Computer Software Assurance

Overview

Computer Software Assurance (CSA) is a risk-based approach to establishing confidence that software used in regulated operations performs as intended.

Mediature GxP Solutions Pvt. Ltd. (MGS) supports pharmaceutical, biopharmaceutical, API, medical-device, laboratory, and other regulated organizations with CSA strategy, risk assessment, assurance planning, testing, documentation, supplier evaluation, and lifecycle support.

Our approach focuses on critical thinking, intended use, software risk, patient safety, product quality, data integrity, and efficient verification, helping clients apply the appropriate level of assurance without unnecessary documentation or testing.

Our CSA Services

CSA Strategy Development

Development of risk-based assurance strategies defining system scope, intended use, critical functions, testing depth, responsibilities, and documentation requirements.

Intended Use Assessment

Evaluation of how the software is used, which business processes it supports, and whether failures could affect quality, safety, or regulated records.

Software Risk Assessment

Assessment of software functions and potential failure modes to determine the level of assurance required.

Critical Function Identification

Identification of functions that can directly or indirectly affect:

• Product quality
• Patient safety
• Data integrity
• Regulatory compliance
• GxP records

Assurance Testing

Development and execution support for testing focused on critical functionality and meaningful risk scenarios.

Unscripted & Exploratory Testing Support

Where appropriate, support for risk-based exploratory or unscripted testing to efficiently evaluate software behavior and critical workflows.

Scripted Testing

Development of formal test scripts for higher-risk functions where structured execution and predefined evidence are appropriate.

Supplier Assessment

Evaluation of software vendors, development practices, quality systems, documentation, support arrangements, and lifecycle responsibilities.

Configuration & Workflow Review

Assessment of configured workflows, roles, permissions, calculations, reports, controls, and other GxP-relevant functions.

CSA Documentation Review

Preparation or review of assurance records to ensure that risk decisions, testing, evidence, deviations, and conclusions are appropriately documented.

Key CSA Considerations

Depending on the system, MGS may evaluate:

• Intended use
• GxP impact
• Software risk
• Process criticality
• Patient-safety impact
• Product-quality impact
• Data-integrity impact
• System complexity
• Configuration
• User access
• Electronic records
• Audit trails
• Calculations
• Workflows
• Interfaces
• Data transfer
• Automation
• Supplier controls
• Cybersecurity considerations
• Change management
• Incident history
• Periodic review
• System retirement

CSA vs Traditional CSV

CSA does not eliminate validation or documented assurance. Instead, it emphasizes a more focused and efficient approach based on actual risk.

A CSA approach may place greater emphasis on:

• Critical thinking
• Intended use
• Risk-based assurance
• Higher focus on critical functions
• Flexible testing methods
• Leveraging supplier evidence
• Reduced low-value documentation
• Greater emphasis on actual system performance
• Appropriate use of exploratory testing
• Lifecycle assurance

For higher-risk or highly critical functions, more formal scripted testing and documentation may still be appropriate.

Our Approach

• Understand

Define the software, intended use, business process, users, data, and regulatory relevance.

• Assess Risk

Evaluate potential failure modes and determine impact on quality, safety, compliance, and data integrity.

• Define Assurance Level

Determine which functions require formal scripted testing, exploratory testing, supplier evidence, or other assurance activities.

•  Verify

Perform or support risk-appropriate testing of critical software functions and workflows.

•  Evaluate Evidence

Review testing, supplier documentation, deviations, configuration, and supporting evidence.

• Release & Maintain

Confirm suitability for use and support change control, periodic review, incident management, and continued assurance.

CSA Deliverables

Depending on scope, MGS can provide:

• CSA strategy
• Intended-use assessment
• GxP impact assessment
• Software risk assessment
• Critical-function matrix
• Assurance plan
• Supplier assessment
• Scripted test cases
• Exploratory testing records
• Configuration review
• Traceability documentation
• Deviation assessment
• Assurance summary report
• Change-impact assessment
• Periodic-review support
