Basic Steps for Formal System Validation

The FDA mandates that equipment used to monitor the temperature in blood bank refrigerators and freezers or cleanrooms in compounding pharmacies be formally validated. Validation is a process that begins with a user requirements specification (URS) system. From this, the monitoring system is designed and a System Design Specification (DSD) (sometimes called an SRS) is created. This is followed by tests to verify and document that 1) the system components were installed and configured correctly (IQ), 2) that they function properly (OQ), and 4) that they meet the applications specific needs (PQ). The available CIMScan validation template package contains a precise framework to allow each of these documents to be easily and accurately created.

The SDS (SRS) template is an all-encompassing generic requirements specification and is provided as a MS Word document that has been specifically structured to provide the foundation for the IQ, OQ, and PQ protocols. The prospective user simply fills in the blanks and makes various selections or additions to tables.

The Installation Qualification Protocol (IQ) is a template that is expanded based on the component tables contained in the SDS. Also included are sections where the user verifies the availability of pertinent Standard Operating Procedures. A major part of the IQ is devoted to verifying that the system is configured to match the requirements in the SDS. There is a 1:1 mapping of the requirements to the IQ which eliminates the need for a traceability matrix.

The Operational Qualification Protocol (OQ) is supplied as a completely executed and fully documented package that covers the entire CIMScan server software product. The tests exhaustively verify the functionality and workflow of the operation of the system. You can choose to use the OQ as is, or an unexecuted version can be supplied for you or a third party validation contractor. Again, the OQ protocol matches the requirements stated in the SDS.

The Performance Qualification Protocol (PQ) is used to verify the critical operations for your specific application. These include sensor accuracy, data recording, data display, alarm detection, and alert delivery.

It typically takes less than a week to prepare the validation documents for a medium sized lab or cleanroom monitoring application through a web based cleanroom monitoring system. Once the documents are available and have been approved, the installation can start. The IQ is normally executed during the installation process and should only take a half day to fill in. Once the system is operational, the PQ for a system with 30 points can be easily executed and documented in less than two days.
