Subject matter experts (SMEs) are individuals who possess and demonstrate a high degree of specialized knowledge, skills, and experience in a particular technical domain, process, or technology. They are recognized as authoritative sources within their field, providing guidance, insights, and informed decision-making. Their expertise is characterized by a combination of up-to-date theoretical understanding and extensive practical experience, contributing significantly to the success of complex projects and initiatives. However, one critical facet distinguishes SMEs who make a significant impact: their willingness to challenge the status quo. This attribute is particularly important when developing codes and standards, as progress in this realm comes from pushing technological boundaries, documenting the basis for change, and shifting existing beliefs to drive industry advancements and effect meaningful change. Notable examples of such SMEs in the materials field include Dr. Martin Prager, Dr. Carl Lundin, and Dr. Howard Voorhees, whose work has significantly influenced the refining, petrochemical, chemical, fossil utility, and nuclear industries. This article explores the role of SMEs in shaping technological advancements and industry standards, focusing on their ability to challenge and evolve the status quo.
