In this episode, Chuck and Howie sit down with Stephen Doty to reflect on a career that spans Navy calibration work, pressure and vacuum metrology, accreditation program leadership, and quality management at NASA. Stephen shares what brought him out of retirement and into the metrology lab at Marshall Space Flight Center, and how that environment encourages collaboration, shared best practices, and true partnership with internal customers. The conversation explores the evolution from legacy standards to ISO/IEC 17025, why ongoing education (for both labs and customers) matters, and how contract review and process consistency help prevent “quality blind spots.” They also discuss how accreditation has changed over time, what labs should consider when choosing an accreditation body, and why proficiency testing and interlaboratory comparisons remain essential tools for validating competence and improving measurement performance. The episode wraps with Stephen’s personal path into metrology and practical advice for those entering the field: stay curious, ask questions, and be a sponge for learning.
