What this episode covers

Nathan Roman, a validation and temperature mapping expert with over 23 years of experience, explains the evolution of environmental validation in the life sciences industry. He details the shift from bulky wired thermocouples to wireless data loggers and paperless systems like Neat, which streamline protocol execution and documentation. Roman distinguishes between temperature mapping as a standalone study versus its role within broader equipment qualification (IQ/OQ/PQ), noting that modern CQV practices combine commissioning and qualification to reduce redundant testing. He also covers specific challenges in maintaining cold chain integrity, including the use of liquid nitrogen vapor phase storage and real-time monitoring during shipping validation.

    Implementing an eQMS after Switching from Paper

    Kendyl Williams, a Medical Device Guru at Greenlight Guru, details her experience transitioning a medical device company from a paper-based Quality Management System (QMS) to the Greenlight Guru eQMS platform. She describes the logistical failures of the paper system, such as 'document signing parties' and lost binders, and explains how the team validated the new software by locking themselves in a coffee shop to test workflows. Williams highlights the importance of using the sandbox environment to learn the system without risking live data and emphasizes the need for intentional setup regarding document nomenclature and attributes to ensure traceability between risk and design controls.
