Building a Risk-Based Validation Operating Model

This white paper outlines a practical playbook for Life Sciences organizations transitioning from traditional Computer System Validation (CSV) to a more modern Computer Software Assurance (CSA) operating model. It emphasizes the importance of risk-based validation without compromising patient safety, product quality, or data integrity. The document details how conventional CSV practices often lead to excessive documentation without enhancing confidence in software functionality. The CSA model shifts focus from exhaustive testing of low-risk features to a more critical assessment of intended use, risk, and controls. The paper describes the necessary changes in organizational decision-making regarding validation, advocating for standardized deliverables and clear approvals. It also presents a phased implementation roadmap, starting with an inventory assessment and progressing through standardization and optimization phases. The conclusion reinforces that CSA represents an evolution in validation practices, aiming for more effective and defensible processes aligned with actual patient and product impacts.
