and documenting any modification to a validated QMS software. Change management applies to software updates, configuration changes, patches, workflow adjustments, integrations, and infrastructure modifications.

Change management is important because it protects the validated state of the system and ensures ongoing compliance with regulatory requirements. Without a structured change control process, system updates could introduce unintended risks to product quality, patient safety, or data integrity.

The five steps involved in change management include the following.

1. Change Request Initiation: Formal documentation of the proposed change, including description, rationale, scope, and timelines.
2. Impact Assessment: Evaluation of the change’s impact on product quality, patient safety, data integrity, system compliance, and validation status.
3. Change Review and Approval: Review by Quality Assurance, IT, system owners, and process owners, to approve, reject, or request modification of the proposed change.
4. Testing and Implementation: Execution of defined testing activities, or revalidation activities, before deployment into the production environment.
5. Documentation: Recording all decisions, test results, approvals, and implementation evidence to maintain traceability and compliance.

Documentation generated from change management includes change control records and, where required, revalidation documentation.

Change management is referenced by EU GMP Annex 11, GAMP 5, and ISO/TR 80002-2:2017, all of which require lifecycle control and evaluation of system changes. ISO 13485:2016 requires that software be validated after changes when appropriate, reinforcing the need for structured change management.

Change management ensures risk mitigation and system reliability by systematically evaluating every modification before implementation. By assessing the impact of a proposed change, organizations prevent unmanaged risks that may compromise the software’s validated state or regulatory compliance.

10. Periodic Review

Periodic review is the process of regularly evaluating a computerized system during its operational phase to ensure that it remains validated and continues to meet its intended use.

Periodic review is important in QMS software validation because it addresses the operational phase of the system lifecycle, while earlier validation steps apply to the pre-release project phase. Periodic review provides continued assurance that the system remains fit for purpose despite any changes in use, environment, personnel or regulatory requirements over time.

The four main steps in the periodic review process are listed below.

1. Schedule Periodic Review: Companies shall establish specific periodic review intervals based on system risk, ensuring consistent oversight of QMS software validation status.
2. Perform Periodic Review: During the periodic review performance, the current system functionality, performance, reliability, and security are assessed by reviewing relevant records such as deviations, incidents, audit trails, and previous validation status reports.
3. Evaluate Changes and Configuration: At periodic review, the company must review all software updates or configuration changes to determine whether revalidation is required.
4. Conclude the Review: The periodic review concludes whether the QMS software remains validated or if revalidation is necessary.

The documentation generated from this step includes the periodic review report, which summarizes the assessment findings, and revalidation documentation, if revalidation activities are performed.

EU GMP Annex 11 and GAMP 5 both require periodic review as an ongoing lifecycle activity for maintaining validated systems. FDA guidance on software validation emphasizes evaluation of system changes and configurations, while ISO/TR 80002-2:2017 and ISO 13485 require that computerized systems be maintained and revalidated as necessary to ensure continued proper use.

Periodic review confirms if the QMS software remains validated throughout its operational lifecycle, maintaining compliance, data integrity, and system reliability over time.

11. Software Retirement

Software retirement is the controlled process of decommissioning a QMS software system that is no longer in active use while ensuring that all regulated data, records, and metadata remain accessible, accurate, and intact.

Software retirement is important in QMS software validation because it safeguards data integrity during and after system decommissioning.

The five key steps in software retirement are the following.

1. Planning the Retirement: Companies shall define a QMS software retirement plan outlining responsibilities, timeline, and required data retention measures.
2. Data Archival: Companies shall archive all regulated data, ensuring it remains complete, accurate, legible, and retrievable in compliance with record retention requirements.
3. Verification of Archived Data: Companies must confirm that archived data can be accessed and read, maintaining its integrity and authenticity. Data accessibility and retrievability during archive or migration shall be tested.
4. System Deactivation. Access to the retired software shall be disabled once data has been safely archived and verified, preventing unauthorized use or modification.
5. Documentation and Approval: All retirement activities shall be documented and approved by quality assurance, confirming that data integrity has been preserved.

Proper software retirement is required by EU GMP Annex 11 and GAMP 5, both of which require procedures to ensure data integrity when computerized systems are replaced or decommissioned.

Controlled software retirement ensures that critical quality and compliance information managed by the QMS software is preserved, traceable, and retrievable for audits or historical reference.

What Is the Relation Between IQ, OQ, and PQ?

IQ, OQ, and PQ are sequential stages in the QMS software validation process that collectively demonstrate the system’s reliability and suitability for its intended use.

IQ confirms that the QMS software and its supporting infrastructure are correctly installed and configured. OQ verifies that the system operates as intended under controlled conditions, ensuring that all functions perform correctly in accordance with the design and functional requirements. PQ confirms that the software performs reliably in the actual user environment, supporting real operational processes with consistent results.

During IQ, OQ, and PQ, each qualification phase builds upon the previous one. IQ establishes the foundation, OQ verifies functionality, and PQ confirms performance under real-world conditions.

Which Software Requires Validation?

Software requires validation when its use can directly or indirectly impact product quality, patient safety, or data integrity. Any software used in a regulated process must be validated to confirm it functions as intended and supports compliance. The extent and rigor of validation should follow a risk-based approach. The greater the software’s potential impact on product quality, patient safety, or data integrity, the more comprehensive and well-documented the validation effort should be.

The six factors that organizations must take into consideration to assess if validation is required are given below.

1. Regulatory or Industry Requirements: Organizations must check if applicable regulatory or standard requirements mandate computer system validation.
2. Intended Use: Organizations should define the purpose of the software and identify the specific quality or operational process it supports.
3. Impact on Product Quality and Patient Safety: Companies must evaluate whether a system failure or malfunction could affect product quality, safety, or process consistency, applying a risk-based approach.
4. Impact on Data Integrity: Life science companies should assess whether the software creates, modifies, processes, or stores data that is required by regulatory authorities or industry standards.
5. Use of Electronic Signatures or Electronic Records: Companies must identify if the system is used to manage official records or apply electronic signatures, replacing handwritten approvals, on regulated documents.
6. Integration with Other Validated Systems: Life science organizations must review whether the software interfaces with or transfers data to other validated systems, as any errors in the system under assessment may be transferred to the validated system.

The types of software that require validation are the following.

• Electronic Quality Management System (eQMS): An eQMS centralizes and digitalizes quality processes to enhance compliance, efficiency, and decision-making.
