An interactive decision-support tool that maps a system’s characteristics to the appropriate validation approach based on principles, while flagging outdated GAMP 4 practices.
GAMP 5 changed the relationship between the regulated company and the software vendor.
| Category | GAMP 4 Definition | GAMP 5 Definition & Change | | :--- | :--- | :--- | | | Infrastructure Software (OS, Database). | Infrastructure Software. Unchanged in principle, but GAMP 5 places greater emphasis on verifying the infrastructure (e.g., network drawings, patch management) rather than validating the OS itself. | | Category 2 | Firmware/Instrument. | Removed. GAMP 5 dissolved this category. Simple instruments are now generally handled under Category 3 (standard components) or through a simplified hardware validation approach, acknowledging that modern instruments are rarely just "firmware." | | Category 3 | Standard Software Packages. | Non-Configured Products. Refined to emphasize that these systems are used "out of the box" with no custom configuration. Validation focuses on business process fit. | | Category 4 | Configured Software Packages. | Configured Products. This remains the most common category (e.g., LIMS, SCADA). GAMP 5 emphasizes risk-based testing here—testing configuration and custom code heavily, while testing standard functions based on risk. | | Category 5 | Custom Software. | Custom Applications. Still requires the full rigor of the V-Model (including code review) because the organization is building the software from scratch. |
flexible, risk-based lifecycle approach . While GAMP 4 focused on a rigid "one-size-fits-all" waterfall model, GAMP 5 allows organizations to scale validation efforts based on the risk to patient safety, product quality, and data integrity.
